Running With Scissors by Augusten Burroughs
This is an amazing recounting of the author's teenage years. It is funny, shocking, bizarre, sad, strange, unreal, and unbelievable. I can't sum it any better than some of the reviews.
"Written with humor and clear affection for its oddball characters, Running With Scissors is a story of shocking discovery and unlikely survival." - The Onion
"Screamingly funny ... In the end, the book celebrates Burrough's resilient, upbeat spirit, which helps him surmount one of the weirder childhoods on record." -Deirdre Donahue, USA Today
It is one of my favorite books and I recommend it, with caution.
