<p>Rattlefin is a home for original web serials: stories released chapter by chapter, free to read, no account needed. Every story has world pages for its characters, places and lore, and they only show what you've reached, so nothing is spoiled. Writers get a Studio to write, schedule and publish, with maps whose pins appear as readers get there and recaps they approve. Start with The World Is Lying, a horror mystery about a coal mine where the dead are still working.</p>
