About the book:

Carly, Daniela, Gabriela, and Kianna – the Pony Girls are ready for their first summer at Storm Cliff Stables! In these four books, each girl has the chance to narrate her own story. Their unique personalities come through as they navigate being away from home, making friends, and caring for the horses at camp. Readers new to chapter books will love this entry into the world of Storm Cliff Stables, with larger text, fewer words, and younger girls in the same wonderful setting!

Carly’s always getting in trouble. But when she finds an injured garter snake, she’s sure she’s responsible enough to care for it. Will keeping her wild pet a secret get her in the biggest trouble of all?
