Vampire Undefeated (Keepers of the Chalice #4)

To cure or not to cure, that is the question.

Maddy and Caleb have fallen for the enemy—each other. But their opposing allegiances are determined to tear them apart.

Caleb is the vampire king. He knows strengthening vampires will ensure they can fight for their survival. Except it may also make them invincible… Maddy is a hunter. Creating a cure will protect humans from violent, blood-thirsty vampires seeking to dominate the world. She just needs to stop the Order from using it to exterminate vampires altogether.

There is no right or wrong. Enemies are everywhere. And if they lose, humanity will pay the price. Maddy and Caleb are about to find out—is their love an abomination? Or are they the key to unite them all?
