Wizard-slayer. Blood of kings. Star-caller.

Wave bears many titles, but can any of them can save her?

War is brewing in the north while Wave is trapped in the wizards' dungeon. Buried underground, she struggles to maintain her grip on reality as the unending darkness seeps into her mind. But in the depths of the sinister castle, will Wave meet her most unlikely ally of all?

Jessandra returns home a triumphant starkin but is surprised by her father sending her to the capital in his stead. When she's introduced to the rebellion and their charismatic leader, her life becomes infinitely more precarious as she balances the many faces she must wear.

From different sides of Heredour, Wave and Jessandra fight for the rebellion in their own way. But will their efforts be enough to protect their people from the mad king—and an even greater danger coming towards them from across the sea?

In this spellbinding sequel to Unwinding the Spiral, true allegiances will be tested as an ancient enemy rises from the past.
