I read The Great Gatsby for the first time when I was very young and didn't remember the detailed descriptions of the lives of the rich, or even the references to white supremacy. As I started to get annoyed (because I have to reread the book), I decided to read another book alternately, one that I read when I was a child, which I also don't remember very well, but which left me with an impression of healthy kindness and camaraderie - #SwallowsandAmazons by #ArthurRansome.
I downloaded the book for free from Anna's Archive and was amazed at the quantity and variety of books Ransome wrote.
Note: Apparently, the book has only entered the public domain in the US, but in the UK (and other European countries) it is still under copyright.
