In this enthralling sequel to Kendare Blake's New York Times bestselling Three Dark Crowns, Fennbirn's deadliest queens must face the one thing standing in their way of the crown: each other.

Arsinoe, after discovering the truth about her powers, must figure out how to make her secret talent work in her favor without anyone finding out. And Mirabella, once thought to be the strongest sister of all and the certain Queen Crowned, faces attacks like never before--ones that put those around her in danger she can't seem to prevent.
