Publisher's Synopsis
An extra present was delivered to William on his ninth birthday. A box was found on his doorstep and when William opened it he saw a watch and a note: "This watch has magic powers that only you can use. If the watch face lights up in blue then press it and you will be transported to anywhere that your help is needed". William discovered that by pressing the watch when it lit up he became invisible and could fly to places where his help was needed. William enjoys many adventures as a superhero while wearing the watch.
