Centauri War

Pax Solis #4

by B.V. Larson, David VanDyke

Humanity reaches for the stars—and something reaches back.

Lieutenant Commander Alex "Flex" Callahan leads Operation Magellan, humanity's first mission beyond the solar system. As the only Pathfinder who can navigate the dimensional rivers between stars, he must guide an uneasy alliance of humans, Lizards, and Vraath warriors to Alpha Centauri. Their establish a foothold among alien suns before their enemies can stop them.

But The Cure has not forgotten its defeat at Venus. The crystalline horror that sought to "perfect" humanity has been waiting, building, spreading through the Centauri system like a cancer. Now Flex must fight a war on two fronts—against an enemy that corrupts everything it touches, and against the political forces that would sacrifice the mission for their own gain.

When The Cure launches its final assault, Flex faces an impossible retreat and abandon Earth's dream of reaching the stars, or strike at the heart of the enemy's power in a dimension where no one can survive.

CENTAURI WAR is the fourth pulse-pounding installment in the Pax Solis series—where humanity's greatest triumph could lead to its destruction.

Nice twists at the end

I liked that the author didn't take the routine path in the story. Some unusual twists but believable. Some new insights into how things started with the cure and the blight. Can't wait for the next book.

Hard to put down

This final book in the series was the best yet. Think Tom Clancy meets Star Wars and Star Trek. Will there be more in the future? I hope so.
