Unter — J. Channing

As D-Day hangs in the balance, Sgt. Jim Thompson leads a daring airborne operation deep into Nazi Germany. His men must secure the alien chrono-device known as Der Dom, and then somehow defend the mountain until relieved. Under constant siege, they have only risky, experimental methods of communicating with RAF Tempsford. If Thompson's men are beaten, handing Der Dom and its unique, alien prize to Hitler, an Axis victory in Europe will surely follow. Among the embattled defenders is Professor Yannis Miller, the Israeli mathematician who risked everything to deliver a terrible warning to MI5, and was dismissed as a fantastical crank. Caught now between a stubborn machine with illegible symbols, and an SS Division poised to eradicate the paratroopers from German soil, Yannis recruits the unflappable Jillian Qualmes to help decode the device, and perhaps give them a way out. Captured but defiant, Kristock Keck plots a bloody escape, determined to lead the SS to victory in the mine's heavily-defended galleries. To stop him, men from past and future must fight shoulder-to-shoulder, all while the Nazis hurry to prepare the most terrible and lethal response. Set in the grandeur of a giant salt mine, amidst the workings of an alien spacecraft and in the air over Germany, Unter continues the epic story of Hitler's last and greatest roll of the dice.
