Publisher's Synopsis
Claudia Ding thinks that she is just an ordinary child living a boring life. However, she soon finds herself entering a world that is very different to her own. A world where all the echoes of the past mingle with the present in the historical city of York. A world where on any street corner you may find Roman soldiers or 2nd World War pilots. A world where you are just as likely to meet monks and pirates as you are kings and queens. A world where long lost buildings can reappear in an instant and disappear again just as quickly. Join Claudia and her friend Mathilda as she searches the Echo World for the mysterious keys which will help her save the city from a dark enemy that threatens it. Along the way she has to solve clues, fight dangers and learn about the history of the city directly from the people who lived it.
