Our war will not unfold in your imaginary heaven. We will fight on Earth with human beings as pawns and weapons.

Lu Darlington is a seer, bound to the daemon Talion through ritual and blood. It’s not a role she enjoys, but she has little choice: daemons take what they want and destroy whoever stands in their way.

So Lu’s surprised when Talion doesn’t punish her for her newfound ability to keep him from possessing her whenever he likes. In fact he’s pleased. The stronger she is, he explains, the more powerful he becomes.

And he needs that power, because a war is brewing in the daemon world, a war that will be fought by—and through—humans.

Lu’s friend Lisa Duncan can’t see daemons but she’s seen what they can do and so has stayed far away from Lu for years. But after a bizarre attack on Lisa leaves half a man dead and she learns it’s only the first skirmish in the daemon war, Lisa realizes the safest place to be is with Lu.

Then Talion sends Lu away to teach her skills to another seer and Lisa must stay behind to look after Lu’s son Solly, conceived through a daemon ceremony with Talion. At four years old Solly’s seer abilities are already so strong Lisa is sometimes more afraid of Solly than for him.

As Talion’s enemies grow bolder, Lisa and Lu face attacks from every direction. There seems little hope any of them will survive—until Talion and his allies devise a plan.

The only problem is how much it will cost.
