I finished up Walls of the Universe
by Paul Melko. It was a thoroughly enjoyable read. I've really become quite a fan of alternate universes or worlds and time travel and reliving your life over and over.
I'm almost done with Indistinguishable From Magic
by that guy up there ^. First Trek book I've read in a while. The next thing on the list is the new Stephen King & Stewart O'Nan novella A Face in the Crowd
