Bone of My Bone. Bloodmoon Cove Spirits, #7

Nestled on Lake Superior in northern Wisconsin is a small, secluded town called Bloodmoon Cove with volatile weather, suspicious folk...and newly awakened ghosts. Don't close your eyes... How to bury what won't stay dead...?When Bennet Ryan was eight years old, he met Ice and fell for her. Yet who Ice was and where she came from was an enigma she adamantly concealed. When they were 19, Bennet demanded she entrust her secrets to him or he'd move on.
Every year since he met her, she'd disappeared at the end of September. After Bennet left her, he'd worried she wouldn't come back within two weeks the way she always had before. His worst fear materialized when she didn't return. Now, at 20, Bennet is the new deputy sheriff in Erie County. Still grieving a year after her disappearance, he's floored when Ice reappears. As they fall in love all over again, September is approaching rapidly.
Bennet is compelled to solve the mystery of Ice. The deeper he delves, the more certain he is that the hole the Mino-Miskwi elders tore in the veil between the living and the dead a century ago has created a maelstrom of twisted horror. How can he possibly save the woman he loves from an entity that wears the name of creation's first murderer, bears an immortal seal, and made a pact with the devil himself?
