I recently finished The Exquisite, by Laird Hunt, Author of The Impossibly (who's also the author of the unreleased 'Dear Laird Hunt, Author of The Impossibly').
It's similar in some ways to 'The Impossibly', one of the oddest books I've ever read (and one of my favorite books), but a bit more accessible (more than 2 characters in this book have actual names). There's some ambiguity as to what is really happening or happened, and like The Impossibly it's often pretty funny.
Right now I'm reading 'How To Survive in a Science Fictional Universe', about a time-machine repairman searching for his father in an incomplete universe (late in the project they ran out of money).
