Zoe Cain knows that Grant Evertide, her brother’s number-one nemesis, is way out of her league. So naturally, she kisses him. She’s thrilled when they start dating, non-exclusively, but Zoe’s brother claims Grant is trying to make her his “Ringer,” an oh-so-charming tradition where a popular guy dates a non-popular girl until he hooks up with her, then dumps her. Zoe threatens to neuter Grant with hedge clippers if he's lying, but Grant swears he isn’t trying to trick her. Still, that doesn’t mean Grant is the commitment type—even if winning a bet is on the line.
