Robert Galbraith's Career of Evil
The third book in JK Rowling's pseudonymous series falls into the grim/gritty/grisly side of things even more so than the earlier ones, as a serial killer is obsessed with Cormoran and Robin and is stalking them with some pretty awful things in mind. Besides the serial killing, there are also mentions of rape, pedophilia, and other gross stuff, so be forewarned. As always, the pacing here is great--I read the whole thing pretty much in one sitting and could barely put it down for bathroom breaks. I still HATE Robin's fiance in a big way, which does inform some of my feelings on this book, but Robin is great, Cormoran is great, all of the suspects are viable and suitably creepy, etc. Solid stuff. A-.
