Changes

The author Helen Moss is well-known for a series of mysteries for younger readers, including [[Adventure Island: the Mystery of the Drowning Man by Helen Moss|Adventure Island: the Mystery of the Drowning Man]] and [[Adventure Island: The Mystery of the Whistling Caves by Helen Moss|Adventure Island: The Mystery of the Whistling Caves]] but this book is aimed at readers at the upper end of the confident reader scale and young teens. Not only is it twice the length of her previous thrillers, but the protagonists go off to explore on their own in a foreign country and find themselves in seriously life-threatening situations more than once. It is definitely a book for both boys and girls, and really should not be missed by any fan of history or adventure: it is excellent!

Two more good books which combine edge-of-the-seat adventure with codes, puzzles and mysteries are [[The Forbidden Stone (The Copernicus Legacy) by Tony Abbott]] and [[Ruby Redfort: Catch Your Death by Lauren Child]]. You might appreciate [[The Sword Thief (The 39 Clues) by Peter Lerangis]].
