Fantastic writer.  I've only read Equilibrium, but each chapter leaves me wanting more.

I haven't read all of his work, but I can tell you that Ragnarok is amazing.  The story and the writing is spectacular.  Unfortunately, I haven't seen anything from the author in over a year, so I'm not sure if the story will ever be completed.

Twill is awesome.  Check out Uncertain Future or What Lies at the Core for longer reads, or check into his other stories for shorter, less plot driven smut.  Either way, this guy can spin you a tale.
