Time Capsule follows the Senior year of a set of twins, Alexis and Adam. Their lives are going as smoothly as possible, even though their mother is never home and Alexis suspects her father of having an affair, until Adam collapses from the leukemia that had plagued him in the past.This was an interesting book, though not quite a "wow"er. I can't say the sad part was effective enough for me, since I didn't shed a tear (which is unusual for me). However, still a great book and I reccommend it.
