Origins (The Lazarus War, Bk. 3)

For someone who has died and come back as many times as Conrad Harris, the nickname Lazarus is well-deserved. His elite military teams are specialists in death - running suicide missions in simulant bodies to combat the alien race known as the Krell. But now the Krell Empire has wreaked such devastation that military command is desperate for a new strategy. And Harris and his team are being sent on a mission that could finally turn the tide of the war.
