A darkly addictive romantasy debut about a girl who sacrifices everything to buy the dangerous magic that could save her sister - the first in a trilogy perfect for fans of The Foxglove King and Throne of Glass.

On the mist-shrouded Isle of Eireann, buying magic comes with a price.

But when her beloved older sister is gravely injured, Maeve risks everything to buy the forbidden magic that might save her. In exchange, Maeve trades her life to a ruthless and dangerously alluring rebel leader. Bound to do his bidding, Maeve finds herself thrown into a deadly competition to become the next queen and stand beside a prince rumoured to be more brutal than his tyrannical father.

With the isle on the brink of war, trust and survival come at a terrible cost-one that will tear Maeve's world, and her heart, in two.

What would you sacrifice to survive?
