Queen of Hearts (The Risen King, Book 2)

Aiofe and Arthur have found themselves together in the land of Faery, surrounded by heartache and hope. They're prepared to take on the worst: A war is looming on the horizon, ready to pit the citizens of Faery against each other in a battle to end all battles. Arthur was raised from the dead to stop that war, to protect the four realms from utter devastation, but when a long lost love arrives, he will be forced to question everything he thought he knew, and Aiofe will question him.
