I enjoyed this book, about a girl who discovers her parents are actually aliens living on earth to observe our culture. When they suddenly need to go home, they tell her the truth, and the book is about how she deals with that new knowledge.
I realized about halfway through this book is a sequel, and parts of it were disjointed because of that fact, more than I think were necessary. It's great to have sequels, but I think books need to stand on their own too, without characters dropped in without a lot of explanation. I also found some of the reactions of characters to huge events oddly muted, but that might be because they are all British!
