For example, I just bought Peter F. Hamilton's book The Reality Dysfunction, 1200+ pages, on Kindle for $10 USD.
His work is professionally written and edited, the English is excellent, and the story isn't biased by ultra-nationalism or racism. Female characters don't exist just as a backdrop for male characters.
This author alone has a bibliography of over 20 full length novels, of 700 to 1200 pages each.
On webnovel.com, $10 USD would have bought me 500 stones, or 40-45 chapters. I've tried to emphasize the importance of quality in story structure and translation, but the quality on webnovel.com is nowhere comparable to, say, this author's works.
