About this book

Book Summary

Perfect for fans of Powerless, Lightlark, and Red Queen, this heart-pounding romantasy forces a girl to make an impossible decision: watch the boy she loves get exiled for lack of magic, or pass her formidable powers off as his own.

In a world where dragons soar through the skies and magical abilities are an elite privilege, the ruling family of Ailm's Keep is on a knife-edge: Can their son Ionáin prove that he can channel magic, or will his entire family be cast out in disgrace?

Éadha, a servant girl who loves Ionáin, is shocked to discover shortly before the test that she can wield magic herself. It's extremely rare for a girl to have this talent, especially outside the few great Families. At Ionáin's moment of truth, when it's clear he is about to fail, Éadha makes a desperate gamble to save him from humiliation by pretending her magic is his, forfeiting her own claim to power.

Her decision sends them both to an academy of magic, where she must shield her secret from every grim Master and scheming apprentice—especially the handsome but enigmatic Gry. As Éadha enters this whirlwind of patriarchy, class, heartache, and jealousy, she also learns about magic's terrible cost—the human price that Channellers willingly pay to maintain their power.
