Bridgerton meets Pacific Rim in this sapphic fantasy romance where a feisty noblewoman must team up with a disgraced mecha fighter to win her own hand and save her family from fortune hunters.

In an alternate Regency England where marriage to eligible noblewomen is decided by deadly mecha dueling tournaments, half-Chamorro bluestocking Lady Wilhelmina Applewhite will choose her own destiny, thank you very much. But when her father’s sudden death leaves Willa as his sole heir, her hand in marriage becomes the upcoming Season’s grand prize.

Determined to seize her fate—and protect her little sisters’ freedom—Willa shocks the ton by hiring a Bloodsworn fighter to compete for her own hand in the deadly gladiatorial duels of the Season. Except the only one mad enough to even consider fighting for Willa is rakish Thomasin Drake, the first and last woman to have ever fought in a Season . . . until her final duel ended in defeat and disgrace.

But if Willa isn’t careful, she might lose her most valuable possession—her heart—to Thomasin before the Season duels are over. And in a world where marriage is a matter of life and death, falling in love is the last thing she can afford.
