This Crimson Ruin: Thrilling science fiction adventure with sapphic romance from the Sunday Times bestselling author

Thrilling steampunk action with 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.

Death might be their 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 enters 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.

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.
