Seventeen-year-old Evie Beckham has always been too occupied with her love of math and frequent battles with anxiety to want to date. Besides, she's always found the idea of kissing to be kind of weird. But by senior year, thanks to therapy and her friends, she's feeling braver than before. Maybe even brave enough to enter the national math and physics competition or flirt back with the new boy. Meanwhile, Evie's best friend, Caleb Covic, has always been a little in love with her. So he's horrified when he is forced to witness Evie's meet-cute with the new guy. Desperate, Caleb uses an online forum to capture Evie's interest—and it goes a little too well. Now Evie wonders how she went from avoiding romance to having to choose between two—or is it three?—boys.
