Jason Bodger is the boss of class 4Z and the terror of student teachers, until the fateful day when 4Z visit the Priory. While the rest of the class see an ancient building with a few medieval relics, Jason sees a girl walking towards him on a non-existent beam, and is never the same again.

Eight centuries before, Mathilda de Chetwynde is born in her father's castle. Ignored by her sisters, she grows up beautiful and daring, roaming the forest until her father returns home from the Crusades with his villainous heir, Antacill.

Then begins the series of disasters that will consign Mathilda to a convent and bring her so strangely into contact with Jason Bodger ...

Gene Kemp always writes superbly about dreadful boys and independent-willed girls. Here, in the fabulous and strange story of Jason Bodger and the Priory Ghost, Jason and Mathilda meet in a version of the Middle Ages that has a wild and vivid comic poetry all of its own.
