Wonder by R J Palacio

I won’t describe what I look like. Whatever you’re thinking, it’s probably worse. 
August Pullman was born with a facial difference that, up until now, has prevented him from going to a mainstream school. Starting 5th grade at Beecher Prep, he wants nothing more than to be treated as an ordinary kid—but his new classmates can’t get past Auggie’s extraordinary face. Wonder, begins from Auggie’s point of view, but soon switches to include his classmates, his sister, her boyfriend, and others.
