Common reading suggestions?

I put this on Facebook, too, but I am now on the FYEX (first-year experience) Taskforce (sounds official, right?) and one of our jobs is to select the common reading for Shepherd.

Some guidelines: the book should appeal to lots of different groups (not just freshman, not just English-major types), should be in paperback (or at least an affordable hardcover), and should be no more than 300 pages. You can read about this year's book and the events we've held around it here.

Any suggestions, oh wonderful readers?
