Yuletide 2014 recs, part 2

I haven't read half the Yuletide fandoms half as completely as I would like (I've still got some queued up), but here are some more I did get to and loved. (Rec post 1, including my awesome gifts, is here.)

( Recs in Oryx and Crake, Picture of Dorian Gray, Riddle-Master trilogy, Star Trek - Rihannsu, Tam Lin )
