Joystick lives in Joy House, that big sprawling definition on pages 635 and 636 in the dictionary. When a new word—J/psi particle—moves in next door, Joystick is eager to make friends and introduce himself. But as Joystick learns, J/psi particles are fundamentally unstable, and his new friend doesn't have long to live. Can Joystick muster the powers of his other friends' definitions to find a way to forestall J/psi's death?
