About the book:

It’s a new year at horse camp for new Pony Girls! Charlie, Gracie, Paisley, and Zoey narrate their own stories as they navigate anxiety, learn about caring for animals, and take photos for the camp newspaper. Readers new to chapter books will love this look into the world of Storm Cliff Stables, with larger text, fewer words, and younger girls in the same pastoral setting!

Gracie is finally old enough to come to Storm Cliff Stables! Unfortunately, she gets in some trouble when she keeps revealing people’s secrets. She finally learns to keep them to herself, but soon she has to decide whether to share private information that might keep a friend safe.
