I'LL WALK ALONE by Mary Higgins Clark

Alexandra "Zan" Moreland is a rising star in interior design in New York City.  But she has a tragic past--her young son was kidnapped in broad daylight when he was with a babysitter in Central Park three years ago.  On the anniversary of his kidnapping, pictures surface that seem to show that Zan kidnapped him herself.  Add to this the fact that someone has stolen her identity, running up charges on her credit cards, and she soon realizes that someone is out to destroy her life.  But does this mean her son could still be alive?

I would categorize this as "junk food" or "a guilty pleasure".  Not much substance, one dimensional characters, unrealistic plot line.  But still kind of fun.
