I liked it. However, generally speaking, I like the vast majority of books that are set in Iceland as I am an Icelandophile.
It is quite typical for both a Icelandic ghost story and an Icelandic mystery. There are two stories being told at once, the story about a psychiatrist and the other about some people renovating a house in an remote village and the two stories have alternating chapters.
The book is set in the region around Ísafjörður (NW Iceland) which is a nice change from books set in Reykjavik. However Yrsa does tend to set her books all over Iceland (and one was set in Greenland).
I would rate is 4/5.
