Shadow Silence by Yasmine Galenorn

Whisper Hollow, where spirits walk among the living, and the lake never gives up her dead...
Fifteen years ago, I ran away from Whisper Hollow, Washington, a small town on Crescent Lake in the Olympic Peninsula. But truth is, if you were born here, you can never really leave. I'm Kerris Fellwater, and I'm a spirit shaman. It's my responsibility to drive the dead back to their graves, because around Whisper Hollow, people-and secrets-don't always stay buried.
My best friend Peggin finds herself under a curse after she is almost taken by the Lady of the Lake. As Bryan-my guardian and mate-and I work to break the hex, we stumble over a dark and violent mystery from the past. One the Hounds of Cú Chulainn will do anything to stop us from bringing to light.
