I read this with my nine and six year old daughters and can honestly say it was one of the best books I've ever read. My children are so addicted to it that we're now reading the sequel. The depth of description that Aguiar goes into about the extraordinary Tamarind is staggering. Highlights for us were the Cloud Forest Village up in the trees and the character Helix - a wild boy who helps the lost children find their parents on the beautiful but war-torn tropical island. I love the inspired imagination that went into this and wish this book had existed when I was a child.
