From New York Times bestselling author MarcyKate Connolly comes the sequel to Twin Daggers, which follows Aissa and Zandria on their mission to understand their unique magical bloodline, as well as unite the Magi and Technocrats before their sworn enemy can turn the simmering hate between the two peoples into an all-out war.

Heartless Heirs:

Aissa has never felt so trapped and alone even with her sister and friend by her side. Zandria—once her other half—has become cold and inflexible after her time in the Technocrats' dungeon. Their friend Remy may still side with his father, a Magi leader who refuses to believe his spymaster has turned traitor. And Aissa herself is now an enemy of her Magi people after falling in love with—and binding her heart to—Aro, a Techno prince who puts all their lives at stake.

Aissa is determined to uncover the secrets of the Alchemist Alliance that created her and Zandria's unique magical powers ... as well as learn whether the Alliance's research holds the key to healing the rift between the Magi and Technocrats after centuries of war. But with her people preparing for battle, it will take more than lost spells and hidden secrets to accomplish her goal. Especially as the bond between her and Aro grows deeper and threatens everything Aissa has ever believed.
