A solid mystery with ups and downs. Starts off very strong, with a surreal shock as the heroine sees her dead husband in a nannycam video, then wanders a bit in the middle section as the gradual investigation progresses. It's a first-person novel and our heroine's head isn't a very pleasant place to be, as a war survivor with PTSD. She spends a lot of time being needlessly combative and antagonistic towards people on her side, or people who could help her, to the point that by about 60% through, I just wanted to shake her. However, it picks up as it moves into the final act and the climax and finale is a doozy. 
 Solid entertainment but not something I'd ever be likely to want to revisit.
