Wills is head-over-hoof for horses, and beyond excited when she gets the chance to start training at the prestigious Oakwood Riding Academy. But Amara - the Queen of the #HorseGirls - and her posse aren't going to let the certifiably dork-tagious Wills trot her way into their club so easily. Between learning the reins of horse riding, dealing with her Air Force pilot mum being stationed thousands of miles from home, and keeping it together in front of (gasp!) Horse Boys, Wills learns that becoming a part of the #HorseGirl world isn't easy. But with her rescue horse, Clyde, at her side, it sure will be fun. Complete with comedic, original hoof notes to acquaint the less equestrian among us, Horse Girl delivers everything a young readers wants: mean girls, boy problems, and embarrassingly goofy dad jokes. And it does so on the back of a pony.
