Just finished The Chinatown Death Cloud Peril; now I'm working on Alhazred: Author of the Necronomicon (a biography) by Donald Tyson. (Chthulhuiana..i.e. inspired by H.P. Lovecraft.)
Have to wait for Changes to come out in paperback, or A2 will kill me (she's not comfortable reading hardcovers). Did you know there's a Dresden Files role-playing game out?
