It all starts when an anti-whaling ship rams a whaler off the coast of Greenland and the whaler, instead of turning the other cheek, rams it right back, rather more disastrously. But then the whaler explodes.
How? Why? What happened?
Read it and see. Then follow the adventures of the few survivors on a frozen island inhabited by "draugre", Viking revenants - zombies under another, older name.
I liked the narrator, Jane Harper, a real kick-ass ex-military-brat, who responds with a sarcastic quip to everything Greenland and the paranormal can throw at her, but I have to say that while I found the story and the setting exciting I didn't really get any feeling of "horror" - as promised in the subtitle.
As a horror story I would say it fails - 3 stars at most. As a thriller with an unusual setting and a very strong female protagonist, it succeeds - 4 or 5 stars.
So 4 stars.
And I shall definitely read the sequel, The Raven.
