Tarso Helge earns himself the promotion of a lifetime after killing a demon while on military protection detail. Conscripted into one of the world's most exclusive hidden magic agencies, he's sent on a mission he can't complete. The mysterious demoness Lilith is robbing museums all over the world, and what's worse, every time they meet, she gains the upper hand.


A witch who summons a demon for noble reasons and his employer's orders to eliminate her makes him question everything he knows. His life is turned on its head as black becomes white and his life begins to look like nothing but shades of grey.


The next time the pair meet, they greet one another with new eyes. Now the demon hunter becomes the hunted as Lilith looks to Tarso for her lust's next meal. Everything stands in their way, including hellish politics and the other men on his team. If they want to stay alive, they'll have to work together. The powers that be have their own plans, and Tarso and Lily are only pawns in a much larger game of chess.
