A tech thriller set in a near future in which AIs, both corporate and personal, have become ubiquitous. Julia is a gifted young hacker with a troubled past, trying to put the troubles behind her. A man comes to her desperate for help finding his famous wife who disappeared and may have been kidnapped. The future in this book is very believable, especially in the growth, use, and misuse of AI. It's also very disconcerting. Interesting characters, though some don't feel as fleshed out as they might have deserved. I enjoyed it.
