In the first of two companion mystery novels, the girls of The Saddle Club go to one of their favorite places—Moose Hill Summer Camp. This time they're staying for an entire month!
Right away, the girls start to wonder if their dream summer won't be all they hoped. Lisa learns she's in a different cabin than her best friends, Stevie and Carole. Stevie's boyfriend, Phil, ignores her. Worst of all, Carole is assigned a camp horse that simply won't cooperate. Whoever would have thought this horse-crazy girl would meet an equine she didn't like?
Then, the girls run into some ominous signs that someone wants to close down Moose Hill Camp forever. Can they find out who, before it's too late?
