When Tim discovers a man badly hurt on a beach, his sun-kissed relaxing holiday in the Seychelles takes on a more dangerous twist. He and Grk are the only ones, it seems, who want to know what happened. They find themselves speeding towards a well-guarded private island, and single-handedly foiling a dastardly plot threatening the local endangered giant tortoises.
Our children enjoy listening to the Grk books whilst we're driving. The plots are inventive and gripping with colourful locations. This book in the series may be a little dark for younger children but was well read by the narrator and held the whole families attention during a long car journey.
