Rule #1: Don't spill crab cakes on a billionaire. Rule #2: Definitely don't fall for him when he's buying an engagement ring for someone else. Emma Valentine broke both rules in one night. As a foster kid turned struggling artist working three jobs, Emma has perfected invisibility. She serves champagne to Manhattan's elite and dreams of a gallery she'll probably never afford. Then Sebastian Wolfe walks into her jewelry store, and for one electric moment, she feels seen . Hours later, she dumps appetizers all over his Tom Ford tuxedo—at his fiancée's birthday party. In front of 500 guests. While he's supposed to be proposing. She's mortified. He's mesmerized. And neither can forget what sparked between them. But Sebastian's engaged to Manhattan royalty, his family expects him to propose, and Emma knows fairy tales don't happen to girls like her. When he shows up at her door the next day, card in hand and that devastating smile on his face, Emma faces an impossible choice: protect her heart or risk everything for a love that could destroy her. Some collisions ruin your night. Others change your life.
