Books like Valor's Trial

The rousing military adventure (Locus) continues with a brand new Valor novel. Gunnery Sergeant Torin Kerr is a Confederation Marines marine. She's survived more deadly encounters and kept more of her officers and enlistees alive than anyone in the Corps. Unexpectedly pulled from battle, Torin finds herself in an underground POW camp that shouldn't exist, where her fellow marine prisoners seem to 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 sit down and give up - not realizing that her escape could mean the end of the war.
