Can two Terran Alliance Marines come to term with impending parenthood? In the distant future, human kind has spread out into the universe--way out. Among the Terran Alliance Marines assigned to a distant sector is Caden Roth, a medic, and pilot Benjamin Magnys. Caden and Ben meet when Ben is injured during an alien raider attack. Ben is from Gaddo, a colony so remote and with such extreme environmental conditions, that the colonists there were forced to alter their genome in order to survive and to ensure a healthy gene pool. After the kind of bad day that only emergency medical people can have, Caden and Ben meet again for a drink. One thing leads to another and they end up in bed together, which eventually evolves into a fledgling relationship. However, antibiotics and altered genetics throw the new lovers a definite twist. Going home to tell the parents that they are pregnant is going to be interesting.
