Victory at Normandy (Soldier Dogs, Bk. 4)

The most famous invasion of WWII is about to start. Henri's on a special mission for the French Resistance, but his plan goes astray when Henri finds a lost parachute dog, Ace, and Elle, a war orphan who needs his help. The dog belongs on the front lines with his handler, and Henri is the only one who can reunite them. Ace may be small, but he's determined to help Henri stay safe. And when they're captured by enemy forces, his skills may be the only thing that can help them escape.
