Harper Blaine was your average small-time PI until she died—for two minutes. Now Harper is a Greywalker, treading the thin line between the living world and the paranormal realm. And she’s discovering that her new abilities are landing her all sorts of “strange” cases. A quarter-century ago, the Seawitch cruised away from her dock and disappeared with everyone on board. Now, the boat has mysteriously returned to her old berth in Seattle and the insurance company has hired Harper to find out what happened. But Harper is not the only one investigating.

As they explore the abandoned vessel, Harper and Solis discover a cabin containing symbols drawn in human blood, revealing the ghost ship’s grave history.

And while their searches lead Harper and Solis in different directions, they will need to put aside their differences to solve a deadly mystery twenty-five years in the making…
