Hearts and realms will collide…Imprisoned by the Northern Institute, Arien’s hope of reuniting with Kole and her warrior family dwindles after hearing devastating news about Invicta and Xavier. So when the enigmatic Soaz offers her an irresistible deal—a blood pact for a few days of freedom—she takes the risk.

The desperate warrior uses her brief freedom to track down Kole, Xavier, and her friends at a hidden rebellion base. Though her choice of the brooding charcoal-winged warrior as her mate seems certain, the reunion reignites the love triangle, forcing Arien to confront her undeniable longing for both men.

But the blood pact’s invisible tether pulls her back to the Soaz, leaving her no choice but to abandon her angels. As the pact begins to alter her in dangerous, unpredictable ways, Arien fears losing control of herself. When the Soaz attempts to complete her transformation, she’s thrust into the void and the waiting arms of Sylvan—a phantom from her dreams and the Earthbounder from a different realm.

Hearts and realms collide in this otherworldly conclusion to Arien’s story as she fights to master her growing powers, uncover the truth behind her connection to the infamous stone—Sky Ice—and decide where her loyalty—and her heart—truly lie.
