The Millennium Trilogy is a series of three bestselling novels written in Swedish originally by the late Stieg Larsson. The novels in the series, The Girl with the Dragon Tattoo, The Girl Who Played with Fire and The Girl Who Kicked the Hornets' Nest, were first published in 2005, 2006 and 2007 respectively.
Larsson, who was disgusted by sexual violence, witnessed the gang rape of a young girl when he was 15. The author never forgave himself for failing to help the girl, whose name was Lisbeth – like the young heroine of his books, herself a rape victim, which inspired the theme of sexual violence against women in his books.
The primary characters in the series are Lisbeth Salander and Mikael Blomkvist. Lisbeth is an intelligent, eccentric woman in her twenties with eidetic memory whose social skills are rather poor. Blomkvist is an investigative journalist, a celebrity in his own right, and has a history not totally dissimilar to Larsson's.
Larsson wrote about three-quarters of a fourth novel before his sudden death in November 2004. His partner, Eva Gabrielsson, possesses the notebook computer with the manuscript. Outlines or manuscripts for one or two more books may exist.
