Captain America: The Ghost Army, A Graphic Novel by Alan Gratz

In this thrilling adventure set during World War II, Steve Rogers’s (aka Captain America) and his young sidekick, Bucky Barnes, encounter a threat like none they’ve ever seen—a Ghost Army. The dead of this war and wars past are coming back to life, impervious to bullets, flames or anything else the Allies throw at them. The armies rise from the ground in the night and seem to disappear without a trace.

How can Cap and Bucky fight something that’s already dead? And just what does the mysterious Baron Mordo—sitting in his castle atop nearby Wundagore Mountain—have to do with this?
