“You thought you knew pleasure before you met me. You were wrong.”

Kit Fox needs a fresh start. Her essays on quantum physics are too outlandish for the mainstream, and her writing career is fizzling. But things look up when she’s offered the opportunity of a lifetime: a private three-day interview with reclusive billionaire Ian De Leon, inventor of the Pleasurebot. He’s publishing a biography, and he wants Kit to write it.

But Ian has a secret locked away in his sky-high penthouse: the Prototype, a disobedient and unpredictable new Pleasurebot. Against Ian’s explicit wishes, Kit becomes completely enraptured by the Prototype. And what she thought was going to be a standard interview becomes a sickening freefall into obsession, self-discovery, and otherworldly desires.
