The Pilot's Wife by Anita Shreve took me all of 24 hours to read.

The story centers around Kathryn Lyon's grief at being told that the commercial airliner her husband Jack was piloting has gone down off the coast of Ireland.  The ensuing drama follows Kathryn's discovery of Jack's secret life....one of bigamy and terrorism.

This book is predictable.  As soon as I had read the first chapter I knew where it was going.  Even the characters were predictable...you had the grieving wife, the distraught teenage daughter, the handsome yet aloof man to provide a love interest for the newly widowed main character.  The only twist in the plot was that gave me any semblance of surprise came close to the end, but I even then I should have seen it coming...given the location of the accident and the current political climate in said location.

If you have a day to spare and you want a book that doesn't require too much concentration, provides you with the requisite girly romance aspect and the accompanying fluff, then 'The Pilots Wife' is exactly what you need.  If you're looking for something meaty, something that you can really get involved in....then I'd suggest you pass this one by.
