Trail of the Lost

It turns out you can write a book without an ending. The reader experiences a tiny fraction of the weight of the unknown that families of missing hikers face, which is made both understandable and agonizing in this book. Lankford pulls in other (solved) search & rescue stories to try to make up for the three main unsolved cases, and is well placed to inform us of the various agencies, politics, and personalities at play in wilderness missing persons cases and SAR missions.
