Somehow I got sucked into the chilling, vibrant, complex, horrifying, addictive world of Swedish, Norwegian and Icelandic crime novels. Expect deep psychological insight, a riveting plot, lots of passion, grand guignol scenes of horrific abuse, and a complicated, flawed, yet deeply human detective floundering through it all. Some authors to note are Lars Kepler (Sweden, featuring Finnish detective Joona Linna), Jo Nesbo (Norway, featuring alcoholic detective Harry Hole), Camilla Lackberg (a small Swedish village featuring crime-solving duo Ericka Falk and Patrik Hedstrom), Yrsa Sigurdardottir (Icelandic sleuth Thora Gudmondsdottir), and Mons Kallentoft (Swedish mother and detective Malin Fors). Expect to get hooked.
