I really enjoyed the first section of the book about the main character's grandparents - they were so vividly drawn and so sympathetic. The parents were two-dimensional comparatively. I couldn't picture them at all, and since I read it a while ago, I have trouble now bringing even their main points to mind. The only other parts that sparked my interest were scenes from Cal's adolescence. They felt urgent and fraught and very real. Curiously, I found the sections written in the present completely lacking in suspense, even though it was supposed to deal with the question of Cal's future. Overall though, I felt the writing in the good parts good enough to offset the spottiness of the rest.
