The Ziggurat of Doom - Doc Vandal Adventures, #6

Ancient Aliens in Mesopotamia! When the Christmas ball they are attending is thrown into chaos by the attack of power-armored Nazis, Doc and the team find themselves thrown into an adventure that will rewrite everything they know about human origins. Everything leads to the Great Ziggurat of Ur, where a column of fire reaches all the way to space. Will they find the answer before the world is destroyed? Sharks in the desert, winged aliens, robot skeletons, and biblical spaceships! It's all there in the sixth Doc Vandal adventure--The Ziggurat of Doom!
