Another Boring Summer Holiday is a traditional young person's adventure story, but set within the modern digital computer age of today. Rachel Coakly and her long suffering younger brother John find themselves at the start of another wet school summer holiday with absolutely nothing to do and no vacation to look forward to. However, a chance meeting on one of their dad's boring day trips to an ancient ruined abbey brings them into contact with the handsome David Rawsthorne and his younger sister Sally. Is there something sinister going on within the midst of the old ruins? Together they explore the area further and are drawn into the long running feud between the leader of a secret sect and the director of a devious financial company. As the plot unfolds they uncover a political conspiracy of astronomical proportions. But who will save the day, and more importantly, who can Rachel really trust?
