In the Service of the King is the first book in the Vampire Warrior Kings series.
Kael McQuillan is the Warrior King of the Vampires and Shayla is the human woman offering her blood. They are both strong willed and stubborn, but they quickly realize the attraction they share is more than they thought.
“You are the pulse of my heart”
I believe the books in this series were first released in 2012, however they have all just been re-released with some new material. They are very short books at only just over 100 pages each, but perfect if you’re looking for a quick read with a hot vampire and a happy ending.
