Infinity's Edge: Infinity's Edge, cartea 4

Sixty years ago, a warning from the stars launched a secret plan to prepare humanity for first contact. Now a hostile alien race knows Earth exists, and the nations of the world must choose: unite against a common enemy or face invasion alone.

Far beyond known space, Commander Kaylan Farrow and the crew of the Athena may be humanity's last real hope. They are following a signal left by an ancient race whose wars nearly destroyed the galaxy-a trail Zack Quick believes could lead to something capable of stopping the Xiiginns. Every jump takes them farther from home and deeper into territory even their allies have never mapped.

But the Athena is dying. Its hull is cracking, its systems are failing, and the crew can no longer keep pace with the damage. Turning back may be their only chance to survive. If Kaylan abandons the search, Earth will face the Xiiginns with a way to stop them.

When the signal draws them to a hidden place beyond the edge of known space, Kaylan must keep her crew alive long enough to learn why humanity was chosen-and what the last survivors of an ancient war left behind.

Infinity's Edge is the fourth book in the Ascension series, a first-contact space opera of ancient alien mysteries, interstellar war, and humanity's struggle to find its place among the stars.
