Earlier today, publishing giant Alfred A. Knopf revealed the title and release date for the the fourth installment of Stieg Larsson’s hugely popular Millennium series. Larsson launched the franchise with The Girl with the Dragon Tattoo in 2005; more than 80 million books have since been sold worldwide. The Girl in the Spider’s Web will arrive in stores on September 1 and will be the first book in the series not written by Larsson, who died of a heart attack in 2004.

Written by Swedish author David Lagercrantz, Spider’s Web will not include the partial manuscript for a new book that Larsson's girlfriend, Eva Gabrielsson, found on his computer after his death. Gabrielsson has been critical of Lagercrantz, calling the author a "completely idiotic choice" to continue the beloved series.

The book's plot is being kept under wraps by its publishers, but the story will focus on the established leads, Lisbeth Salander and Mikael Blomkvist. Watch the book trailer below.

There have been three Swedish films based on each installment of the trilogy. American director David Fincher (Fight Club, Gone Girl) helmed a new version of The Girl with the Dragon Tattoo in 2011. Starring Daniel Craig and Rooney Mara, the movie brought in over $230 million for MGM.
