Last year we started the Christmas tradition of Jólabókaflóð (originating in Iceland). Where you open a book gift on Christmas Eve and spend the evening reading together. I am finding it almost impossible to choose a book for my dad as he is not a huge reader (of books, he reads lots of articles).
Last Christmas I got him "How Do You Live?" by Genzaburo Yoshiro and he seemed to really enjoy it and even went on to recommend it to my sister.
This year I am absolutely stumped. He has read biographies of Washington, Lincoln and Adams that he has enjoyed. He also read and liked the Lord of the Rings trilogy at one point. That's about all I have got to go on 😅
For context he is in his 60s and is a retired attorney. He currently volunteers as an organizer/facilitator on global humanitarian projects.
Editing to Update: Wow, there are so many good suggestions here, many more than I thought I would get with the little I had to go on! And some of them sound spot on to the type of thing he would enjoy. I have a long list now that should sustain my book gifting for years to come! Thank you so So much!
