Armed with a magical cell phone, a heartbroken seventeen-year-old Devi calls her fourteen-year-old self to rewrite past mistakes, only to discover that changing the past might unravel her future in unexpected ways.
Seventeen-year-old Devi is devastated when her long-term boyfriend, Bryan, breaks up with her. She realizes she sacrificed her friendships, academic pursuits, and extracurriculars for their relationship, leaving her with nothing. Feeling lost, Devi accidentally drops her cell phone into a mall fountain. When she tries to use the waterlogged phone, it calls only one number: her own. However, the voice on the other end is not her current self, but her fourteen-year-old self from three years ago. Initially, both Devis are disoriented and disbelieving, with the younger Devi thinking her future self is a prank caller.
After several attempts and much convincing, future Devi makes her fourteen-year-old self, who is just starting high school, believe her story. Future Devi's immediate priority is to prevent past Devi from dating Bryan. She explains how Bryan will eventually break her heart and lead her to neglect everything else. Past Devi, however, is smitten with Bryan and initially dismisses the warnings, finding it hard to believe that the cute, charming boy she likes could cause such future pain. This initial resistance shows how difficult it is to change the past, even with perfect foresight.
Future Devi persists, detailing specific events and feelings that only past Devi would know. Convinced, past Devi follows her future self's advice and actively avoids Bryan. Instead of pursuing him, past Devi focuses on her friendships with Sarah and Alana, joins the school newspaper, and dedicates herself more to her studies. These small changes immediately ripple through her timeline. Future Devi notices subtle shifts in her own present: her memory of her first kiss with Bryan changes, and details about her high school years become fuzzy, showing that the past is indeed being altered.
As past Devi continues to make different choices based on future Devi's guidance, her social life changes. She spends more time with Sarah and Alana, strengthening their bonds. She also becomes closer to Luke, a boy she previously knew but never considered romantically because she was too focused on Bryan. Future Devi learns through their phone calls that past Devi attends prom with Luke, a significant departure from her original timeline where she went with Bryan. These changes delight future Devi, who believes she is successfully crafting a better past for herself.
Future Devi starts to realize that while she successfully removed Bryan from her past, Luke seems to be a more persistent presence. In her original timeline, Luke was a friend who had a crush on her, but she never returned his feelings due to her obsession with Bryan. Now, past Devi is developing genuine feelings for Luke. Future Devi, in her present, finds herself interacting with Luke more frequently, but their dynamic is different. She begins to question if simply avoiding Bryan was enough, or if she inadvertently created new, perhaps more complicated, romantic situations.
As past Devi makes more choices, future Devi's present reality transforms in increasingly significant ways. Her memories shift, sometimes mid-conversation, making it difficult to remember her 'original' past. Her apartment changes, her job prospects vary, and her relationships with friends like Sarah and Alana are different. She finds herself in situations she does not recall, interacting with people in new ways. This constant flux creates disorientation and anxiety for future Devi, as the future she thought she was fixing becomes an entirely new, unpredictable present.
Past Devi and Luke become a couple, much to the initial satisfaction of future Devi. However, the new timeline has challenges. Past Devi and Luke face typical teenage relationship drama, including jealousy and misunderstandings, which future Devi never experienced with Bryan. These new problems show that simply changing the person does not eliminate all difficulties. Future Devi realizes that even with her guidance, past Devi still has to navigate the complexities of life and relationships, and not all outcomes are perfectly 'better'.
The magical cell phone, which is Devi's lifeline to the past, begins to show signs of breaking down. Calls become staticky, connections drop, and the battery drains rapidly. This signals to future Devi that her window of opportunity to influence the past is closing. She realizes she needs to make her final, most important advice count. The impending loss of communication forces future Devi to confront whether she truly improved her life or just traded one set of problems for another, and if she became too reliant on trying to control the past.
In their last coherent call, future Devi gives past Devi her most vital piece of advice: not to rely solely on her future self's guidance, but to trust her own instincts and make her own choices. She emphasizes the importance of balancing relationships with personal goals, maintaining friendships, and pursuing her own interests. Future Devi understands that true happiness comes from within and from making authentic decisions, not from a perfectly engineered past. She encourages past Devi to live fully and learn from her own experiences, good or bad.
The phone finally dies, severing the connection between the two Devis. Future Devi wakes up the next morning to a completely new present, a culmination of all the changes she influenced. She finds herself in a different apartment, with a different job, and with her friendships with Sarah and Alana stronger than ever. Luke is a significant part of her life, but their relationship is established on a different footing than her original past with Bryan. She has memories of a high school experience that is largely positive, filled with personal growth and balanced relationships.
In her new present, Devi eventually encounters Bryan. This time, however, the interaction is completely different. Bryan is still charming, but Devi is no longer captivated or heartbroken by him. She sees him as just another person, without the intense emotional baggage of her original timeline. This encounter is a powerful validation that her efforts to change the past were successful in freeing her from the pain of their original breakup. She has moved on, emotionally unattached, and confident in her choices.
Devi fully embraces her new reality. She realizes that while she set out to fix her past relationship with Bryan, she ended up creating a much more fulfilling and well-rounded life for herself. Her friendships are solid, her career path is exciting, and her relationship with Luke is built on a foundation of mutual respect and genuine affection. She understands that the journey, with all its unexpected twists and turns, was ultimately about self-discovery and learning to trust her own decisions, rather than simply avoiding past mistakes.

The Supporting
Her relationship with Devi strengthens as Devi prioritizes friendship over romantic obsession.
The novel explores how past choices, particularly in relationships, can lead to regret. Devi's initial devastation over her breakup with Bryan comes from her feeling she 'wasted' three years. The magical phone offers her a chance to undo these regrets, but it quickly becomes clear that altering the past has unpredictable consequences. The story shows that every choice, even small ones like joining a club or spending time with friends, contributes to one's future, and that focusing too much on one aspect (like a romantic relationship) can lead to missed opportunities and a sense of loss. Ultimately, Devi learns that some 'mistakes' are necessary for growth.
“What if getting what you think you want changes everything?”
A central theme is the fluidity of time and how changes in the past affect present identity. As Devi advises her younger self, her own present continuously shifts, causing her memories and circumstances to change. This raises questions about what constitutes 'Devi' if her past is constantly being rewritten. She struggles with disorientation as her personal history becomes unstable, showing that identity is deeply intertwined with one's experiences and memories. The story suggests that while one can alter events, the core lessons learned through experience are what truly shape a person.
“It was like watching a movie of my life, but the director kept changing the script mid-scene.”
Initially, Devi believes that her future self holds all the answers and can perfectly engineer a better life. She acts as a guide, telling past Devi what to do. However, as the story progresses, she realizes that constantly relying on external guidance (even from oneself) prevents genuine growth and self-discovery. The new problems that arise in past Devi's life, even without Bryan, show that life's challenges are inevitable. The ultimate lesson is for Devi to trust her own instincts and make her own decisions, rather than trying to perfectly control every outcome. True happiness comes from embracing one's own path, mistakes and all.
“You can't live your life based on someone else's playbook, not even your own future playbook.”
Devi's initial regret comes from neglecting her friendships with Sarah and Alana in favor of her relationship with Bryan. A significant positive outcome of altering the past is the strengthening of these platonic bonds. The novel emphasizes that a fulfilling life requires balance, not just a successful romantic relationship. By prioritizing her friends and personal interests alongside romance, past Devi (and consequently future Devi) builds a more robust support system and a richer, more well-rounded life. This theme shows that diverse relationships and personal pursuits contribute significantly to overall happiness and well-being.
“I’d spent so much time on Bryan, I’d forgotten how much I loved just hanging out with my girls.”
A broken phone that acts as a portal to the past.
The waterlogged cell phone serves as the primary magical plot device, enabling Devi to call her past self. Its malfunction (only calling her past self) is the inciting incident, and its eventual breakdown creates narrative tension and forces a resolution. It acts as a literal 'time machine' for communication, allowing the exploration of 'what if' scenarios without complex scientific explanations. The phone's limited functionality and eventual failure also provide a natural end to the time-altering intervention, preventing an endless loop of changes.
The immediate and continuous alteration of the present based on past changes.
This device is crucial for demonstrating the consequences of Devi's actions. Instead of a single, fixed timeline that she changes and then 'jumps' to, Devi's present reality continuously shifts and changes with each decision past Devi makes. This creates a sense of disorientation and urgency for future Devi, highlighting the unpredictable nature of altering the past. It allows the narrative to explore the 'butterfly effect' in real-time, making the stakes personal and immediate for the protagonist.
The story is told from Devi's immediate perspective, enhancing her disorientation.
Telling the story from Devi's first-person perspective, often in the present tense, immerses the reader directly into her experience of a shifting reality. This choice amplifies her confusion, anxiety, and eventual acceptance as her memories and present circumstances change. It makes her emotional journey more immediate and relatable, allowing the reader to experience the bizarre effects of her time-traveling calls alongside her, rather than from a detached viewpoint.
