Y.O.L.O - You Only Live Once Carter Jones, a straight-A student who has never broken a rule before, and Killian Henderson, the school's troublemaker, end up in detention together. Carter notices the tattoo on Killian's knuckles. Y.O.L.O. "You like it?" Killian smiled, flipping his hand so I could get a better look. "It's my life's philosophy." I scowled.
