There are a few authors here that I follow somewhat slavishly, because they're really, really good. Mihangel is one of them.
When I stumbled onto online gay fiction, way back when, one of the first stories I read was 'A Scholar's Tale.' It was excellent then, and just after its 18th birthday, remains so. Being a ex public school boy myself, I tracked down 'Yarborough,' which was fun - you should try it. The clues are there.
Amser is another wonderful novel.
Must stop waffling. You lot should now toodle off and read some Mihangel: https://awesomedude.com/mihangel/index.htm
