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. There is a thin wall between our world and that of the Fae and, during times of war, it is easily stepped through.

In modern America, they are the men and women of Joint Task Force 13, those who have proven they have the mettle to confront soul blasting otherness on the battlefield. This unit, this organization, though, has been intertwined with our country since its birth. The name changes, but they are always there, ready to answer the call. Unknown, seeking no glory, asking no reward. They hold the line ... BETWEEN HEAVEN AND HELL.
