This book is very intriguing from the beginning. It is a vampirific twist, with plenty of romance, rebellion, and mostly adventure. It follows the story of Rose Hathaway, a dhampir at the boarding school St. Vladimir's. She is training to be a guardian of royal moroi Vasilisa Dragomir, who also attends the academy. These books keep you hooked until the end of the fifth book.
