Sophie is so excited to arrive at Pony Camp and meet her gorgeous pony, Shine. But her parents have been too busy to take her riding recently and she’s disappointed when she is put in the beginners’ group. Soon, items start disappearing from the girls’ cabin, and Sophie is determined to both ride into the advanced group and catch the thief. But what if everyone suspects that she’s the one who’s been stealing?
