"The third book in a fast-paced time-traveling fantasy adventure trilogy centered on a young orphaned Palestinian girl who starts in the present and must go back in time to save the world. In the third and final book of the Thunderbird trilogy, Noor finds herself in Byzantine Jerusalem, in the year 638 CE, where the city is under siege. She is joined by Sabeeka, the djinn who takes the form of a cat, and meets the twins Helena and Julian, who have the power of healing. The four team up to find the thunderbird. But before they can, they are swallowed by a giant wormlike creature called a bakasola, which takes them to the world beyond the wall that separates the world of the djinn from our ordinary human world. From the terrifying, dark, gloomy world of the bakasola, Noor and her friends are rescued and delivered to the colorful and peaceful world of the sakarik, where they discover the bakasola are stealing the golden liquid that keeps the sakarik alive. Will Noor and her friends rescue the sakarik and return to the human world in time to find the last two thunderbird feathers that will save the world?"--Publisher's website.
