Poison in Their Hearts: Castles in Their Bones #3

The final installment in the epic fantasy trilogy from the author of the Ash Princess series concludes the sweeping tale of three royal sisters bound by prophecy, betrayal, and destiny.

The triplet princesses of Bessemia—Sophronia, Daphne, and Beatriz—were born to seduce kings, conquer nations, and secure crowns. Yet their true fate was always far darker: they were destined to die, each serving their ruthless mother’s ambition to become Empress of all Vesteria. One sister, Sophronia, is already dead—murdered in her mother’s brutal quest for power—leaving Daphne and Beatriz to uncover the horrifying truth that they have always been nothing more than pawns in their mother’s imperial scheme.

Now divided by continents but united by purpose, Daphne and Beatriz must find a way to resist their mother’s control and forge their own destinies. With powerful allies—including King Leopold, Sophronia’s grieving husband; Violie, a spy who has turned against the Empress; and Pasquale, Beatriz’s missing husband, along with his lover Ambrose—the surviving princesses prepare for their final confrontation.

As ancient prophecies resurface and long-buried secrets threaten to unravel everything they believe about themselves, Daphne and Beatriz are forced to rely on every lesson their mother ever taught them about deceit, power, and survival. But the Empress always seems to be one step ahead, and the fate of Vesteria itself hangs in the balance.

In a world steeped in star magic, political intrigue, and tragic destiny, the sisters must defy fate, outwit their mother, and embrace the power in their blood—or watch their entire world fall to ruin.

This climactic conclusion delivers a blend of dark magic, sisterhood, sacrifice, and rebellion, bringing the saga of the Bessemian princesses to a breathtaking and emotional finale.
