His father and uncles are enchanters, his mother a powerful sorceress, yet nothing seems magical about Christopher Chant except his dreams. Night after night, he climbs through the formless Place Between and visits marvelous lands he calls the Almost Anywheres. Then Christopher discovers that he can bring real, solid things back from his dreams. Others begin to recognize the extent of his powers, and they issue an order that turns Christopher's life upside down: Go to Chrestomanci Castle to train to be the controller of all the world's magic.

Someone at Stallery Mansion is changing the world. At first, only small details, but the changes get bigger and bigger. It's up to Conrad, a twelve-year-old with terrible karma who's just joined the mansion's staff, to find out who is behind it. But he's not the only one snooping around. His fellow servant-in-training, Christopher Chant, is charming, confident, and from another world, with a mission of his own—rescuing his friend, lost in an alternate Stallery Mansion. Can they save the day before Conrad's awful fate catches up with them?

Cat doesn't mind living in the shadow of his sister, Gwendolen, the most promising young witch ever seen on Coven Street. But trouble starts brewing the moment the two orphans are summoned to live in Chrestomanci Castle. Frustrated that the witches of the castle refuse to acknowledge her talents, Gwendolen conjures up a scheme that could throw whole worlds out of whack.

There are good witches and bad witches, but the law says that all witches must be burned at the stake. So when an anonymous note warns, "Someone in this class is a witch," the students in 6B are nervous—especially the boy who's just discovered that he can cast spells and the girl who was named after the most famous witch of all. Witch Week features the debonair enchanter Chrestomanci, who also appears in Charmed Life, The Magicians of Caprona, and The Lives of Christopher Chant. Someone in the class is a witch. At least so the anonymous note says. Everyone is only too eager to prove it is someone else—because in this society, witches are burned at the stake.

Tonino is the only person in the famous Montana household who wasn't born with an instinct for creating spells, but he has other gifts. His ability to communicate with cats just might help defend the city of Caprona against a mysterious enchanter—but only if Tonino can learn to cooperate with a girl from the hated Petrocchi family of spell-makers.

Cat Chant and Marianne Pinhoe have discovered something exciting—something truly precious, very strange, and valuable. An egg. An egg that has been hidden away in an attic for who-knows-how-many years. An egg protected by some strong "Don't Notice" spells. An egg that Marianne gives to Cat, even though he lives at nearby Chrestomanci Castle. Chrestomanci himself, the strongest enchanter in the world, is sure to be interested in the egg—and interference from the Big Man is the last thing Marianne's family of secret rogue witches wants. But how much longer can the Pinhoes keep their secrets? Gammer, the leader of the clan, has gone mad, a powerful bad luck spell is wreaking havoc, and there's an unexplained plague of frogs. Not to mention the mysterious barrier Cat finds in the forest. Marianne and Cat may be the only two who can set things right. But first Marianne must accept her own powerful magic, and Cat must uncover the secrets behind the mystical Pinhoe Egg. In this new Chrestomanci book, Diana Wynne Jones is at her most magical.

Dapper, debonair, and wise, the great enchanter Chrestomanci has nine lives and a strong personality as well as strong magic. That personality reverberates in each of these four dazzling stories. A warlock tries to escape Chrestomanci's justice by fleeing to another world-with hilarious results. Cat Chant and Tonino Montana reluctantly join forces when Chrestomanci sends them on a visit that turns suddenly dangerous. The youngest best-selling dreamer needs Chrestomanci's help when she finds she can't dream anymore. And as the gods of an ever-so-orderly world try to destroy the young Sage of Dissolution, Chrestomanci lends a hand. Like Chrestomanci himself, acclaimed author Diana Wynne Jones has a graceful flair, which sparkles in the remarkable wit, imagination, and intelligence of these fast-paced tales.
