Seventeen-year-old Molly Peskin-Suso knows all about unrequited love—she’s lived through it twenty-six times. She crushes hard and crushes often, but always in secret. Because no matter how many times her twin sister, Cassie, tells her to woman up, Molly can’t stomach the idea of rejection. So she’s careful. Fat girls always have to be careful.

Then a cute new girl enters Cassie’s orbit, and for the first time ever, Molly’s cynical twin is a lovesick mess. Meanwhile, Molly’s totally not dying of loneliness—except for the part where she is. Luckily, Cassie’s new girlfriend comes with a cute hipster-boy sidekick. Will is funny and flirtatious and just might be perfect crush material. Maybe more than crush material. And if Molly can win him over, she’ll get her first kiss and she’ll get her twin back.
