Hey, I just found this. Haven't read it yet, though, but its a zombie novel that you can read online.
Here's a plot introduction i found:
Monster Island takes place in Manhattan one month after New York City has been completely overrun by the undead.
A former UN employee named Dekalb, whose daughter is being held by a warlady in Somalia, enters the zombie-infested island with a band of East African child soldiers in order to retrieve precious AIDS medication. After surviving numerous zombie attacks, the group encounters Gary Fleck, an undead medical student who has managed to retain a high level of consciousness and self control unlike other zombies.
The novel is notable for its fast-paced, cliffhanging chapters, which were originally written as blog posts, and its unusual take on the zombie apocalypse genre.
Sounds pretty interesting, right? Here's the link to the first chapter. You should be able to work your way around the novel from there. I'm gonna start reading it.
