Sita Dulip has missed her flight out of Chicago. But instead of listening to garbled announcements in the airport, she discovers a method of bypassing the crowds at the desks, a nasty lunch, whimpering children, their punitive parents, and the blue plastic chairs bolted to the floor: she changes planes—literally. Sita discovers entire planes of existence and visits societies not found on Earth—bizarre societies that share similarities with Earth's cultures and sometimes open doors into the alien.
