Iron hearted Violet

Princess Violet, unlike typical fairy-tale royalty, is plain, adventurous, and exceptionally clever. While exploring her castle with her best friend, Demetrius, she uncovers a hidden passage leading to a secret room. There, they find a forbidden book detailing an evil being trapped in their world. Violet, Demetrius, and the King's timid dragon may hold the key to its freedom or its ultimate defeat.
