Manfred von Richthofen, the famed Red Baron, leads his elite group of pilots into one of the bloodiest battles of the Great War. But there is another threat in the skies besides British and French fighters . . . something that is not human. It kills swiftly, and the few survivors it leaves are driven mad with fear. As hundreds of thousands of men slaughter one another across Flanders, the Red Baron and his Flying Circus are tasked with tracking down this new foe. A creature whose origins are unknown, whose abilities are beyond anything the German fliers have ever faced. The Red Baron must fight this winged menace while dealing with the after effects of a traumatic injury. But he must find a way to overcome his condition and destroy this monster, otherwise it will not only be his squadron that pays the price. It could spell defeat for his entire nation.
