Before the Fall by Noah Hawley

So I was reading this book and then it like just ended.  And it kind of makes sense to end it there, but it is so abrupt.  I did enjoy the book.  It is the story of a plane crash that had only two survivors, a middle aged man who was on a swim team in his youth, who managed to swim for miles to shore after the crash, saving a four year old boy who had also been on the plane.  The book tells the back stories of the passengers and crew of the flight as well as the story of the survivors in the aftermath.  It is well-written and compelling.  I received this book free to review from Netgalley and I did enjoy it.
