It would be nice, though, if the book reached a conclusion.
Lisbeth Salander is a protagonist.
In a novel the hero or heroine is a larger-than-life character who takes action and moves the plot along. A protagonist is the central person about whom the plot revolves. In Hornet's Nest, Salander is the central character about whom the entire plot revolves.

Sure, it save 30 minutes on a 200+ km journey from Perth to Bunbury. So what? It's boring!
It's a highway. Easy driving, good for sleeping. Right through the heart of very boring country.
I wonder, Is the country on either side really so boring? It's hard to tell... It's a wide highway, high speed limit... Mostly road as far as the driver cares to look, when travelling at speed.
Perhaps Forrest Highway is not really a boring highway. Driving along it is certainly boring. I prefer to join the highway later rather than sooner, to enjoy the older and more scenic alternative.
Still, there's over 100km that I travel along Forrest. So I stop for a break at the one rest stop with a toilet. 
And what a toilet!
This is book three of a series. The series is a part of the continuing saga of Wish Song, Elf Stones, druids, demons and... well... an entire world of magic. The full series, in fact, starts from present-day Earth and links into a future, post-apocalyptic world of fantasy. (See The Gypsy Morph for a bit more detail.)
Who would have thought there could be so many angles on the game of golf? Who would have thought there is any humour at all, in the game of golf!
