A Masterpiece in Blood by Megan Scott

Perfect for fans of A Discovery of Witches and Serpent & Dove, this sequel to the sizzling dark romantasy The Temptation of Magic follows fated mates Nicole and Kyan as they attempt to root out the secrets at the heart of a shadowy supernatural organization.
Nicole and Kyan are playing a dangerous game.
Nicole is on the run, hiding from The Wake as she attempts to track down her mother’s last artistic clue and the truth of her death.
Kyan is pretending to still be The Wake’s loyal Empyreal assassin, even though his feelings for Nicole—and the mate bond that ties them together—have changed everything.
Separated, yet determined to be together, Nicole and Kyan must embark on a quest that will take them from the most powerful Vampire in England, to ancient Celtic treasures, and lost Druid sites.
Meanwhile, the Wake sees all, and the Wild Hunt is stirring.
As Nicole and Kyan get close to the dark secrets at the root of the organization, they court complete destruction—of themselves, each other, and all they hold dear.
