The Mezzanine

Ooh! I can answer this one. I'm kinda obsessed by comics at the moment. I haven't read much Marvel stuff but I'd recommend Young Avengers (a bunch of teenagers who set themselves up as sucessors to the Avengers). I slightly prefer them to the early Runaways issues. Sadly I started with Joss's run and it put me off.

On the DC side I'd suggest Blue Beetle. Jaime is a Mexican-American teenager who picks up a scarab one day and discovers that it is actually a piece of alien technology, which fuses to his spine and gives him superpowers, which he uses to fight crime. He's unusual among comics heroes in having a very supportive family and friends who know his secret identity.

I'm a massive fan of Batman stuff but I'm not entirely sure where to start reccing, there is way too much awesome!
