Black Blossom — M.C.A. Hogarth

The high priest of Shame in Kherishdar is shattering--
--and the only thing between him and his ruin is the gentle Calligrapher, Farren Nai'Sheviet-osulkedi. When they are dispatched by the god of Civilization to Qenain, the House of Flowers, they find it in disorder, having fallen prey to a mysterious influence... an alien influence... a "human" one. Can one man heal Shame in time to save him and Qenain both? Or will they both fail? And what will happen in--and to--the House of Flowers?
A genteel, conversational fantasy of society, culture... and the perversions that threaten them.
