The last girl on Earth...just got company.When Earth's sun turns red giant way ahead of schedule, the planet becomes a scorched wasteland, leaving most people dead. They're the lucky ones. Tora Reynolds is holed up alone in an underground shelter-her brilliant scientist father murdered, her mother and sister burned to death. She dreams of living on a planet with oceans, plants, and animals. Unfortunately, the oceans dried out ages ago, the only plants are giant cacti with deadly spines, and her pet, Trigger, is a gun-one of the bio-energetic weapons her father created for the government before his conscience kicked in. A lucky few escape the disaster by heading for space, but when family friend, Markus, returns to Earth with hired guns who want her father's weapons, Tora discovers her fellow survivors are even deadlier than the hostile environment. Her fury turns to fear when government ships descend in an attempt to kill them all. Tora forges an unlikely alliance with Markus and his rag-tag group of raiders, but must choose between saving herself by giving up the guns or honoring her father's request to save what's left of humanity from the most lethal weapons in existence. A thrilling post-apocalypse sci-fi read.
