Somer, Soiree, Sofie and Soher are sisters. Quadruplets. 21st century high school princesses. Literal princesses. 'Bred in captivity and under cover'- as they describe themselves. Their mother, la Reina de Harovar (the Queen of Harovar), has successfully, although with great effort, coveted them from media and publicity for eighteen years so no one outside the el Palacio recognize them by face and name. All for giving them an opportunity to attend a normal high school and learn alongside the people they are, someday, going to rule over.
But that 'someday' arrives sooner than any of them envisaged and now the Queen has declared a Royal Selection for her daughters, intending to get all four of them married to the right men before her time in the world proceeds to a halt.
But what if the Princesas are not who the Queen thinks them to be? What if they stumble upon their resolve and do exactly what their mother has trained them not to - fall for the wrong man?
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.
