I am reading Upstream by Eric Wade. It's a continuation of his earlier book, Cabin, which I read a couple of years ago.
For several years, Wade and his wife have traveled twice a year to his cabin on a river for an extended stay in the Alaskan wilderness. The first book was about their earlier years, the cabin they built, the wildlife, and the enjoyment they got from the solitude of their cabin, which they reached through a river trip of a few hundred miles on, I think, three different rivers.
In Upstream, they are facing the added difficulty of the trip, the stay, and the maintenance required at an older age. While they still cherish the time and love the cabin and everything they have enjoyed over the years, they are facing the challenges that come with aging, as well as weighing the likelihood that they have grown too old and may have to give it up.
The author does a great job of describing the scenes that he writes about while maintaining a narrative that can be followed.
