Reborn into a life she thought she'd already lost, Lea Yamaguchi remembers every bruise, every betrayal—and every cruel laugh that followed. Once the cherished daughter of a famed marshal, she was betrayed by her half-sister, handed like a plaything to Lord Knox Rocha, and left to die while Knox’s favored bride took her place. This time Lea will not be a victim. When she is dragged into the world again—strung up on a mountain ridge, the sun baking her skin—Lea’s only certainty is the memory of a carved-out heart and the vivid pain of being discarded. Fate hands her an unlikely ally: the sickly but uncommonly kind Prince Kellan Fitzpatrick, who once traded his life to save hers. Bound to him by debt and strange affection, Lea plays a dangerous game at court and on the battlefield: hide her knowledge, seek the antidote to a legendary toxin, and unearth why her parents truly died. Each truth she peels back reveals a keener blade: that Knox’s cruelty is not mere madness but a well-crafted vendetta—and that the stakes are more than a single marriage. Heart of Frost, Crown of Ash is a historical revenge romance about second chances, poisoned loyalties, and the quiet, stubborn courage of a woman who refuses to be erased. Blood will be repaid, hearts will be reclaimed, and the winter that once froze Lea’s fate will be rewritten as her proving ground.
