I've got to the point that I only read mm books now. I just can't get enough of them
who's everyone's favorite books/authors because I'm trying to find some new authors that I haven't enjoyed as of yet. Much love and respect to all those members that share so many amazing books for us! 
I was a huge science fiction fan until I discovered MM a few years ago and I now find I read very little else.
My first book was by Amy Lane (Clear Water) and I really loved the Johnnies series.
Then there is T.T. Kove, Jeff Erno, Kate Sherwood, Sean Michael, Carol Lynne, Andrew Grey, AKM Miles, Diana DeRicci, Kaje Harper, N.R. Walker, Cristiane france, R.J. Scott...
The list just goes on an on.
I really like the stuff published by the Goodreads MM group as it has some really good stories by lots of different authors.
