School's out, and three horse-crazy best friends promise to have the best summer ever Before Lisa Atwood, Stevie Lake, and Carole Hanson become high school juniors in the fall, the girls have a busy summer ahead. Lisa is spending every waking minute with her boyfriend, Alex--who's also Stevie's twin brother--until she leaves to visit her dad and his new family in California. Stevie just got her driver's license, and when she isn't delivering pizza, she's hanging out with her boyfriend, Phil Marsten. And Carole is working long hours at Pine Hollow Stables--for the horses and for Ben Marlow, the mysterious stable hand who's just as horse crazy as she is. But everything changes when the new girl arrives in town with a champion horse in tow. Will Lisa, Stevie, and Carole's friendship ever be the same again?
