As Earth becomes an interstellar species, the ramifications hit home -- literally. Alien Cresperians scattered all over Earth; enemy Snappers seeking to expand their interstellar empire in any way they can. And Sergeant Edward "Bang" Bangler finds himself in the midst of two of the biggest battles he's ever been in -- a battle for his heart, and a battle for his home. In one mission of interstellar exploration, Earth finds perhaps its greatest allies and its greatest enemies, as they and the Cresperian race discover the inimical race of Snappers, a multiple stellar system empire of ruthless ferocity. Unfortunately, when the Snappers decide to expand their domain to include the Cresperian and Earth systems, the two civilizations must find a way to work together in order to prevent their own extermination.
