Prague, 1970
Great powers eye each other across the Iron Curtain. Secret warriors wage secret wars--some with guns, some with words, and some with magic.
CIA officer Gabe Pritchard has a mission: to transport a critical defector back to the US. But Gabe also has a secret. On a job in Egypt he stumbled into what he thought was a Soviet cell meeting--but Soviet cells don't have altars or sacrificial knives. Now Gabe has splitting headaches, like there's something burrowing inside his skull, and finding help means joining a different, and much colder, war.
Tanya Morozova works for the other shop in town--at least, when her KGB bosses are watching. But the young intelligence officer has a second secret life as an agent of the Ice, an ancient order of sorcerers fighting for control of elemental Hosts who have the power to change the world--or destroy it. As Tanya's enemies catch a critical Host in their web, she's running out of options. Gabe Pritchard may be her only chance--or the bait of one last deadly trap.
