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.
