The good thing about this show is that, unlike Lost, it actually answers the larger questions. As those questions are answered, another plot will develop. Lost spends too much time with its audience going, "what? huh?" which is exactly why I quit watching. It drove me crazy and then I got to the point where I just didn't care. But, Heroes is definitely NOT like that.
There is a graphic novel online?

OMG, I know what I will be doing tonight!
