While I prefer books that feature only one case, this one was very interesting. All of the cases featured in this book really serve as an eye opening reminder of what can happen. It is sad that people must always be hypervigilant about everyone around them, but that is the world that we live in. It also serves as a reminder that just because a place seems picture perfect, it doesn't mean it is. Creeps are everywhere. This was a decent book, and I am glad that I found it on sale.
