"Gia Kearns would rather fight with boys than kiss them. That is, until Arik, a leather clad hottie in the Boston Athenaeum, suddenly disappears. While examining the book of world libraries he abandoned, Gia unwittingly speaks the key that sucks her and her friends into a photograph and transports them into a Paris library, where Arik and his Sentinels-magical knights charged with protecting humans from the creatures traveling across the gateway books-rescue them from a demonic hound."--From publisher.
