Princess Sylvie finds herself rushing to get to her place whenever a new Reader -- whether in Boston or Bangkok -- opens the book. Her mother, the queen, is especially frazzled when the popular story is loaded onto the Web, a weightless, "virtual" world of unforeseen challenges.

To cope with the stress, Sylvie convinces the Writer to add a new character, who gives yoga instruction to the storybook's cast in those moments when they have time off. But stress proves the least of their problems as strange things start happening -- words get changed around, scenes disappear -- and Sylvie and her friends must launch themselves into the labyrinth of cyberspace to confront a twenty-first-century evil that threatens to destroy their world.
