Charlotte has made it into the prestigious Junior Olympic Equestrian Squad (JOES), and Leila is having so much fun with Charlotte that she’s given up her sparkling Hollywood movie career, for now. The Evil Three, Emma, Lucinda and Rebecca, are back to make Charlotte’s life difficult. Luckily, Charlotte finds a friend in Hannah, a new JOES recruit. But this means she has less time to spend with Leila - and Leila is a horse who doesn’t like to be ignored. Unfortunately, things get a whole lot worse when Charlotte is sent to a deportment academy, and she returns to Thornton Downs to discover Leila has been sold to a disreputable showman. Charlotte has to get Leila back, but it will take all her courage and brains, as well as help from Todd and Hannah, to rescue her best friend.
