Margot Cooper doesn’t do relationships. But now her entire crew has found "the one" and she’s beginning to feel like a fifth wheel. While touring a wedding venue with her engaged friends, Margot comes face-to-face with Olivia Grant—her childhood friend, her first love, her first… well, everything. It’s been ten years, but the moment they lock eyes, Margot’s cold, dead heart thumps in her chest. However, a wedding planner job in Seattle means a fresh start and a chance to follow her dreams. Never in a million years did she expect her important new client’s Best Woman would be the one that got away. When a series of unfortunate events leaves Olivia without a place to stay, Margot offers up her spare room because she’s a Very Good Person. As they spend time in close quarters, Margot starts to question her no-strings stance. Olivia is everything she’s ever wanted, but Margot let her in once and it ended in disaster. Will history repeat itself or should she count her lucky stars that she gets a second chance with her first love?
