This Crimson Ruin

Synopsis

With thrilling steampunk action and swoon-worthy sapphic romance, This Crimson Ruin is a propulsive adventure following Nix and Kessandra, trapped in an underwater city and fighting monsters and time itself. From the Sunday Times bestselling author Rebecca Thorne.

Some depths were never meant to be explored . . .

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, the once-grand city now a ghost town in ruins. Aside from the occasional feral citizen, turned inhuman by a devastating infection, the city is eerily empty. And as Nix and Kessandra hunt for clues, Nix finds her fight for survival turning inward as a malicious entity attempts to tear her own humanity apart. 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.

This Crimson Ruin is the second installment in the Titan's Wrath Trilogy, perfect for fans of Arcane, BioShock and Tamsyn Muir's The Locked Tomb series.
