Check out the first title in Books for Young Readers' great new series, Pine Hollow, by Bonnie Bryant, author of the popular series, The Saddle Club:

Stevie Lake, Lisa Atwood, and Carole Hanson are best friends, and they share everything--including their love of horses. Now that they are in high school, they are as busy as ever. Stevie is spending more time on her car than her horse; Lisa is struggling to make her long distance relationship work; and Carole is so busy with her job and the horses she works with that she ignores the people around her! Then a terrible accident leaves a girl's life in danger. Will the strain these friends are facing be too much to keep their friendship alive?
