Hannah's Bright Star (Charmed Life #4‪)‬

Four best friends, one lucky bracelet, and an utterly charming new middle-grade series!It's finally Hannah's turn to wear the lucky charm bracelet -- and not a moment too soon! When Hannah got home from summer camp, her parents had a surprise for her. She thought it might be her dream come true: a horse of her own. Instead, her parents got her a mule! Everyone says she can still ride the mule, even for 4-H competitions at the state fair, but how silly will that look? Hannah is so embarrassed, and she needs the support of her Cabin 7 BFFs more than ever!
