A House of the Road

When Staff Sergeant Ben Reuben's best friend, along with four other American solders, are kidnapped a few days after the D-Day invasion, Ben volunteers to rescue them. But this was no ordinary capture; the Nazis are waging an occult war, summoning an evil creature far more powerful than human soldiers or weaponry. Thankfully, Ben isn't alone on this mission; he is partnered with the mysterious, undead Ambrose, himself a powerful demon hunter. Ben and Ambrose must save the soldiers before the summoning is complete, and Hell breaks loose—literally.
