FreakAngels is a graphic-novel style webcomic by Warren Ellis and Paul Duffield. The story follows 12 psychic teenagers who are trying to survive in flooded Post-Apocalyptic London. It's starting to pick up speed, and Warren Ellis is his usual charming self. The violence in the comic can be a bit graphic and it's definately not for younger readers, but it's pretty interesting stuff. Their first book is also available.
