A man with no memory must piece together his identity through the fragmented legacy of a previous self, all while evading an unseen, predatory entity that feeds on thoughts and memories.
Eric Sanderson awakens in an unfamiliar house, disoriented and with no memory of his past or identity. He finds a note, seemingly from himself, instructing him to visit a Dr. Randle. The note explains his memory loss is a recurring condition. Following the instructions, Eric makes his way to Dr. Randle's office, a place that feels both strange and vaguely familiar. Dr. Randle confirms Eric's amnesia, explaining it as a symptom of a severe dissociative disorder that began two years prior after the tragic death of his girlfriend, Clio, in the Greek islands. Eric is told he has been under Dr. Randle's care for this period, a revelation that leaves him feeling hollow and disconnected from his supposed past.
Back at the house, Eric explores, finding hidden messages and a collection of documents left by 'the first Eric Sanderson.' These texts, which include letters, diagrams, and cryptic warnings, suggest a far more sinister explanation for his memory loss than Dr. Randle's diagnosis. The first Eric warns of a predatory entity, a 'conceptual shark' known as a Ludovician, that preys on memories and thoughts. This entity is responsible for 'eating' Eric's past. The discovery shatters Eric's understanding of his situation, introducing a world where literal predators of thought exist and his amnesia is not a disorder, but a consequence of being hunted.
Driven by the first Eric's warnings, Eric tries to understand this new reality. He soon meets Scout, a mysterious and resourceful woman who seems to be an expert in navigating the 'conceptual world.' Scout is initially wary but becomes Eric's guide and protector. She explains the Ludovician, a shark-like entity that exists in the conceptual ocean of human thought and memory, feeding on minds. She introduces him to 'conceptual energy' and how certain objects and places can be imbued with it, making them dangerous or useful. Scout also reveals that the first Eric Sanderson had been researching these phenomena extensively, leaving a complex trail for the current Eric to follow.
As Eric looks deeper into the first Eric's research and Scout's explanations, he begins to experience the tangible effects of the Ludovician's pursuit. He feels dread and emptiness, and his memories continue to fragment. Objects around him sometimes display strange, ephemeral effects, hinting at the conceptual world bleeding into reality. These encounters escalate, culminating in direct attacks where the Ludovician's 'presence' is almost physical, causing disorientation and further memory erosion. These terrifying experiences solidify Eric's belief in the conceptual shark, confirming that he is indeed being hunted and that his identity is at stake.
Through the first Eric's notes and Scout's insights, Eric uncovers the true story of Clio, his lost love. He learns that Clio was not merely a victim of a tragic accident but was deeply involved in the conceptual world, possibly even possessing an innate connection to it. Her death was not accidental but a consequence of her research or involvement with these hidden forces, perhaps even a sacrifice. The first Eric's quest to understand and avenge Clio led him to the 'underwater library'—a conceptual space where memories and knowledge are stored, and where Clio's remaining essence might reside. This revelation changes Eric's amnesia from a personal tragedy into a piece of a larger, cosmic mystery directly linked to Clio.
With a clearer understanding of Clio's fate and the threat of the Ludovician, Eric, guided by Scout, embarks on a dangerous journey. Their quest involves navigating various 'conceptual spaces'—places where the boundary between physical and mental reality blurs. These spaces are often represented by physical locations imbued with significant meaning or conceptual energy, such as a specific bookstore or a forgotten alley. They use the first Eric's meticulously crafted 'conceptual maps' and 'conceptual weapons'—items designed to interact with the conceptual world. Their journey is fraught with danger, as the Ludovician continues its relentless pursuit, forcing them to constantly adapt and use their wits to survive its attacks.
During their journey, Eric and Scout encounter the Mycroft, a benevolent conceptual entity described as a 'conceptual cat.' Unlike the predatory Ludovician, the Mycroft is a creature of information and connection, capable of navigating and understanding the intricate pathways of the conceptual ocean. The Mycroft recognizes Eric's unique connection to the first Eric and Clio. Sensing his pure intentions, it becomes a powerful ally. Its presence provides crucial guidance and protection, offering insights into the Ludovician's weaknesses and the nature of the conceptual world that Eric and Scout desperately need to continue their quest and confront the conceptual shark.
Armed with new knowledge and the Mycroft's assistance, Eric and Scout prepare for a final confrontation with the Ludovician. Their path leads them to the deepest parts of the conceptual ocean, specifically the conceptual underwater library where Clio's fragmented consciousness is believed to be held. The battle is not physical but a clash of wills and conceptual energy, with Eric using the first Eric's 'weapons' and his own growing understanding of the conceptual world. The goal is not to destroy the Ludovician outright, but to retrieve Clio's essence from its grasp, a delicate and dangerous operation that risks Eric's remaining memories and sanity.
Following the intense confrontation, Eric is profoundly changed. He has not fully recovered all of his original memories, but he has integrated the experiences of both the original Eric and his own journey. Clio is partially recovered, existing in a new, conceptual form, a sign of the enduring power of their love. Eric now possesses a unique understanding of the conceptual world, a blend of his past self's knowledge and his current self's experiences. He is no longer just a victim of amnesia but a survivor and a new kind of being, forever altered by his encounter with the Ludovician and his quest to reclaim Clio. He has found a new purpose in understanding and navigating the conceptual ocean.
In the aftermath, Eric and the partially recovered Clio learn to live in their new reality, understanding that their existence is now linked to the conceptual world. Clio, in her fragmented but sentient conceptual form, remains a constant presence, a living embodiment of the struggle and triumph. Eric continues to explore and understand the conceptual ocean, using the knowledge from the first Eric and his own experiences to navigate its complexities. Their journey is ongoing, a sign of enduring love and the resilience of the human spirit in the face of the incomprehensible. They find a new kind of peace, accepting their changed forms and their place within the vast, unseen ocean of thought.

The novel explores how memory shapes identity. Eric's amnesia initially leaves him a blank slate, showing that without memory, a person loses their sense of self. The Ludovician's consumption of memories literally erases who Eric is. The first Eric's plan to restore memory highlights its importance. The journey to reclaim Clio's fragmented consciousness also speaks to memory as the essence of a person, even beyond physical form. The book suggests that identity is not static but an evolving narrative built from our experiences and recollections.
“What is a man without his memories? A ghost, a shadow, an echo.”
Love, particularly the love between Eric and Clio, drives the narrative. Clio's 'death' and the subsequent grief are the catalysts for both Eric's initial amnesia and the first Eric's research into the conceptual world. Eric's entire quest is motivated by his love for Clio and his desire to rescue her, even in a fragmented, conceptual form. The story portrays love as something that transcends physical existence and even memory, remaining a powerful, motivating force against the ultimate predator of the mind. Loss is depicted as a wound so deep it can reshape reality.
“Love is the only language that can cross the conceptual divide.”
The novel posits the existence of a hidden 'conceptual ocean' that underlies our perceived reality, populated by entities like the Ludovician and Mycroft. This theme challenges conventional notions of reality, suggesting that what we experience is only a fraction of what truly exists. The 'raw shark texts' themselves are a form of conceptual communication, showing that information and thought can have a tangible, predatory, or benevolent existence. The book invites readers to question the boundaries of the known and consider the vast, unseen forces that might influence our minds and lives.
“There are oceans beneath our minds, and things swim in them.”
Eric's journey is a desperate fight for self-preservation, not just physically, but existentially. The Ludovician threatens to erase his very being, forcing him to confront the fragility of his existence. Beyond mere survival, Eric seeks meaning in his fragmented life and in Clio's fate. His quest to understand his past and reclaim Clio is a search for purpose and an assertion of his will against the forces of oblivion. This theme highlights the human drive to create meaning even in the face of overwhelming, incomprehensible threats.
“To be forgotten is to truly die.”
Eric's memory loss initiates the mystery and his journey.
Eric's amnesia is not merely a plot point but the central mystery from which the entire narrative unfolds. It prevents him from understanding his situation, forcing him to rely on the 'first Eric's' clues and Scout's explanations. This device allows for a gradual reveal of the complex conceptual world, as Eric (and the reader) learns alongside him. It also heightens the stakes, as his very identity is vulnerable to the Ludovician, making his quest for memory a fight for his selfhood.
Conceptual messages and diagrams that reveal the hidden world.
The 'raw shark texts' are the primary method through which the first Eric communicates with his future self and the reader. These are not conventional written documents but often include diagrams, specific word patterns, and even conceptual 'traps' designed to convey information about the Ludovician and the conceptual world. This device is highly creative, mirroring the conceptual nature of the story, and serves as a literal 'map' for Eric's journey, making the act of reading the book itself an immersive experience that blurs the lines between fiction and reality.
Personified forces that interact with the conceptual ocean of thoughts and memories.
The conceptual entities, primarily the Ludovician and Mycroft, are personifications of forces within the conceptual ocean. The Ludovician embodies conceptual predation and entropy, literally 'eating' memories. Mycroft, in contrast, represents conceptual connection, knowledge, and guidance. These entities provide tangible antagonists and allies in a world that is otherwise abstract, giving the conceptual realm a sense of living, breathing danger and potential aid, making the struggle more immediate and relatable despite its fantastical nature.
A past self who meticulously prepared for the current Eric's arrival.
The 'first Eric Sanderson' is a brilliant manipulation of narrative perspective. He is not a separate character but a past iteration of the protagonist, whose foresight and meticulous planning drive the current Eric's actions. This device creates a unique form of self-mentorship, as the protagonist is guided by his own past intellect. It adds layers of psychological depth and mystery, as the current Eric must piece together the motivations and knowledge of his previous self, effectively making him a detective of his own lost life.
