A new novel in late Swedish author Stieg Larsson’s Millennium trilogy will hit shelves in 35 countries this August, the book’s publisher announced Tuesday.

The unfinished manuscript left after Larsson’s death in 2004, That Which Does Not Kill, was completed by Swedish journalist and author David Lagercrantz, the Guardian reports. (While the English titles all took the The Girl Who _____ format, the original Swedish titles did not.)

The book will reunite readers with troubled computer hacker Lisbeth Salander, the titular character of The Girl With the Dragon Tattoo, though the plot has so far been kept under wraps.

The entire series has sold more than 80 million copies worldwide and seen multiple film adaptations including one starring Rooney Mara and Daniel Craig. Larrson reportedly had several more novels planned when he died.

“What I wanted to make use of in the book was the vast mythology that Stieg Larsson left behind, the world he created,” said Lagercrantz, who told newspaper Dagens Nyheter that he worked closely to recreate Larsson’s writing style.
