The Passenger by Lisa Lutz, 294 pages

The book begins with Tanya Dubois on the run because her husband has just died and she can't afford to be around if any difficult questions are asked. 

Through this fast paced story, the true story of Tanya Dubois is revealed, along with the reasons why she ran (it turns out) for the second time.

This is one of the fast, suspenseful books best read in one quick sitting so you don't think too much about the story.  It was a fun, suspenseful romp, with plenty of twists and turns.
