I’m personally interested in non-fiction so I have found books like Sapiens, Outliers, Elon Musk, Thinking fast and slow, among others. There’s also literature but I’m not as interested yet, although I plan on reading the alchemist because its original language is Portuguese. The “bad” thing about this page is that with the free version you have to wait 22 minutes to download between books. When I look for a book I search the author’s name, it’s easier. I have downloaded and imported 10 books into LingQ (And there are many more that interest me on the page) . I made the lessons private because I don’t know about copyright stuff. Enjoy!
