From the author of the New York Times bestselling Alex Rider series!
A year ago, thirteen-year-old David Eliot would have given anything to see the end of Groosham Grange and its ghastly teachers. Now he's on track to win the Unholy Grail, a cup of magical power rewarded to the star student. But a series of suspicious mishaps is closing the gap between David and the new boy, Vincent. It seems as though someone - or some thing - doesn't want David to win the cup and may even be threatening Groosham Grange's very existence!
