Captain Conrad Harris and the special operators he leads are fighting a war against a relentless, seemingly endless, horde of predatory alien creatures in this thrilling military science fiction series Jack Campbell, author of the Lost Fleet novels calls "a gripping read that moves at warp speed."
The soldiers of the Simulant Operation Program are used to dying, in the war against the alien enemy they face most of their missions end that way. Then they are given a new body and sent back into another battle only fit for the foolish or suicidal.
Their enemy asks no quarter and gives none. They do not sign treaties, they do not surrender. It is impossible to imagine what they even want, beyond mankind's total annihilation.
Now, a secret research station deep in the Quarantine Zone has gone dark without explanation and they must be sent back into the breach.
