I mentioned this one in passing, years ago: Those Who Hunt the Night is a vampire novel set in the early Edwardian era. It is… unsentimental and unromantic about vampires; they are monsters that think and eat people. And they are not what the hero of the book is fighting. And, hot damn! …Barbara Hambly wrote a couple more sequels than the one I knew about. Guess those all go on the Wish List.
Adieu, Declare, adieu.
