At seventeen, Ren Pernell knows the meaning of tragedy.

But then, a year after losing her parents, Axel Knight walks through the door and changes everything. Strange creatures start to appear, her best friend suddenly finds her irresistible, and an undeniable, unexplainable bond with Axel threatens to drive her insane. She knows he's the key. There's something he's not sharing, and she's determined to find out.

Demanding answers, she finally learns the truth: everything she ever believed is an illusion. Caught in a centuries-old blood feud between races she never knew existed, Ren discovers her true destiny. She's the chosen one, the Echo, preordained to end the bloodshed.

There's just one catch—in order to save those she loves and a homeland she's never seen, she'll have to die.

With the clock running out, she'll have to navigate a new world of betrayal, lies and deceit. If she can forgive, finding love even in the darkest places, she just might be able to escape the prophecy. But how much is she willing to sacrifice for a cause she didn't know she was part of? And what will it take for her to be free?
