The Evolved. The Evolved, #4

Two centuries ago, Earth forced a rebellious party of space colonists to flee the solar system in a jury-rigged habitat never meant for interstellar travel. Now they've come roaring back. Existing as a Group Consciousness, the race calling itself "the Evolved" quickly sends the navies of Earth and her colonies reeling. Fast Cruiser Captain Arvada Sattar, of the Peregrine colony, fights an isolated guerilla war against the conquerors.
But she faces condemnation from her own government, which sees surrender as the only option. Meanwhile her brilliant tactical officer, Sahan Kotori, finds himself increasingly drawn to explore an artifact of the Group Mind - a bizarre and hostile landscape where a single misstep will leave behind nothing but an eternal scream. The fourth book of an epic science fiction series, The Evolved carries space war into a future where the mind becomes the greatest weapon, yet can never unshackle itself from the heart.
Experience this gripping and unique saga on the far frontiers of human experience.
