Books like Margaret Ziegler is horse-crazy by Crescent Dragonwagon

Margaret Ziegler is a young girl who is obsessed with horses. She dreams of owning her very own horse, but her parents insist that she focus on her studies. However, when Margaret learns about a horse riding camp at Country Life Riding Day Camp, she can't resist the chance to finally experience the thrill of the saddle. As she prepares for the event, Margaret's world is turned upside down when her best friend, Emily, announces that she's going to the camp too. The two girls spend their entire weekend at the camp, and Margaret quickly discovers that she has a talent for riding horses. The camp's instructor, Mr. Thompson, becomes a mentor to Margaret and helps her perfect her horsemanship. As the camp draws to a close, Margaret must decide whether her love for horses will overshadow her studies, and she must face the possibility of being unable to ride horses forever. The camp is a chance for Margaret to prove to herself that she can do anything she sets her mind to.
