The Forgotten Kingdom

With her dying breath, Morgan's mother cast a desperate spell to save her son from Duke Arnost, successfully wiping Morgan's and his kingdom's existence from the world's collective memory. Morgan has been paying the price ever since, as he struggles to free his people from an obscurity he has begun to despair of ever escaping.
 
Princess Caya has spent the past ten years living in isolation. Cut off from her father and her throne, she has watched her realm fall deeply under Arnost's sway. When her father dies, she faces the impossible task of returning to a court in which she has no allies and somehow finding a way to prove Arnost is a danger to the kingdom.
 
Before she can return, Morgan abducts her and takes her to his forgotten lands in the hopes of persuading her to help him bring Arnost to justice. Yet how can he hope to convince someone who has no memory of him, nor of the friendship they once shared?
 
But Caya does remember him—though that doesn't mean she trusts him. An alliance may be just what she needs to expose Arnost and save both their kingdoms, but how can she trust that Morgan doesn't intend to use her for his own ends?
