The soon found themselves caught in the crossfire of a galaxy-spanning war between two disparate species: aggressive, milataristic humanoids known as Furs and passive, plantlike creatures known as Vines.
Into this volatile mix arrives the Crucible, a ship from Earth filled with military personnel who stand ready to help defend the colony. As they help consolidate the defenses and prepare for war, the original colonists learn that vigilance comes with a price.
