The Four Houses of Magic are poised at the brink of war. Sickness brews beneath the streets of New Orleans, and ancient enemies claw their way to the surface. And former allies are forced to fight for their future from opposite sides.

Blood witch Rose LeFey is playing a deadly game beneath New Orleans.

Separated from her werewolf mate and trapped within her enemy's walls, she's pretending to switch sides while feeding vital information to her allies above. But how can she prove her loyalty to her enemy's cause without actually serving it?

The need to reach his beloved mate is tearing Dar apart. Yet he has to lead the fight above ground—more, he has to build an army he can trust. No simple feat, as his enemies are corrupting the local werewolves and vampires. Even the dedicated witches that policed the borders between magical Houses have been compromised.

Dar, the vampire Sebastian, and the royal fae Raina desperately seek truth within centuries of lies—while their enemies plan their next strike.

Holy hex. Without help, they'll be swallowed by the dark.

To gain the information her mate and friends need, Rose has to unleash the full might of her blood magic. But will that save what she loves—or will it drive her further into darkness?
