But she is out for vengeance with a new strategy, one she must keep a secret from Caine. Turns out, Rosalind has powerful magic of her own. As Rosalind develops her terrifying powers, she must control her darkest impulses. If she can’t gain reign in the chaos in her mind, the world will fall under the nightmarish control of her cousin’s dark army.
