The Salt Kiss Rite

From publisher blurb:

In the distant cold-clawed outlands of Hjeldholm, where the sky hangs low and leaden like a blade waiting to fall, tales spread in cracked whispers of a cult older than the snows — a communion of murderers and feasters of flesh, cloaked in crimson robes and ancestral sorrow. The hearth-fires in Hjeldholm's mead-halls flicker low when their name is spoken: The Devourers of the Maw. You are a stranger in this land — or perhaps a forgotten son returned — drawn by the call of something too terrible to name. Beneath mountain-shadow and beside the frozen fjords, something ancient stirs in blood and darkness, and it is hungry.
