"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"-- Publisher's description.
