Giants of the Frost — Kim Wilkins

Taking a job on an isolated island in the Sea of Norway, scientist Victoria Scott wants a quiet place to finish her doctoral thesis. But Victoria isn't prepared for the strange shadows outside her cabin window, the rumors of a murderous hag who sucks one's soul during sleep, and the tales of mythic monsters lurking in the forest. More frightening than the island's nightmarish mysteries: to Victoria, everything is hauntingly familiar.

When an enigmatic stranger appears on the island, Victoria's sense of foreboding peaks. For she learns that they are connected by a conflict centuries old-one that can end only with her death...
