This Crimson Ruin: The Titan's Wrath Book 2

Death might be the only escape . . .

When Sergeant Nix Marr signed up as her ex’s bodyguard for a trip to the domed city of Fall, she doubted she’d return alive. But neither woman could have predicted the cataclysmic event that stranded them both beneath the ocean.

Worse, Fall has been completely abandoned, ruins of a once-grand city. Aside from the occasional infected citizen, there’s no indicator where the rest of Fall’s population went. And as Nix and Kessandra hunt for clues, a deeper evil prods Nix’s own mind.

With Fall’s iconic dome flooding and every answer creating more questions, the pair may have to descend deeper than they ever imagined to survive.
Welcome to Fall.
