From publisher blurb:
The Gulf of the Mun is a treacherous place, its waters thick with legends and the bones of those who dared to sail too far. Maps do not mark the isle, and the stars seem to shift in denial of its existence. Yet, the island is there—lurking beyond the mist, waiting. They call it Xhalthun-Vorr, the Black Moon’s Bastion, a place spoken of only in muttered whispers, where the dead do not sleep, and the living do not stay for long. The storm that carried you here was no accident. You have felt the weight of unseen eyes since you awoke upon the blackened shore, the air thick with an unnatural stillness. Something waits upon this forsaken rock, something that should not be. The symbols carved into the ruins pulse with a malign energy, and in the distance, beyond the skeletal trees and jagged cliffs, the ruins of a forgotten temple stand against the dying light of the moon.
