Her Hidden Fire

Brought to you by Penguin.

The first book in a searing new romantasy trilogy, perfect for fans of POWERLESS

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 Ionain, the heir apparent, channel magic, or will the family be cast out and replaced by a cruel master from a neighbouring land?

So when Éadha, a servant girl who loves Ionain, 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 Ionain’s moment of truth, Éadha makes a desperate gamble to save him, Ailm’s Keep, and ultimately herself.

As Éadha and Ionain enter a whirlwind of patriarchy, class, heartache and jealousy, they learn about power’s terrible cost – a price others willingly pay to maintain theirs.

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