Trish Everett is thrilled to have a chance to spend the summer racing the family sailboat on Sand Lake. But she lives up to her reputation as "Terrible Trish" when she bumps into another boat and is disqualified from her first race! She's ready to give up—until gorgeous Jonathan Stewart offers to show her the ropes. Jonathan can't resist a challenge, and he proves to be a terrific teacher. Trish has never sailed so well - or liked a boy so much. But she can't help wondering if Jonathan will still be around after "Terrible Trish" becomes a winner.
