@Akaluv89 is correct. The locked Premium novels (and comics) have been around for a little over a year, but this Novel Platform announcement was for open publishing of free novels through our online editor.
The community is doing a fantastic job growing out the free novel database, so there is plenty to read there A good place to start is also the "New & Noteworthy Novels" collection on the front page, which is made up of free, unlocked books.
We are very close to having coins and unlocking on the web, so stay tuned!
