Vin, a down-on-his-luck young tech entrepreneur forced out of the software company he started, takes a job house-sitting an ultra-modern Seattle mansion whose owner has gone missing. There he discovers a secret basement lab with an array of computers and three large, smooth caskets. Inside one he finds a woman in a state of suspended animation. There is also a dog-eared notebook filled with circuit diagrams, beautiful and intricate drawings of body parts, and pages of code. When Vin decides to enter one of the caskets himself, his reality begins to unravel, and he finds himself on a terrifying journey that raises fundamental questions about reality, free will and the meaning of a human life.

But as two best friends discover, the light of that miracle may be blinding the world to its horrors. Chance and Leap are jolted out of their professional routines by a terrifying stranger --- a remorseless killer who freely manipulates the networks that regulate life in the post-Join world.
