The Unamed - Joshua Ferris

At the start, Tim is a lawyer in New York with the usual trappings - a pretty but bored wife, an alienated daughter, a too big house - and the unusual problem of losing control over his body and compelled to walk until he collapses.  No cause or name can be found for this condition, and similar to mental illness or addiction, the unamed warps his life. Plot lines are raised and dropped and the story, somewhat disappointingly, goes in a straight line from start to finish. Any expectations of salvation or redemption are dashed halfway through, and unlike Then We Came To The End, the ending fails to offer any satisfaction or any relief.
