The Enemy Revealed: The Last Hunter, Book 4 (Unabridged‪)‬

Victory, but at what cost?

Commodore Jack Romanoff and his crew won the battle for New Copenhagen but lost their quantum drive in the fight. Now they must free the human prisoners and strengthen their defenses before the Locusts trap them.

If it’s not already too late.

Only the alien hyperdrive they recovered offers a chance to get a new quantum drive and more missiles before time runs out. To master it and solve the mystery of the invasion, they must open a dialog with the aliens and get their willing cooperation. Somehow.

With no time to waste, they’d best be persuasive.
