Martin and Dan love frightening the younger children at school with scary ghost stories. But then Kirsty arrives. Kirsty claims that she can actually see ghosts - and she sees them in so many places that everyone becomes petrified. Then a mysterious virus sweeps through the school. Martin is still sure she is lying. After all, ghosts don't exist - do they?
Dan and his friend really enjoy creating ghost stories around the school. However, when Kirsty arrives as a new student and actually sees the ghosts, the boys suddenly feel uneasy about everything! Very engaging, spooky story that will be gripping or the young readers.
