Dúnmharú: The Favor

Cahal Kearney, the Dúnmharú, asked a favor from the Maerrighan to save his friend, Maggie, and his dog, Daegen.  She now calls payment due.

His Fae father, a man he does not know, is captive on the world of the UnSeelie, held by the Black Queen. Surrounded by the darkest creatures of Pandaemonium. 

To repay his debt: rescue Sionnach, or die in the attempt.

Annabeth Hughes, his girlfriend and vampire, has been asked a favor by Bishop, her sire. Travel from London to Atlanta and quell a vampire uprising.

She arrives in the middle of a hostage crisis. Rogue vampires threaten to slaughter innocent humans and stream the carnage across the internet.

Her favor becomes a race to rescue the hostages.

Fail and vampire-human relations go to hell.
