Cursebreakers (Book 2): A Heart So Fierce and Broken, Brigid Kemmerer

Find the heir, win the crown.
Win the crown, save the kingdom.

Finally free of the curse that almost destroyed him and his kingdom, Prince Rhen is ready to take the throne of Emberfall. But rumours are rife that he isn’t the rightful heir and that his alliance with “Princess” Harper is nothing more than a farce.

Grey is the true heir to the throne but he has no desire to claim it. When he is taken to Ironrose Castle by force and imprisoned, he forms an unexpectedly close bond with an enemy princess. And as his feelings for her grow stronger, Grey is forced to decide whether he will take a stand against Rhen for the crown he never wanted.
