Ugh, this book was so good! I was a little bit slow to get going but once it clicked I couldn't leave it alone. It's such an interesting and heartbreakingly sad story. My heart ached for Agnes, particularly towards the end.  
The family dynamics at Kornsá were fascinating as were the flashbacks from Agnes's past. I thought the writing was so atmospheric I was transported to Iceland every time I opened this book. I'm going for real later this year and now I'm even more excited to see it in person.
