The Mountain Between Us by Charles Martin
I checked this out from the library. I had to recheck it before I even started reading it as I've been pretty busy with the quilt retreat prep, attendance, and recovery. :) I have started reading it now, but haven't gotten far into it yet.
This has recently been made into a movie which will be released in October of this year. It fulfills the "A Book That's Becoming A Movie in 2017" category of the 2017 Reading Challenge.
