Desperation grips humanity in this far future. For twelve years, they had fought a ruthless enemy, and for twelve years, they had lost. Their worlds, decimated; their fleets, incinerated; and time is running out before the entire human race is extinct. Captain Sean Mallory, Captain of the Erebus, leads a battered crew toward one of the last human colonies in the wake of a brutal attack. For the entire war, he has studied the enemy, viewed their tactics up close, and feels he has the answer to finally turn the tide of the war. Yet treacherous acts threaten to continue the mass genocide as Captain Mallory works to implement his plan to save humanity and the crew of the Erebus.
