The Truth About Horses, Friends & My Life as a Coward by Sarah P. Gibson
So you think you love horses? That's what Sophie Groves thought too. But she found out that horses are a heap of trouble. Her trials began at five years old when her mom brought home Really (a.k.a. Really Mean), the nastiest pony in Maine. Two horses later, Sophie is still learning to deal with these crafty creatures, while trying to find friends who will like her for who she is-not for her horses. Filled with hilarious horse capers and the real truth about life as a weenie, this laugh-out-loud story shows why a horse isn't always a girl's best friend.
