Harley in the Sky by Akemi Dawn Bowman

Harley has dreamed of joining the circus as trapeze artist, but her parents, who own a circus, want her to go to college because they think she will be limiting herself if she commits to her dream. Tired of having them ignore her feelings, she runs away to join a rival circus. However, the price of her entry into this new troupe is betraying her family. When things don't go as she excepts, she has to face her dreams and the people she hurt.
