Have you tried Archive.org or https://www.gutenberg.org/? And Calibre.
If you’re on MacOS, you can use Books to convert it or Preview specifically to pdf. These are both Apple stock apps.
There are plenty of resources online on how to convert to pdf. You can also check out Kobo, Smashwords, ebooks and this old article from https://www.makeuseof.com/tag/buy-ebooks-best-ebook-stores/). Have fun.
So far, 2 users and 4 communities but I’ve only been here for 3 weeks (almost).
Some posts are so uplifting that it restores my faith in humanity, then the next post has nothing but toxic comments that makes my eyes hurt.
