After the disaster of her coronation, Rina must go in search of the legendary Dragon's Heart necklace that has been lost for thousands of years. There were only two possibilities of where the powerful relic was located, the Land of Mysteries and the Human Realm. Never having ventured into either, Rina is forced to take along the vampire Nicolai and Damien, who of course bossed his way in. While trying to uncover the necklace's hidden location, Rina faces the hardest decision of her life, give in to the Bond or walk away from the only happiness she has ever truly felt.
