I just saved the boy I'm falling for from a gruesome death by a demon. And what does he have to say? I'm the key to opening the gates of Hell. I mean, a thank-you would've been nice. Or another scorching-hot, forbidden kiss. Either way, destiny will have to find someone else to torment, because I'm so done. Or I was, until my little sister starts cackling exorcist-style and stares at me with eyes that aren't hers. They're Marid's, the Greater Demon I just kicked back to the dark realm he came from. Possessing Ray whenever he wants is his ultimate revenge. The only way to break the tether between them includes a road trip through Hell, aka the Ather. I quickly discover nothing is as it seems in this place. Yeah, there are realms of terror, greed, and desire, but there's also peace, and a beauty I never knew existed . . . and it's eerily familiar. With each obstacle we encounter, I slip a little further into the chaotic energy of my growing dark powers. And when an unexpected betrayal hits me square in the chest, I freefall into them. Fate painted me as the monster of nightmares, and after this? Destiny is about to learn just how monstrous I can be.
