The Girl with the Dragon Tattoo by Stieg Larsson and Reg Keeland:

A spellbinding amalgam of murder mystery, family saga, love story, and financial intrigue…. It’s about the disappearance 40 years ago of Harriet Vanger, a young scion of one of the wealthiest families in Sweden…and about her octogenarian uncle, determined to know the truth about what he believes was her murder.

It’s about Mikael Blomkvist, a crusading journalist recently at the wrong end of a libel case, hired to get to the bottom of Harriet’s disappearance…and about Lisbeth Salander, a 24-year-old, pierced and tattooed genius hacker possessed of the hard-earned wisdom of someone twice her age, who assists Blomkvist with the investigation.

This unlikely team discovers a vein of nearly unfathomable iniquity running through the Vanger family, astonishing corruption in the highest echelons of Swedish industrialism – and an unexpected connection between themselves.
