School is out for the summer, and The Saddle Club has big plans. Lisa, Carole and Stevie have all been invited to Wyoming to work on a ranch and help run a Western riding camp. The girls are looking forward to a great summer of fun and riding until Lisa’s parents break the terrible news: they want Lisa to go with them to Europe for a month. Lisa’s upset and she’ll be missing the chance to work as a ranch hand – how will she survive for four whole weeks without her best friends Stevie and Carole, and horses to ride? And how will Stevie and Carole get on in Wyoming without Lisa?
