Two centenarian women, young again due to an anti-aging experiment, must escape a shadowy organization and face the terrifying prospect of becoming infants before they vanish.
In 2085, Melanie "Melly" and Annelise "Anny Beth" are physically fifteen and sixteen, but were born in 1900. They were part of Project Turnabout in 2000, which reversed their aging. Now, they grow younger each year, trying to blend in while keeping their secret. They live in a secluded house, staying hidden, and know they are nearing the age where they will be too young to care for themselves. They fear reaching 'age zero' and the unknown, as they were told the final treatment would be deadly. Their dwindling money and the difficulty of keeping up their youthful disguises add to their worry, making them consider drastic steps for their future.
Melly and Anny Beth realize they will soon be too young to live independently. They need a guardian, someone who won't exploit their condition or reveal their secret. Their current caretaker, a distant relative named Mrs. Smith, is old and forgetful, making her unsuitable for their long-term needs. They discuss options, including finding descendants of other Turnabout participants or sympathetic scientists. The challenge is finding someone they can trust with their secret, knowing their existence could lead to exploitation or public panic. They begin researching candidates, a task made hard by limited resources and the need for extreme care.
While searching for a solution, Melly and Anny Beth find evidence they are not alone. They discover a hidden community of others who also underwent Project Turnabout, living in a secluded, self-sufficient compound. These people, from young adults to children, are all aging backward, like them. The discovery is both a relief and a shock, as they thought they were the only survivors. They cautiously approach the community, observing their routines to understand how they live. This encounter gives them the first real hope that there might be a collective solution, not just an individual struggle.
Melly and Anny Beth join the new community, led by Sarah. Sarah, also a 'reverse,' acts as a mother figure, guiding younger members and keeping their secret. The community is set up to support individuals at different stages of reverse-aging, with older members caring for those who have become physically younger. Melly and Anny Beth learn the rules of this society, adapting to a life where their physical age changes constantly. They are relieved to be among others who understand, but also cautious of the community's strict rules and possible conflicts as they navigate new social dynamics.
The hidden community lives under constant threat of discovery by the outside world, especially the scientists who started Project Turnabout. They believe the original scientists see them as experiments to be recaptured or studied, not as people. Security is strict, and new members like Melly and Anny Beth are carefully checked. There are whispers of past close calls and the need for watchfulness. The tension of their unstable existence is clear, as any mistake could expose them and lead to everyone's capture. This shared danger creates solidarity but also deepens the fear of the unknown.
A central mystery in the community is what happens when a 'reverse' reaches 'age zero' — the point of conception. The original Project Turnabout scientists had warned of a 'deadly' final treatment, and the community has no clear answers, only theories and fears. Some believe it leads to death, while others hope for a complete reset or a return to normal aging. This uncertainty casts a shadow over their lives, especially for those like Melly and Anny Beth who are quickly nearing infancy. The older 'reverses' share their worries and guess about their ultimate fate, preparing for whatever comes. The fear of the unknown drives much of their decisions and desire for security.
As Melly and Anny Beth continue to age backward, they experience the community's cyclical nature. They watch older 'reverses' become younger, eventually needing care from those who are currently older. They themselves begin to take on responsibilities for younger 'reverses,' acting as caregivers. This role reversal constantly reminds them of their own fate. They learn to adapt to changing physical abilities and the emotional challenges of seeing peers revert to childhood. The experience deepens their understanding of the community's structure and their condition, preparing them for their own journey back through infancy.
As Melly and Anny Beth physically become younger children, their memories of their original adult lives begin to fade, a terrifying side effect. This creates new urgency to find answers about Project Turnabout and the true nature of 'age zero.' Despite their diminished physical abilities, their mental drive remains strong. They rely on the remaining older members, especially Sarah, to help them gather information and search for clues. They realize that understanding their past is key to securing their future, before their minds regress completely and they lose all sense of who they were. This quest for knowledge becomes a race against time and their own biological clock.
Through diligent searching and luck, Melly and Anny Beth, with Sarah's help, find hidden logs and data from Project Turnabout. These documents reveal the truth: the scientists never intended for participants to die at age zero. Instead, they believed reaching age zero would result in a 'reset' — a return to normal aging, but starting from conception. The 'deadly' warning was a scare tactic to keep participants from leaving early, ensuring they could be studied through the entire cycle. This discovery is a great relief, replacing fear with cautious hope, but also a betrayal, as the scientists deliberately misled them for decades.
With the truth about age zero revealed, the community holds a meeting. The fear of death is replaced by the understanding of a possible 'rebirth.' The question now is whether to accept this cycle or try to stop it. After much discussion, the community decides to let the process continue, accepting the possibility of a full 'turnabout.' This means that as individuals reach age zero, they will be cared for as infants, hoping they will then begin to age forward normally, effectively being reborn. Melly and Anny Beth, now very young, are among those who will soon go through this change, facing their future with both apprehension and hope.
Melly, having physically regressed to infancy, is one of the first in the community to reach 'age zero.' The community gathers, anxious but hopeful, to witness this event. She is carefully monitored by Anny Beth and other caregivers. The transition is not dramatic or 'deadly' as feared. Instead, she enters a state like a newborn, completely dependent, and seemingly without memory of her past lives. This observation gives the community valuable data and supports their belief in the 'reset' theory. Her journey through infancy becomes a beacon of hope and a practical test of their new understanding, solidifying their commitment to the cycle.
After Melly's successful transition through 'age zero,' Anny Beth, though still physically very young, takes on the main role of caring for the 'reborn' Melly. She dedicates herself to nurturing Melly, treating her as a new child, while hoping Melly's original personality and memories might resurface as she ages forward. This experience changes Anny Beth, giving her a deep sense of purpose and a greater understanding of the cycle of life. She and the other older members now focus on creating a stable, loving environment for those who are 'reborn,' preparing them for a second chance at a normal life, free from past fear.
The community, now confident in the 'reset' theory, begins to change its structure and focus. Their main goal shifts from survival and secrecy to creating a nurturing environment for those who have gone through 'turnabout' and are now aging forward normally. They set up systems for education, care, and integration into the wider world once they are old enough. The threat of the original scientists still exists, but the community is more united and strong. They are building a future where their condition is understood and managed, offering a second chance at life for many, including Melly, and eventually Anny Beth. The cycle of life, in its most extraordinary form, continues.
The story ends with the community thriving, a testament to their strength and adaptation. Melly, now a young child, grows up normally, unaware of her past. Anny Beth, still aging backward but nearing her own 'turnabout,' finds peace knowing there is a future beyond fear. The community's existence challenges ideas of time, identity, and mortality, becoming a quiet revolution against the forces that created them. They have not only survived but have made a new way of life, showing that even extreme circumstances can lead to unexpected hope and renewal. Their legacy is one of courage, community, and the human spirit.

This theme explores how reversed time shapes identity, memory, and human experience. Melly and Anny Beth, chronologically over 100 but physically teenagers, constantly struggle with their past selves and fading memories. The novel looks at the psychological impact of aging backward, where one's physical self conflicts with one's lived experience. Scenes where they struggle to recall details of their original adult lives, or when they watch others revert to infancy, show how fluid identity is when disconnected from linear time. The community's efforts to record their histories show a desperate attempt to ground their identities against the relentless flow of reverse aging.
“How could you be a teenager and a great-great-grandmother all at once? It was impossible. It was also their life.”
This theme explores the fear of 'age zero' and its shift into cautious hope. Initially, Melly, Anny Beth, and the community are paralyzed by the scientists' warning of a 'deadly' final treatment. This fear drives their secrecy and their desperate search for a solution. However, discovering the Project Turnabout logs changes this view, revealing the possibility of a 'reset' and a normal life. This shift from dread to tentative optimism, especially as Melly successfully navigates 'age zero,' highlights humanity's ability to find hope even in extraordinary and terrifying circumstances. The decision to embrace the cycle marks a major shift from survival to potential rebirth.
“For so long, 'age zero' had been a death sentence. Now, it was… a beginning.”
The novel emphasizes how important community and human connection are for overcoming extreme isolation and fear. Melly and Anny Beth initially live a solitary, paranoid life, showing the burden of their secret. Their discovery of the hidden community of 'reverses' is a turning point, offering not just physical safety but also emotional and psychological support. The community, led by Sarah, creates a system of mutual care, where older members protect and nurture younger ones. This collective effort, from sharing resources to collaboratively seeking answers, shows how shared experiences and belonging can empower individuals to face seemingly impossible challenges. Their bond is essential for survival and emotional well-being.
“Alone, they were just two old women trapped in young bodies. Together, they were a future.”
The story examines the ethical limits of scientific experimentation and the responsibility of creators towards their subjects. Project Turnabout, while achieving an incredible feat of reversing aging, is built on deception and disregard for human welfare. The scientists' decision to mislead participants about 'age zero' and their desire to study them as subjects highlights the dangers of science without ethics. The community's constant fear of recapture underscores the lasting impact of this scientific arrogance. The narrative implicitly asks whether pursuing knowledge justifies manipulating and causing suffering to individuals, ultimately favoring human dignity and autonomy over unchecked scientific ambition.
“They weren't just test subjects. They were people. And the scientists had forgotten that.”
The central scientific phenomenon where individuals physically grow younger over time.
Reverse aging is the core plot device that drives the entire narrative. It creates the unique challenges faced by Melly and Anny Beth, from maintaining their physical disguises to the existential crisis of losing their memories and identity. This device generates constant suspense as the protagonists race against their own biological clock. It also allows for intriguing social dynamics within the 'reverse' community, where caregiving roles are constantly shifting based on physical age. The mystery of 'age zero' is intrinsically linked to this device, making it the ultimate source of both fear and, ultimately, hope.
A secret society of other 'reverses' living in isolation from the wider world.
The hidden community serves as a crucial plot device, shifting the narrative from a story of individual struggle to one of collective survival. It provides a sanctuary for Melly and Anny Beth, offering support, shared knowledge, and a sense of belonging. This device allows the exploration of how a unique society might function under extraordinary circumstances, with its own rules, hierarchies, and challenges. It also amplifies the stakes, as the threat of discovery now endangers not just two individuals, but an entire way of life. The community's existence is essential for the protagonists to find answers and ultimately embrace their future.
Hidden scientific records revealing the true nature and intentions of the original experiment.
The Project Turnabout logs act as a pivotal 'revelation' plot device. Their discovery provides the critical information that transforms the community's understanding of their condition, specifically debunking the myth of a 'deadly' age zero. This device is essential for resolving the central mystery and shifting the narrative from despair to hope. It exposes the manipulative nature of the original scientists and allows the characters to make informed decisions about their future, ultimately paving the way for the community to embrace the full cycle of 'turnabout' rather than fearing it.
The gradual fading of memories as 'reverses' grow physically younger.
Memory loss is a poignant and terrifying plot device that underscores the profound impact of reverse aging on identity. As Melly and Anny Beth regress physically, their memories of their original adult lives begin to fade, threatening to erase who they once were. This device creates a sense of urgency, driving them to find answers before their minds completely regress. It highlights the psychological toll of their condition and adds a layer of existential dread. The community's efforts to preserve their histories and the poignant moments of forgotten pasts are directly a result of this powerful and emotional plot device.
