The Fire Eternal. Book 4

Five years have passed since David Rain, now a cult author, disappeared mysteriously in the Arctic. Life in Wayward Crescent has settled to relative normality. But as the weather grows wild and the ice caps melt, all eyes turn north, where bears and the souls of the Inuit dead are combining to produce a spectacular solution... A solution with its focus on David's child, Alexa - if the agents of evil don't reach her first.
