To fight the war, they must find a legendary commander.

For a hundred years, the Planetary Union of Nine has grown soft and complacent. They believed the post-human Aternien Empire was gone for good. Now, they're a ghost story relegated to the history books.

But Major Carina Larsen of Union Military Intelligence knows they're wrong.

When an unknown warship obliterates a Union frigate on the frontier, Major Larsen's worst fears are realized. The Aterniens have returned, stronger and deadlier than ever.

Entirely unprepared to fight the impending war, Major Larsen is given a covert mission to find the one man who can stop the oncoming storm.

Master Commander Carter Rose is a legend—an augmented super-soldier who won the last war. Now living a quiet life in exile on the lawless forest moon of Terra Nine, Carter wants nothing to do with the Union.

But the Aterniens don't care what humanity wants. They want revenge. And the only thing standing between humanity and extinction is a hidden commander whom Major Larsen must track down, before it's too late.

Then comes the real question. Will Master Commander Rose decide that his betrayers are worth saving?

Step into the Aternien Wars universe with Hidden Commander, an explosive military sci-fi adventure featuring epic space battles, augmented heroes, and a relentless post-human enemy determined to reclaim the stars.
