I'm more of a fan of Jance's other series, but enjoyed this book. The reliance on AI for cybersecurity is always a bit of a cheat to me--it feels less suspenseful and exciting than old-fashioned investigating, but this time around it didn't bother me much. There are two storylines here, and I kept waiting for them to overlap or entertwined, but they really don't. The main story is about B. Simpson's ex-wife, who is the main suspect in her current husband's murder. I figured out who was behind it pretty quickly, but there were enough twists and turns to keep me interested. It was a bit too slight for my tastes, but this is a quick, enjoyable read.
