Valor's Strike by Kal Spriggs

Jiden Armstrong faces a threat bigger than any she has ever seen before. The Star Guard dominate human space, and they have decided to destroy the Centurions. They plan to throw the Centurions into battle, again and again, until none are left.

The Centurions are left with a choice… to bow to the stronger forces of the Star Guard or to strike a first blow and be free.

It falls to Jiden to make that first strike, to lead a commando raid to seize the ships needed to fight the alien Culmor Empire. Because if she doesn’t, then her people, her planet, and their very way of life will vanish forever.
