One of the best books I've read this year. The story is thrilling and even though you constantly get new information, you're just as in the dark as the characters themselves. The writing style is great, but the thing I enjoyed most was how brilliantly Sigurdardottir is at giving you goosebumps with the tiniest of details. The warning on the cover to not read it alone in the dark is there for a reason! I felt just like Katrin and Lif: I wanted to look away and not know what would happen next, but not knowing was even worse, so you couldn't help it and had to look anyway. It was fascinating to see how these two storylines came together. And the ending leaves you with goosebumps again, in the best of ways. I can absolutely recommend this!
