"Noor finds herself in the year 1177 in Jerusalem, during the Crusades. With the help of Sabeeka, Zainab, a girl who has the power to become invisible, and her local resistance group, Noor must once again find a feather belonging to the thunderbird before it burns, in order to prevent the world of the djinn from collapsing into the human world. Along the way, Noor helps the resistance group save hundreds of books and manuscripts from being burned"--OCLC.
