Twelve-year-old Toulouse "Tull" Trotter lives on his grandfather's vast Bel-Air parkland estate with his mother, the beautiful, drug-addicted Katrina—a landscape artist who specializes in topiary labyrinths. He spends most of his time with young cousins Lucy, "the girl detective," and Edward, a prodigy undaunted by the disfiguring effects of Apert Syndrome. One day, an impulsive revelation by Lucy sets in motion a chain of events that changes Tull—and the Trotter family—forever.

In this latter-day Thousand and One Nights, a boy seeks his lost father and a woman finds her long-lost love . . . while a family of unimaginable wealth learns that its fate is bound up with two fugitives: Amaryllis, a street orphan who aspires to be a saint, and her protector, a homeless schizophrenic, clad in Victorian rags, who is accused of a horrifying crime.
