The first time I remember being drawn in by a m/m story was in Cry to Heaven by Anne Rice. I loved that coulpe, and rooted for them. But, when I fell headlong into it as definitely due to the slash fanfiction of Smallville fandom. I remember reading it and laughing, thinking, What is this absurdity? And then reading a little more. And a little more. And then just voraciously gobbling up all the fic in that fandom good, bad, I didn't care. And from there I started seeking out original novels and fiction focused on m/m relationships.
