Part of the Ancient Blood series.

Dulcie Evans knows from the start that she and Dr. Matthew Winter are a perfect match, yet how can she convince a man who's virginal in the ways of vampiric love? Matthew has always striven to disguise his animal side since he fears the consequences of releasing the vampire in him - until he meets Dulcie. She's the woman of his dreams and the missing part of his soul. Unfortunately she possesses a major drawback in the form of an ex-lover who will stop at nothing to see Dulcie back in his arms and Matthew dead.

Review quotes for The Blood Doctor by Kate Hill

HOT! HOT! HOT! Did I mention HOT?
~Dawn Mercier, Romance Junkies

The story is not sacrificed in order to include more sex; instead the sex augments and is necessary to the story. This is a delicate balance that must be maintained by any author of Romantica and Ms. Hill has accomplished it.
~Nicole La Folle, Timeless Tales

In a short number of pages this story has it all; sex, passion, love, sex, jealousy, suspense, sex, action, a battle for the lady, and, of course, more sex.
