I received a free copy of this book in exchange for an honest review. This detective thriller takes place in Iceland and involves investigations by Ari Thor, the main detective, and Isrun, a Reykjavik journalist into a cold case from 50 years earlier as well as more recent up-to-date cases both locally in northern Iceland and in the capital. There's sub-plots to intrigue the reader as we discover more about the main characters. The whole thing is engaging and well-written as the characters are developed and fleshed out. I enjoyed this and ploughed through it quite quickly which is always a good sign. It's the second of these novels by Jonasson that i've read and I preferred it to Blackout.
