When Nathaniel Fludd was ten years old, he learned that his parents had gone missing during their expedition in the ice of the North Pole, and he himself would now live with his aunt. I must say that Aunt Fila turned out to be a very unusual woman. Firstly, she lives at home with an ancient, wise, talking bird, which everyone thought was extinct, and secondly, she herself is a cryptozoologist. Now Nathaniel will not only have to get used to his new home, but also get acquainted with all the intricacies of this amazing profession and... save the real phoenix!
