So over My Head — Jenny B. Jones

Bella trades her Manolos for clown shoes in order to unravel the secrets of the big top and the drama of high school.

Fresh from saving the prom from a disastrous end, Bella--the amateur sleuth of Truman High--is ready to relax with her new boyfriend, Luke. Or so she thought.

When Luke's ex shows up, Bella has to wage a full-scale war to win him back. Her father is moments away from saying I do to a diva with shady motives. And a murdering magician has disappeared, leaving Bella dangling on a tightrope of one crazy adventure after another. Can Bella stop a wedding, win back the boy, and catch a killer before he strikes again?
