Olivia Winters has it all—an amazing condo in the city, great friends, and a successful bakery she built from the ground up. The one thing she can't seem to get right is love. With one disastrously bad date after another, she goes cold turkey, giving up men and dating in one fell swoop. The only snag in this plan is the abundance of weddings she now has to go to—alone. But she'd rather do that than suffer through even one more disastrous date.

Ian Donnelly has been in love with his sister's best friend for years. He even moved away after college to try and get some distance from her and the feelings she wasn't even aware she stoked in him. After standing on the sidelines for so long, he impulsively decides to take a chance and offers to be Olivia's plus one for the summer, without fully considering what might come next.

Olivia's never looked twice at her best friend's brother. She doesn't expect intense sparks to fly between them, or for them to fall into bed. She definitely doesn't expect Ian to confess his feelings for her. She's content with keeping things physical between them—after all, her track record in relationships isn't exactly glowing. But will he be satisfied simply being her bedmate and her sometimes plus one?
