Query: Julian F Thompson is a true genius

GofG6 is a book that I have owned since I was 15 years old and it has moved with me across six states and 15 years. I read it every several years and it is an amazing story no matter what your age. Julian captures teenagers the way they really are, and at the same time tells a story that is spellbinding, funny and very satisfying no matter how many times you read it (or how old you are when you do). His character development is a joy. I can't recommend it enough. If you are lucky enough to find a copy -- buy it!
