What is the name of Stieg Larsson’s third book?

For a long time I have been certain that the third book in the Millennium-trilogy by Stieg Larsson would be named Castles in the Sky. That is that name many people use, and which is used at stieglarsson.com.

However, now I am not so sure. Just today I came across translator Steven T. Murray’s page on Wikipedia, and there I found that he was currently engaged in translating the third book of the Millennium-series, entiteled The Girl Who Kicked the Hornets’ Nest.

This title makes some sense – The Girl With the Dragon Tattoo, The Girl Who Played With Fire, The Girl Who Kicked the Hornet’s Nest – all titles with “The Girl Who”, so that it becomes a series by virtue of the naming. Also, Castles in the Sky makes sense from the point of view of the content of the book, but since the book is to a large extent about Lisbeth Salander, so does “The Girl Who Kicke the Hornets Nest“.

Oh well. I guess we will soon know which it is!
