Loame Undon, known occasionally as "Flamebrand," has a very specific goal: to win the School Cup. What she hasn't accounted for: an ex-friend/more-than-friend who just so happens to be competing against her; a new crush who is definitely, one hundred percent unattainable; and, naturally, all of the usual obstacles that a fantasy heroine faces during a quest (fire-breathing piranhas, monks who swallow swords, and a creature half-tortoise, half-hare being only the beginning).
In the epic conclusion to the Devil's Deal series, Freya has one final chance to discover the full potential of her own power, and to use it to restore balance in the universe - once and for all. After the destruction caused by Roisin, Ferya and Torix come to terms with their losses and mistakes... And prepare for a final battle that will change everything.
