This is the 3rd book in the Eternal Guardians. It is the story of Demetrius, an Eternal Guardian, and Isadora, the princess of Argolea. They are soul mates but do not want to be. He thinks since he is the son of Atlanta, evil, he is not good enough for her. She is shy and does what others say. The book takes you through their trails and discovery of their true selves. I would recommend this book and then other two books before this.
