In a world where nothing can be trusted, their love is the only equation that must hold true.
A detective who trusts only what he can punch. A theorist who sees only patterns. Their only weapon is each other.
When a pragmatic architect-turned-detective John Traynor is called to a locked-room mystery, he finds a death with no cause and a crime scene with a single, impossible flaw: the walls are no longer parallel. The only person who understands his discovery is Dr. Elara Vance, a brilliant but dismissed historian of science whose life's work on a forgotten theory of reality is the only key to the truth.
They uncover a terrifying conspiracy orchestrated by the enigmatic Silas Thorne and his secretive order, The Harmonists. Thorne hasn't just discovered the secret to altering human perception—he has built a machine to do it. He can edit reality itself, making enemies doubt their own minds into surrender or death. He calls it perfection. John and Elara call it a weapon.
Now, their greatest threat isn't a bullet; it's a glitch in their own senses. As they are hunted through a city that can no longer be trusted, they must learn to rely on each other. John must embrace Elara's terrifying theories, and Elara must trust John's instinct for action if they are to storm the heart of the machine and stop Thorne from imposing his Grand Harmony upon all of humanity.
PARALLELISM is a mind-bending thriller perfect for fans of Blake Crouch's Dark Matter, the intellectual puzzles of Dan Brown, and the psychological horror of The Twilight Zone.
