The Long Con (http://lookingglass.thelightgetsin.com/thelongcon.html) by E. E. Beck
Miles/Gregor
A Deeper Season (http://lookingglass.thelightgetsin.com/ads01.html) by E. E. Beck and Sahiya (novel-length, plotty, amazing and generally considered a fandom classic. It has a sequel, but some people don't like it as much.)
I thoroughly recommend all of these.
