The Divide. It's the edge of the universe. Now it's collapsing--and taking everyone and everything with it. The only ones who can stop it are the Sentinels--the recruits, exiles, and court-martialed dregs of the military. At the Divide, Adequin Rake, commanding the Argus, has no resources, no comms--nothing, except for the soldiers that no one wanted. They're humanity's last chance.--Provided by publisher.
