Fairytale for Wizards Vol. 3 (novel) - Fairytale for Wizards, #3

His lifelong duty. Her unrelenting will. The end of a fairytale. In the land of wizards, there is a tale of love and magic that is whispered in hushed tones. It begins with a name: Azriel Esthera, bestowed upon her by the man who set her heart alight, Rhema Reshith. He was her master, her savior, and the one who filled her with inexplicable yearning. However, as Azriel delves deeper into the world of magic, she is faced with the fact that the one she loves may be capable of unimaginable horrors.
Her faith in the arcane arts begins to falter just as Rhema is forced to make a difficult decision: fulfill his sworn duty or follow the feelings that threaten to cast his heart into chaos. As her fairytale draws to a close, Azriel must choose whom to trust, where her loyalties lie, and whether to risk it all for the chance to see her own "happily ever after." True magic knows no boundaries, capable of changing destinies that have been written in the stars.
