The Saddle Club is in trouble! Stevie has been picked by Max, the owner of Pine Hollow Stables, to plan some games for its upcoming horse show. And Carole is busy helping the vet care for Delilah, the mare who is soon to give birth to a foal sired by Cobalt, Carole's beloved stallion. Neither of them seem to have any time for Lisa, who's been drawing up an elaborate constitution for the club, including rules for meeting attendance. Lisa is getting tired of being the only one at club meetings! Unless the girls decide to stick together, there won't be any Saddle Club and no fun at Pine Hollow Stables. And isn't that what the Saddle Club is all about?
