"Fae were supremely powerful beings, vessels for the most potent magic. It was why they were the self-appointed guardians of the Immortal Realm. Because they were the only beings powerful enough to keep all the others in check." Someone is dropping ancient mythical beasts through giant rifts in the fabric of the universe and, somehow, it is Ren Belling's job to stop them. Living as an abandoned Half Fae in a world that doesn't even know magic exists, Ren finds herself turning to an unlikely ally to heal the mortal realm and save her people. Lark is a banished Fae with a mighty power that he prefers not to talk about even though Ren can see the very glow of it emanating from him at all times. They strike a deal. He will heal her rift if she will help him back to his side of it. But dangers far worse than the minotaur or the gorgons await them on their journey. Ren knew it from the beginning. Her uncle had always warned her. The Fae are tricky. So what was she thinking?

Ren Belling made a vow to save her friends. Now she's stuck in her mother's hostile court, expected to play the role of Ariadne Dawnpaw's beautiful heir, the girl worth tearing the Divide apart to find. But the elixir demands a cost that she isn't willing to pay and she bends until she nearly breaks. Refusing a crown that is hers by birthright and a court that might have been home in another life, Ren feels utterly alone. Until she finds companionship from an unlikely source. She isn't willing to trust again, not yet. But her heart is more willing to give itself away than she logically wants to admit. Backed into corners again and again by her own mother's scheming, Ren lashes out in any way she can. And when that desperation sends her spiraling, she reaches out with the only thing that remains. Faith.

_War has arrived. With cryptic gods and ancient beasts in play, no one is safe._ It turns out freeing the god of time has consequences and Ren Belling is dealing with them. But fighting a war to guard the Divide and protect the mortal plane from her mother takes precedence. As court politics shift, Ren finds herself unsure of who she can trust. Sometimes, being on the same side of a battlefield doesn't mean you're allies. As she learns her world is much more affected by the forgotten deities than she thought, Ren comes face to face with a power that no one has ever held; a power that should have remained buried. Despite her best efforts to save her people, Ren has to admit that the more she learns of the Immortal Plane, the more she realizes... Secrets can kill.
