Webnovel.Forum

I just finished reading "Taylor Varga" - a huge, interesting work with a smooth plot, I advise. It is also interesting to read Coeur Al'Aran with his adventures in the world of rwby.
I can also try to advise you to pay attention to Russian authors, they sometimes have very interesting works, but their fanfictions are very rarely translated.
For example, there is a cycle of works "Неудачный выбор", but after 4 books, I stopped reading. For example try to check noslnosl (hp and other), Chernoyar (kancolle) and mb "ШПИК.".
A regular online translator is enough for comfortable reading.
If you do not know these fandoms, then it becomes even more interesting to read, each work is like a new book.
