At the beginning of The Walk by Richard Paul Evans, Alan Christofferson's life is as near perfect as a human's can be. His wife McKale is the center of his life and his business is prospering.
When McKale has a disabling accident, Alan devotes himself singlemindedly to her care. Even though this is a proper prority, is turns out to be a disasterous mistake. Alan's business partner destroys Alan's business. When McKale dies, Alan believes he has nothing left to live for, but with almost her dying breath, McKale makes Alan promise to live.
Alan decides to walk across America from Seattle to Key West. What begins as an escape gradually turns into a journey of discovery. The road is neither smooth nor easy, but Alan persists.
Even without high suspense in the plot, I find myself looking forward to the next part of the journey.
