Charlotte has made it into the prestigious Junior Olympic Equestrian Squad and Leila is having so much fun with Charlotte that she's given up her sparkling Hollywood movie career for now. Charlotte has also made a friend in the new recruit Hannah, but this means she has less time to spend with Leila - and Leila is a horse who doesn't like to be ignored! Things get a whole lot worse when Charlotte returns from an academy to discover that Leila has been sold to a disreputable showman. Charlotte has to get Leila back, and it will take all her courage and brains as well as help from Hannah to rescue her best friend.
