Hey! I recently started reading a web serial called Worm, and it's completely amazing! Worm is the story of a young girl named Taylor who lives in a world of super heroes and super villians, collectively known as "Capes". She secretly has the ability to control bugs, and hopes to soon use those abilities to join up with the super heroes. This story is currently over 1,000,000 words in length and entirely posted online. The author, Wildbow, updates often and the only income they're getting from all this is through donations. Wildbow deserves some more attention because this story is one of the best I've ever read. It contains some of the most interesting and unique powers I've ever heard of. You won't find any superman type power sets here (minus one or two, but each with their own twists). It's got great characters and nice character development. The story flows well; in the entire time I've been reading it I haven't been bored once.
Worm is the type of thing that, at the moment, can only be learned about via word of mouth. It's not really advertised anywhere, and that's a shame. Wildbow deserves to get some more fans. Do Wildbow, and yourselves, a favor. Check it out. I'm crappy at explaining stories so check out the "about me" page linked below. Give it a shot. You won't regret it.
