Total Constant Order by Crissa-Jean Chappell
Fin can't stop counting. She's always heard a voice inside her head, ordering her to listen, but ever since she's moved to the Sunshine State and her parents split up, numbers thump like a metronome, rhythmically keeping things in control. When a new doctor introduces terms such as "clinical depression" and "OCD" and offers a prescription for medication, the chemical effects make Fin feel even more messed up. Until she meets Thayer, a doodling, rule-bending skater who buzzes to his own beat—and who might just understand Fin's hunger to belong, and her struggle for total constant order.
Crissa-Jean Chappell's candid and vividly told debut novel shares the story of a young teen's experience with obsessive compulsive disorder and her remarkable resolve to find her own inner strength.
