Another non-troublesome book that I super loved was The Guernsey Literary and Potato Peel Pie Society. It is a gem. The title veers toward cutesy, and the whole thing ends up being a warm fuzzy but who cares? The characters are good, the setting is great, and you get to learn about WWII and how the Germans took over Guernsey (an island between England and France). Loved it.
Grab either book, a cup of tea and have yourself a great afternoon.
