The Millennium Trilogy, by Stieg Larsson — The whole series kind of felt like a Choose Your Own Adventure tale anyway — like Larsson would get to a certain point in the plot, and then write out a number of possible directions the plot could go. And then he’d throw a dart, and that’s the way plot went — and it was often unexpected, and against any reasonable logic. I mean, after getting shot at, Mikael should a) Retreat to Stockholm to finish his research in safety. b) Report the incident to the police and give up on the project. c) Install some security equipment at his remote cabin, continue the project, and hope no one tries to kill him anymore.
