Silver stirrups - 65

Carole Hanson is used to being the best junior rider at Pine Hollow Stables. She doesn't need to brag about it, but she takes it for granted, in a quiet, nice way. Then a new rider starts taking lessons at the stables - and she's not only younger than Carole, but also a better rider!
Carole soon realizes that the new girl excels in the saddle, but on the ground she's got a lot to work on. With dread, Carole realizes that she is the best person to help this motherless girl with her problems. But can she forge a friendship with someone she envies? Carole is fighting a battle with jealousy - and it looks like the green-eyed monster is winning!
