Unexpectedly good- I don't usually read this genre of book (science fictionish) (yes that's a word) (I think) but this story kept me reading until I had finished it. It's a rollercoaster of a book, and I cried heaps, and I definitely recommend it to other people. Sightly mature content, so perhaps a book for older teens, although all cursing is blacked out (which was rather amusing at certain points).
