I don't really read manga. I don't know why, I'm just more into traditional books. I've read maybe... six manga books in my life and only own one. But a friend let me borrow three in a set of this one called "Uzumaki". It's about this town with a strange, evil-like connection to the spiral shape. People become obsessed with it, the ashes from the crematorium rise in a spiral formation, and just flat out crazy s**t* starts happening. It's like Poe/Lovecraft stuff in manga form.
It might be worth a look if you're into the stuff, or even if you're not. I'm really not, but I'm enjoying it.
*Examples of such crazy s**t:
Note that it does make a
little more sence when you read it in order and in context.
