Staff Sergeant Torin Kerr's goal is to keep both her superior officers
and her troops alive as they face missions throughout the galaxy. But
she's been sidelined with endless briefings and debriefings for a
while, so she jumps at the chance to go to Crucible - the Marine Corps
training planet - as temporary aide to Major Svensson. 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.
