Lily Monroe has the perfect itinerary for her best friend’s wedding. Sleeping with the bride’s intimidating, untouchable older sister was definitely not on the schedule. At twenty-four, Lily is the ultimate people-pleaser. As maid of honor, she’s determined to give her best friend the flawless wedding week she deserves. But when a disastrous bachelorette party leads to a tequila-fueled, earth-shattering night with Victoria Hale, Lily’s carefully curated world is thrown into gorgeous chaos. Tori Hale is thirty-nine, a high-powered corporate litigator, and a woman who protects her heart behind an impenetrable wall of ice. She doesn't do messy. She certainly doesn't do twenty-four-year-old bridesmaids. But Lily’s relentless warmth and chaotic sunshine break through Tori's defenses in ways she never saw coming. As the wedding day approaches, their secret hotel-room hookups blur the line between a wedding-week mistake and a soul-deep connection. Tori is terrified of risking her carefully guarded life, and Lily refuses to be anyone's dirty little secret.
