Rachel and her Bridesmaids are enjoying their bachelorette party in Vegas. The lights of Las Vegas screamed sin, and the girls were already two margaritas past tipsy when they stumbled out of the limo. “Okay, ladies,” Rachel called out, holding up a glittering sash that read Bride-to-Be. “Tonight is about bad decisions and good stories. No regrets!” The group of six women—former sorority sisters, now office workers, teachers, realtors, and mothers—cheered like they were eighteen again. They were loud. Buzzed. High on neon and freedom. A simple dare changes all their lives.
