Lawyer and amateur sleuth Thora Gudmundsdottir is brought in by a local bank to handle legal ramifications of an unusual situation. Icelandic contractor Berg Technology is doing preliminary studies and constructing infrastructure facilities for Arctic Mining for a mining operation in the wilderness of eastern Greenland. People have been there for nearly a year, but something has happened to unsettle the workers. In fact, most of them refused to return after coming home on leave. Two people remained on site, but haven't been heard from in over 10 days. Now, all communication has been lost with the remote site.

Thora is part of a team sent to the remote site by the bank to investigate the problems. When it's learned that several workers disappeared from the facility earlier, speculation runs rampant among the team members. Did they get lost in the snow, or were they killed? The explanation is difficult to believe, but answers many questions when the extraordinary facts are finally uncovered.

Nordic names make for deeper concentration to keep characters and locations straight during plot development of THE DAY IS DARK, but that should not stop you from reading this excellent, impressive suspense novel by Yrsa Sigurdardottir. If you are looking for something out of the ordinary and unique, THE DAY IS DARK will surely satisfy.
