Watcher Compelled - Watchers of the Gray, #6

In the shadowed streets of Toronto, there exists a garrison of soldiers like no other-nine immortal warriors, half-Archangel/half-human, living unknown amongst the city, defending humanity from the Daemons of the Hell realm. After millennia of death and violence, Lady Divinity has granted them reward for their servitude, a gift that makes her mighty warriors stronger than ever--Love. Before his transition, Bo, the immortal Viking, had love taken from him.
Now, over eight hundred years later, he has a second chance. The only problem? He's falling for the enemy.
