I finished Await Your Reply by Dan Chaon, and it was great. It's thrilling, fast-paced, and filled with real, true-seeming characters. It deals with fascinating questions of identity, history, and reinvention, along with affairs in the Arctic, a dried up lake, magicians, and international thievery. I only wish it could've been a little bit longer.
