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 commands the Argus. She has no resources, no comms-nothing, except for the soldiers that no one wanted. Her ace in the hole could be Cavalon Mercer--genius, asshole, and exiled prince who nuked his grandfather's genetic facility for "reasons."
She knows they're humanity's last chance.
