Against The Depths — Kip Nelson

Held against their will, Grace and her patrol are at the mercy of the sewer-dwellers. The longer they remain captive, the harder it will be to find food. Even if they break free, there's no guarantee they'll survive the labyrinth of sewers and secrets that lie ahead.

Back at the settlement, Mack anxiously awaits Grace's return. New Haven's future hinges on Grace's mission. If things go awry, he'll be forced to make face the biggest challenge yet -- one that will change everyone's life.

Will Grace's fight for freedom entered her into a deal with the devil?
