"A surprising gem."

"Incredible, timely, and thought-provoking."

"Thrilling mystery and philosophical mind-bender... an ethical tour-de-force."

Raphael is the holy grail of AI: a superintelligent robot that's been programmed to be the perfect moral being. Or at least that's what Andy, its creator, believes.

But when an accident forces Andy to stay home, he learns that the robot has disappeared from its lab, mysteriously bypassing a sophisticated security system and the cognitive "laws" supposed to keep it in check. Besides, the robot has never been in the outside world; will its programming hold or will it unravel, releasing some Frankenstein's monster that was always lurking underneath?

Confined to a wheelchair, under siege by a parent company hiding its own dark secrets, Andy is about to find out. At his remote and secluded mansion he has something the robot desperately needs... something that can erase its moral programming once and for all.

And make no mistake, Raphael is coming for it.
