Bryan, Kathleen -- The Serpent and the Rose
Copyright page tells me this is Judith Tarr, whom I used to enjoy.
This one is enjoyable too. A Europe-analogue (in which the
Christianity-analogue is magic-positive, for once) is threatened
by a tyrant king. Various orders of mage-monks attempt to deal
with this. The language is sensuous and the medieval detail
resonates (as you'd expect from Tarr).
