Darkkin Queen is the 16th science fiction book in The Demon Accords series by author John Conroe.
Tatiana Demidova – natural-born vampire, Coven royalty, martial artist, CEO, partner of the Magic Hammer, mother of the Fallen Angel. She balances diverse quests, except for most who don’t face demons from Hell, monsters from Elves, alien invaders, or resentful world leaders. Her life is hectic as she works to save her children, her spouse, her friends, the stockholders, and the world itself, in that order.

There are more problems with attacks from Faerie, there is an ancient vampire, and public opinion about our heroes continues to be empty.
