Yesterday I found an e-reader app on my Android smartphone I didn’t remember downloading: Play Book (https://play.google.com/books). It must be an app updated with other Google apps. I found that I could download some free e-books in English (mostly Harlequin romance novels) and also… Korean e-books. Isn’t it great? And they’re not that expensive. How to find Korean e-books? Just search for a term in hangul like 사랑 or 글쓰기 or 문고 etc. (There are also some books in Japanese and Chinese.)
You don’t have to buy, just browsing sample pages is fun. Go check for yourself!
