After reading Sarah Weinman's review of Thomas Pynchon's INHERENT VICE, I'm going to have to pick up a copy and see for myself. He lightens up with this one, Weinman speculates that could have read Hard Case Crime novels as research, and the book trailer definitely intrigued me.
Also new to the shelves is VANISHED by Joe Finder. This is the first in the Nick Heller series, a high powered investigator with Special Forces training. All of Finder's novels are gripping page-turners, so VANISHED is a perfect weekend read.
If you want something light and fun, I recently read Sherrill Bodine's TALK OF THE TOWN. The novel features gossip columnist Rebecca Covington, a fabulous fashionista who knows everyone worth knowing in Chicago. The tone is light, fun, over the top, and Chicagoans should get an extra kick out of it.
