Detective Roman Stone is working hard to rebuild the career he nearly destroyed.
When he gets called to Alexandria Bay, NY to help the small town police force find a popular missing teenager, random human bones start washing up on the shores of the St. Lawrence River and one simple case becomes the the biggest mystery of his life.
Chasing clues leads Roman to local historian Becca Quinn, who is the only one willing to show him around the old castles in the area. Becca heads up the Thousand Island Preservation Society and spends her days working to restore some of the island mansions for a new tourism initiative. The last thing she expects is to become part of the investigation, and for her life to be in danger.
What they find is something no one could imagine…
Something strange is lurking under the murky surface of the river waters, and a powerful local family is hiding secrets that could unravel the entire mystery.
