The book is about which relationships matter. Ben's dad is a cold guy who treats Zan like the object of an experiment, not a living creature, which infuriates Ben. He already wonders what's more important to his father, the project or his own son. Ben's also trying to fit into a ritzy private school where he's making some not very smart decisions about how to make friends with the cool kids. Oppel's plainly done a whack of research on primates and their abilities, and the animal rights twist in the tale gives it real urgency. A very engaging read and not for young adults only.
