Someone is trying to destroy David Eliot's school. A year ago, he'd have been happy to see the end of Groosham Grange and its ghoulish teachers.

Now, he's on course to win the Unholy Grail, a cup of magical power presented to the star pupil.

But a series of suspicious mishaps sees the gap between David and new boy Vincent King narrow alarmingly.

Someone, it seems, is trying to stop David winning - and, worse, threatening Groosham Grange itself!
