When archaeologist Ursula Morrow accidentally infects herself with an alien parasite, she fears she may have jeopardised her career. However, her concerns become irrelevant when Earth is destroyed, billions die, and suddenly no one needs archaeologists anymore... Two years later, she's plucked from a refugee camp on a backwater world and tasked with retrieving the artifact that infected her, as it just might hold the key to humanity's survival. With time running short, and the planet housing the weapon now situated in hostile territory, she realises she's going to have to commit an act of desperate piracy if she's going to achieve her objective before the enemy's final onslaught.
