What sorts of things do you like to read? Are you looking for fiction, nonfiction, any particular genre? Just any good book?
I recently finished Dan Simmons' Black Hills, and enjoyed it quite a lot, although I think The Terror is superior. But anything by Simmons is worth reading.
Sara Gruen's Water for Elephants impressed the hell out of me; I wasn't expecting the story to go where it did.
Ken Bruen's Once Were Cops is the most cinematic novel I've read in years - quite the thrill ride, although you have to be aware there are NO sympathetic characters in the story.
Arturo Perez-Reverte's Alatriste books are wonderful, and his contemporary fiction (Queen of the South and The Painter of Battles especially) is even better.
I love pretty much everything of Michael Connelly, Lee Child, Dennis Lehane, and George Pelecanos that I've read.
