Riding Academy. The Secret of Cherokee

Mariana's roommate, Agnes, works wonders in vaulting with Cherokee – her horse, which she chose herself and loves with all her heart. But the trouble is that Cherokee only performs everything correctly when there are no spectators. In public, the horse gets nervous and forgets everything they practiced in private. This could jeopardize their participation in the long-awaited New Year's performance.
Agnes, along with her loyal friends, is trying to unravel the mystery of Cherokee's skittishness. Perhaps the answer lies in his past?
