The Unnamed by Joshua Ferris

This is the second novel from the writer and is not quite as quirky as the first but is an excellent read. Imagine having a physiological/psychological disease that no one else has, no doctor can help and your family can only support you as best you can. This story is about a man who has such a disease and it takes him on "walks" at any given moment. Sounds kind of weird but is really fascinating. Good book!
