The Heart of Valor: a Confederation Novel (Valor Novel)

Staff Sergeant Torin Kerr's goal is to keep both her superior officers and her troops alive as they face missions throughout the galaxy.

The major was reduced to little more than a brain and spinal cord in his last combat, and now he and his doctor are eager to field test his new body.

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...
