The Collector has all the magic, holds all the cards, leaving the Cruel King with nothing but blood on his hands.

For Wren, her only hope of saving her people now hinges on the one person she can never trust.

Can Wren and Calen kill two kings without destroying themselves and their tenuous love? Or will the lies and deceit be too much to overcome?
