The Ultimate Teen Book Guide - Daniel Hahn, Susan Reuben, Leonie Flynn Loved it. Short but useful descriptions on every book and the recommendations at the side kept me in reading material for the past few years. Possibly the best book guide ever, at the very least the best one I've ever come across (and I've come across quite a few). Such a beautiful array of titles from all genres and to suit all ages, I loved scouring this book for hours to decide what I should read next. A teen must-have.
