Two years ago Will Starling and Anna Wilder saved London from VIPER and the Stones of Fire. Now Will, drafted into the SOE, has joined forces with the French Resistance. Though he still has not regained his memories, he has not forgotten his pledge to find and rescue his sister, Rose. With a suspected mole in the SOE, it seems no one can be trusted. And VIPER have plans to unleash the forces of evil in the Red Storm, bringing mass destruction on a scale even the Nazis haven't dreamt of. Meanwhile Rose, drugged to dull her kinetic powers, is the key to VIPER's masterplan, and her time is running out.
