War is being waged against the Descendants and Saira Elian is desperate to stop the Mongers' savage bid for power...
Saira's search for kidnapped mixed-bloods draws her into the Mongers' stronghold, revealing the horrible truth behind the irresistible Monger ring and the vile plan to cleanse Family bloodlines ... permanently.
To prevent a brutal massacre, Saira and Ringo travel back to Bletchley Park during World War II where they team up with Archer from the past to crack a Nazi code and expose a Monger traitor intent on changing the course of history. They team with a female commando from the French resistance to hunt down an elite unit of Monger soldiers - Hitler's Werewolves - before the terror squad can strike a fatal blow at the heart of the Allied war effort.
Their desperate manhunt drags Saira, Archer, and Ringo into the London underground on the eve of a Nazi bombing raid where they come face-to-face with the Monger assassin on a suicide mission to split Time. With the lives of all mixed-bloods in peril, Saira must make a sacrifice that even Time and love may never forgive.
