Gregor and the Marks of Secret

Gregor and the Marks of Secret - Suzanne  Collins It's been years since I read the first three books, and I was struggling to remember what had happened last, so it's surprising I enjoyed this Adam much as I did. Especially with how dark the story has become. Why these books are in the kids section instead of the teens is beyond me. The story is almost as dark as the Hunger Games. Maybe even more with this book's detailed and horrifying descriptions of the genocide of the mice.
