Home Signal (The Dominion Falls Series book 6) - Sarah Cass

When one of their own betrays them, Jane begins to lose faith in her friends, and herself.

She and Cole fight to reclaim their lives. With the pregnancy on tenterhooks, and the underage whore they take on as a ward, life doesn't show any signs of letting them rest.

The darkest hour comes just before dawn, and what should be a rescue turns into an hour of great sacrifice.

Jane is left with a choice - succumb to the darkness like her predecessor, Clara, or stand tall and fight.
