Twenty-nine-year-old Blair Walker is a girl with a plan, or more a girl with a list. A list of dos and don'ts to live the perfect life, land a dream career, and marry Mr. Right. But when Blair loses her job and gets dumped by her boyfriend all in one day, she starts to wonder if she's had it all wrong. And what better way to find out than experience everything the list forbade?

• Never Lie
• Never Pick a Fight
• Never Make a Scene
• Never Make the First Move
• Never Make Impulse Decisions
• Never Mix Business and Pleasure

With hilarious consequences, Blair will discover some items are trickier to tick off than she'd thought...

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. There’s only one problem: Molly’s coworker Reid. He’s an awkward Tolkien superfan with a season pass to the Ren Faire, and there’s absolutely no way Molly could fall for him. Right?
