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!

Daniela came to horse camp all the way from Costa Rica. She’s hoping to become best friends with her cousin Gabriela. But instead, she just feels jealous. Gabriela is the best at everything! Can Dani put her own talents to work and save the day?
