What Lily Carter wants most in the world is to attend Princeton University just like her grandfather. When she finally visits the campus, Grandpa surprises her: She has been selected to take the top-secret Legacy Test. Passing means automatic acceptance to Princeton. Sweet!<P>Lily's test is to find the Ivy Key. But what is she looking for? Where does she start? As she searches, Lily is joined by Tye, a cute college boy with orange and black hair who says he's her guard. That's weird. But things get seriously strange when a gargoyle talks to her. He tells her that there are two Princetons—the ordinary one and a magical one—and the Key opens the gate between them. But there are more secrets that surround Lily. Worse secrets.<P>When Lily enters the magical Princeton, she uncovers old betrayals and new dangers, and a chance at her dream becomes a fight for her life. Soon Lily is caught in a power struggle between two worlds, with her family at its center. In a place where Knights slay monsters, boys are were-tigers, and dragons might be out for blood, Lily will need all of her ingenuity and courage—and a little magic—to unite the worlds and unlock the secrets of her past and her future.
