Military Stars / Tobin Kerr

Staff Sergeant Tobin Kerr was a battle-hardened professional. So when she and those in her platoon who had survived the last deadly encounter with the Others were yanked from a well-deserved leave for what was supposed to be "easy" duty as the honor guard for a diplomatic mission to the non-Confederation world of the Silsviss, she was ready for anything.

Confederation's investigation of a seemingly abandoned alien spaceship.

It's supposed to be an easy assignment -- after all, Crucible was set up to simulate battle situations so recruits could be trained safely. But Torin's barely on-planet when someone starts blasting the training scenarios to smithereens...

Unexpectedly pulled from battle, Gunnery Sergeant Torin Kerr of the Confederation Marines finds herself in an underground POW camp that shouldn't exist, where her fellow marine prisoners have lost all will to escape. Now, Torin must fight her way not only out of the prison, but also past the growing compulsion to lie down and give up-not realizing that her escape could alter the entire course of the war.

Having left the Marine Corps, former Gunnery Sergeant Torin Kerr is attempting to build a new life with salvage operator Craig Ryder. Turns out, civilian life is a lot rougher than she'd imagined. Torin is left for dead when pirates attack their spaceship and take Craig prisoner. But "left for dead" has never stopped Torin. Determined to rescue Craig, she calls in her Marines. And that's when her mission expands to stopping the pirates from changing the balance of power in known space. (Amazon.com)
