Four lifelong friends, inseparable since high school, reunite at their 30th class reunion - and discover that thirty years apart hasn't changed a thing between them. As the weekend unfolds, they hatch a plan for the adventure of a lifetime: a two-week European vacation to celebrate turning fifty together.
On their first night in Rome, Cindy has one birthday wish - that they play the childhood game they used to love, pretending to be someone else for a while. Mary, a romance writer working on a new book about their trip, spins it into something even better: they'll be the Bachelorette Sleuths, fictional characters hunting an international jewelry thief aboard their cruise ship.
It's all just a fun game... until it isn't. When the ladies unknowingly catch the attention of a real jewel thief - one with Interpol on his trail and a plan to use them to smuggle his latest score - the childhood game they never stopped playing becomes the very thing that saves their lives.
From the sun-drenched streets of Rome to the open waters of the Mediterranean, this is a story about the friendships that carry us through every season of life - and the courage it takes to trust your gut, even when you'd rather look away. A heartfelt story of friendship, faith, and the adventures that remind us we're never too old for one more chapter.
