When Panzers rip through the Ardennes, more than France is at stake.

On the heels of escaping Belgium, Evelyn Ainsworth is facing yet another invasion. The Wehrmacht is advancing faster than anyone expected, and all she wants is to reach England before the Nazis take Paris. With smuggled documents in her possession, and a fellow evacuee who carries secrets of his own, she must escape once again before France falls.

German bombers are wreaking havoc on Allied troops trying to reach the coast, and RAF Flying Officer Miles Lacey is frustrated. Despite flying daily patrols, his squadron has yet to engage the enemy. He's itching to get in the fight, but nothing can prepare him for what's coming.

As Panzers race to the Channel and the Luftwaffe dominates the skies, a storm of evil sweeps across the continent. Amidst the chaos and destruction, only the strongest will withstand the darkest storm.

And march into iron shadows.
