Ari and Andreas know the O-Seven will never leave them alone. Ari is carrying Andreas's mortal child, but the vampire elders are convinced the child will be the first vampire baby and are out to posses it. Or kill it. Either way, Ari and Andreas will do anything to keep their unborn child safe, even if it means Ari has to go into hiding and leave Andreas exposed to the O-Seven alone. But then the O-Seven call on the Mahmo magic that can turn an elder into a winged killer, and each time Ari runs, they find her again. The only way to protect their child's future is to defeat the O-Seven, once and for all. And to do that, Ari will have to face the elders head-on in their castle stronghold deep in Germany's Black Forest...
