Gimmie your recomendations-new meaningful reading material?

My friend recently introduced me to Zen by Brad Warner and I love Warner's cut the bullshit and melt the sugar coating writing style. I'm not big on religion and I consider myself to be Agnostic for the most part but I like his insight. I'm 17 and I'm looking for something insightful, something that has meaning. I don't mind the occasional teen cookie cutter romance (Like Twilight lol) but I want something more deeper, and insightful. I like reading so any genre is a-ok. So throw them at me :)
