About This Book

In a world where children vanish without a trace and human authorities hit dead ends, Rylee Adamson is the last line of defense—a Tracker who finds the lost when no one else can. Guardian offers a rare exhale in her relentless story: a hard-earned vacation with the person she trusts most. But for Rylee, even stolen moments of peace have a way of unraveling fast, and what begins as a break from the chaos slides into something darker, stranger, and altogether life-threatening. The emotional pull here isn't just the danger—it's watching a character who carries everyone else's weight finally reach for something just for herself, and seeing what the world does with that vulnerability.

Shannon Mayer writes Rylee with a voice that's sharp without being cold, and this novella-length entry in the series is a reminder of how much texture she packs into a tight page count. The pacing is precise, the banter between characters crackles, and the stakes feel personal rather than world-ending for once—which somehow makes them hit harder. Readers already invested in this series will find Guardian rewards their loyalty with quieter, more intimate storytelling that the longer books don't always have room for.
