The first full novel of the explosive new Joint Task Force 13 series! France, 1944. Allied forces are fighting in the hedgerows of Normandy, battling German armored forces. Hastily established airfields provided close air support and battle the Luftwaffe for control of the skies. One airfield is overrun by a supernatural horde, destroying every craft except a P-61 Black Widow, the allies new night fighter. Task Force 13, busy fighting the outbreaks of supernatural that always accompanies war, hasn’t an extra Marine to spare. A scratch crew of soldiers, airmen and one stray Marine pilot are given orders to seek out and destroy the horde of “gremlins” before they do further damage. Along the way they stir up something larger than they bargained for, and the war takes to the air.
