Missing You By: Harlan Coben

As with all of Coben's novels, this one is full of twists and turns.  They come at you so fast, you're likely to get whiplash!  What starts as a simple exploration of on-line dating, leads Kat on several chases that all culminate in a blazing inferno of facts about her own past, and possibly her future.  Exceptionally written, ingenious plotting and likeable characters combine to to make this one of Coben's best!
