I love Kenneth Oppel, but I had issues with this book. It's written for a young adult audience and it raises some legitimate questions about animal rights and about using animals for experiments (even psychological experiments). It is set in the 1970's, though, and some of the issues are no longer as relevant as they once were. For example, no researcher would be allowed to conduct an experiment in his own home with his own family as co-researchers.

On the surface, this is a book about killing zombies. More than that, it's a story about what it means to be human in an imperfect world. The main character, Benny Imura, is challenged to discover the "truth" about his heros, his friends, his brother, himself and -yes - about zombies.
