Wonder - R.J. Palacio
Meet August Pullman:

"The main thing I have is this thing called man-di-bu-lo-facial dys-os-tosis--which took me forever to learn to pronounce, by the way. But I also have this other syndrome thing that I can't even pronounce. And these things kind of just morphed together into one big superthing, which is so rare they don't even have a name for it. I mean, I don't want to brag or anything, but I'm actually considered something of a medical wonder, you know."

But his medical condition is not what defines Auggie. He is a son, a brother, a good friend, he is obsessed with Star Wars, he is smart, funny--he is just another person. And this is what defines him. Wonder is one of those heavily emotional books that kind of change you, restore your faith in humanity (if you will) and make you love everything and everyone around you.
