As you probably already know Camilla Lackberg is the most popular writer in Sweden today. She is young and beautiful, and has quickly produced a stream of crime novels all set in the region where she once lived.
You can get more information from here.
The Ice Princess is first in this series. Then comes The Preacher. Then The Stone Cutter. There are more in the series, but I have not tried them yet.
The books are set in the small holiday resort town of Fjallbacka, in northern Bohuslan. I looked it up on Google maps. Thousands of tourists visit this town in summer but for the remainder of the year there would be barely 1000 residents. The mixture of people makes the place a good site for the stories.
These books all follow a formula. Same central characters. Same region, town, general minor characters. The story is always an example of how horrible some people can be. The heroes of course solve the crime; good triumphs over evil. Then there is a little section where hidden elements are exposed to view. The reader may have worked out this dialogue or not, but it is made plain. I like this gradual conclusion with all details securely finalised for me. The characters are well drawn and usually believable, just as if you worked with people like this.
Would I recommend these novels? Yes. The Preacher was really good, I thought, and had me awake long into the night to finish it. Actually, I did not enjoy The Stone Cutter as much. One or two of the characters were outside my world completely.
