Stuart Horten (ten, but looks younger) is now the owner of a magician's workshop - except that without his Great-Uncle's Last Will and Testament, he can't actually prove it. Which is a problem, since someone else wants it as well; someone who has a lot of money.
The workshop contains seven magnificent stage illusions, but when Stuart starts to investigate them, he discovers that each is the gateway to a magical adventure, with a puzzle to solve, and a clue to extract.
As the clues mount up, the adventures become riskier. Friendship is strained, danger looms, and Stuart has to decide what sort of prize he really, truly wants.
