I'm reading two things, the first Harry Potter and the Method of Rationality. It's a fan fiction were Harry is extremely smart/borderline evil, kind of like Yagami Light, and is trying to merge science and magic and possibly take over the world.

The second is called Worm and is set in a world with super heroes in it. It's kind of like a Marvel or DC universe except far darker and more realistic as people sometimes die in very gruesome ways. Which is to be expected when psychopaths are running around with super powers. Also, all the powers are surprisingly unique.
