Looking for men

So this made me smile. It's a spoof photo spread  of male YA writers.

What  I also came away thinking was that in spite of having read almost exclusively YA for quite some time now,  I didn't know any of these chaps' work. At all.
So I took a good hard look at my YA shelves (yes, that's them over there. Can you spot the Dark Side?) It is very clearly a female dominant bookcase, but then in my defense so is the category. Looking at this season's TBR pile, of the 14 books I had in there, including the e-books, 11 were YA. Of those 11 only 2 were by men.

 I feel I have been remiss and should attempt to address this imbalance in my next couple of piles.
 I've already read books by David Levithan, John Green, Keith Gray, Patrick Ness, Kevin Brooks, Jon Marsden, William Nicholson, David Belbin and Charles de Lint, but that is about it.
 So is there anyone out there, who would like to recommend some more to me? I'm specifically leaning more to the YA Contemporary at the moment.

Obviously I will be looking a little harder at these photo spread guys too. I mean their books of course...
