Tyranny of the Heart
"This is a story that I know you haven't heard. This is my story."
Aurina, a fearless, but kind-hearted woman, has been best friends with Caspian her whole life. But after both her father and Caspian's father dies, their lives are flipped upside down upon the arrival of four fairy tale figures. As Aurina comes to terms with this new way of life, she finds herself being torn between promises and what her heart tells her.
Basically, it's just retelling of the movie, Prince Caspian, but in a different way.
