If he has the ability to wield magical powers, everyone will rejoice – especially the girl who loves him. But what happens when they realize she has the gift?

In a world where dragons stalk the skies and magical abilities are an elite privilege, the ruling family of Ailm’s Keep is on a knife edge: can Ionáin, the heir apparent, channel magic, or will the family be cast out and replaced?

So when Éadha, a servant girl who loves Ionáin, discovers that she can draw power, she finds herself in grave danger. It’s extremely rare for a girl to have this talent, and certainly never outside the great families. At Ionáin’ s moment of truth, Éadha makes a desperate gamble – a trick – to save him, Ailm’s Keep, and herself. But how long can this ruse last?

Sent to the very heart of the Masters’ control, Éadha and Ionáin enter a whirlwind of patriarchy, class, jealousy and heartache, as Ionáin must make a suitable match and Éadha finds herself undeniably attracted to the enigmatic Gry. Here they also learn the true, terrible cost of channelling magic – a price the Masters willingly pay.

How far would you go to empower the one you love?
