Await Your Reply by Dan Chaon

This was a pretty unusual story.  It follows three different sets of characters, and it's a long time before you learn how they are related, but you eventually do.  Miles Cheshire is searching for his twin brother, Hayden, who has been missing for 10 years.  Lucy Lattimore has run away from Pompey, Ohio, with her former high school history teacher, George Orson, a few days after graduation.  And Ryan Schuyler has learned that his parents aren't who he thinks they are, so he walks away from his college campus to remake himself. It is very well written and I often couldn't put it down. I rate it 4 out of 5.
