The State of Grace, by Rachael Lucas
"Sometimes I feel like everyone else was handed a copy of the rules for life and mine got lost."
Grace is autistic and has her own way of looking at the world. She's got a horse and a best friend who understand her, and that's pretty much all she needs. But when Grace kisses Gabe and things start to change at home, the world doesn't make much sense to her any more.
Suddenly everything threatens to fall apart, and it's up to Grace to fix it on her own.
"Grace’s keen sense of humor and honesty are irresistible, and the book exudes positivity and warmth, with a whole crew of individuals―Grace’s family, Anna, ever-patient Gabe, and stable-owner Polly―respectfully walking alongside Grace."--Publishers Weekly, starred review
