The seventh novel in the successful Millennium series about the characters Lisbeth Salander and Mikael Blomkvist went on sale in Sweden on Friday.
The series was created by famous Swedish crime writer Stieg Larsson, retold by David Lagercrantz and now passed on to a new author, Karin Smirnoff.
Smirnoff, who like Lagercrantz before her is to write a total of three follow-up novels in the series, has set the action of the novel even further up north in Sweden this time.
In Swedish, the work is called Havsörnens Skrik, which translates into English as "The Cry of the Sea Eagle."
It is not yet known when the book will be on sale in the rest of Europe.
The series of novels about the hacker Salander and the journalist Blomkvist began in a trilogy by Larsson, who died in 2004.
The books were published between 2005 and 2008 and were translated to: "The Girl with the Dragon Tattoo," "The Girl Who Played with Fire," "The Girl Who Kicked the Hornet's Nest."
The new Millenium author Smirnoff made her debut in 2018 with "Jag for ner till bror" (My Brother).
She had never written crime novels before the Larsson follow-up.
"We share an interest in violence," she told the TT news agency in an interview published on Friday.
In a Facebook post by Swedish publisher Polaris, Smirnoff said Stieg Larsson had created "a fantastic universe" with the novel series, adding that it was exciting to try to create something of her own in this existing universe. - dpa
