Worm is an online series about a 15 year old girl - Taylor Hebert - who has just acquired super powers. She lives in an Earth where humans have had powers for about 30 years. The get them through traumatic experiences, called trigger events. The event shapes the power. Taylors power is the ability to sense and control bugs. She aspires to be a hero, but on her first night out in costume, her goal may be side tracked.
It is a superbly written story and does a great job at realistically portraying human nature. It stands at the top of the super hero genre for me. One of the things I like is how the smart people are actually smart, and pretty much always are able to overcome the "tanks". Taylor's power sounds weak, but through smarts and creativity she becomes one of the most versatile and powerful capes in the world.
The story is broken up by story arcs. Each arc is about as long as a short novel. There are 30 arcs and one epilogue. It is a monumental feat of writing.
I highly recommend this to anyone, not just fans of comic book heroes. Try the first arc and you'll be hooked.
