A suspicious death. A long-buried betrayal. A summer that changed everything.

 

In 1999, Elle Cavanaugh thought she knew exactly who she could trust. During one unforgettable summer at Mirror Lake, she and her closest friends stood on the edge of adulthood, bound by friendship, first love, and promises that felt unbreakable.

 

But one confession, one betrayal, and one devastating choice would alter the course of their lives forever.

 

More than twenty-five years later, Elle is grieving the loss of her husband, Seth, when troubling discoveries begin to surface. A secret meeting captured on security footage. A hidden safety deposit box. Missing money converted into cryptocurrency. As questions surrounding Seth's death multiply, the answers seem to lead back to the people who have been part of her life from the very beginning.

 

Then there's Jack, a newcomer who  offers a welcome distraction from her grief. But when Elle realizes he may have his own reasons for being in Stillwater, she begins to wonder whether his arrival was ever a coincidence.

 

As past and present collide, old loyalties are tested, hidden motives emerge, Elle must confront the possibility that those closest to her have been lying all along.

 

Behind the glassy surface of Mirror Lake lies a dark story of love, betrayal, and broken friendships. Once Mine is a sharp modern noir driven by Elle—a messy, relatable protagonist dealing with grief and a knack for making bad decisions. Readers will love her sarcastic wit as she turns amateur sleuth to dig up a small town's darkest secrets.
