Keep your enemies close and your frenemies closer. Seventeen-year-old Samantha Baughman must raise her GPA or she can kiss the basketball scholarship to her dream college goodbye. Getting a trig tutor is complicated because the best person for the job happens to be her nemesis, Samuel King, the school bad boy—and a closet genius. To avoid being sent to alternative school for his recent rule breaking, Samuel agrees to help. But to keep his image intact, nobody else can know, especially Samantha's brother who gave specific instructions to stay away from his sister—or else. As Samuel and Samantha spend more alone time together, their playful banter turns into a real attraction, leading to the world’s hottest kiss. But threats from her brother give Samuel cold feet, and he tells her to forget it happened. To save face, Samantha concocts a story about a glorious encounter with a mystery man in a dark closet, setting her friends off on a “who-dunnit” wild goose chase to uncover the kisser. Coming clean about the kiss might lead to physical injury but keeping it a secret may cost Samuel any chance with Samantha. Yes, she needs his help to pass trig, but he’s the one who needs schooling in matters of the heart.
