The final battle is no longer a whisper on the horizon—it's here. And not everyone will survive it.
As ancient realms fall and hell itself surges upward, the lines between light and shadow blur. Jack, a demon with Mammon blood and a defiant heart, has been to the brink of ruin and returned—only to find purpose in the one place he never thought possible: the fae realm.
Nymera has chosen to protect her Hollow, not to fall for the enemy. But when a bond takes root between her and Jack, neither prophecy nor prejudice can stop it from blooming. Together, they must survive the Trials, unite fractured powers, and stand at the forefront of a war that could devour the world.
Allies will fall. Enemies will rise. And the bond between a warrior and a demon may be the last hope left.
This is the war that will end the darkness—
Or drown them in it.
