#1 New York Times bestselling author Kendare Blake returns with the highly anticipated third book in the Three Dark Crowns series! And while Arsinoe, Mirabella, and Katharine all have their own scores to settle, there is another queen stirring things up on Fennbirn Island.

Queen Katharine has waited her entire life to wear the crown. But now that she finally has it, the murmurs of dissent grow louder by the day. There's also the alarming issue of whether her sisters are actually deadâ??or if they're waiting in the wings to usurp the throne.

Mirabella and Arsinoe are alive, but in hiding on the mainland and dealing with a nightmare of their own: being visited repeatedly by a specter they think might be the fabled Blue Queen. Though she says nothing, her rotting, bony finger pointing out to sea is clear enough: return to Fennbirn.

Jules, too, is in a strange placeâ??in disguise. And her only confidants, a war-gifted girl named Emilia and her oracle friend Mathilde, are urging her to take on a role she can't imagine filling: a legion-cursed queen who will lead a rebel army to Katharine's doorstep.

This is an uprising that the mysterious Blue Queen may have more to do with than anyone could have guessedâ??or expected.

Don't miss Five Dark Fates, the thrilling conclusion to the series!
