It's vacation again - time for William, Mary, and Alice to return to Golden House. They've made a solemn vow not to speak of anything that happened on their last visit to Uncle Jack's home.

It is alice who discovers the Dark and Dreadful Path, Alice who is irresistibly drawn to the ancient yew tree. And it is Alice who finds the door in the tree - leading to the secret hiding place of the Magician. It wasn't a dream!
Soon they've become the Magician's students, led by the kestel, the badgers, and the dog into the most perilous assignment of all....
