Eldest Son of an Eldest Son by Fallon Walker

Prince Allard may have been born a girl, but he has known all his life that he is actually a boy and rightful heir to the kingdom as his father’s eldest son. However, his father, King Cederic, has chosen Allard’s brother to sit on the throne instead. With the help of his wizard mentor, Dwennon, Allard is able to convince his father to allow him to go on a quest to slay the dragon that killed Allard’s mother, Queen Belinda, when Allard was just a child. Should he succeed, the king would recognize Allard as his true son and heir. And so Allard must embark on a journey to slay the dreaded dragon Balsinew of the Glittering Eye. He must face down bandits, the beautiful but dangerous Prism Valley, and the Tunnel of Interminable Suffering in order to finally face the dragon and prove to his father that he is fit to be king.
