That wasn't it for me. The premise is interesting, but I learned that I loath books that are about shootings. This one was kind of boring and not much happened except for a woman with her child in a zoo. I was so annoyed with her point of view 80% of the time. The other perspectives were interesting but also useless. They didn't add anything to the story at all. If I hadn't read this as an audio book I would DNFed it.
