All aboard! This accordion-style book folds out car by car, taking readers on a tour of an airport train—inside and out. Readers are asked to help a girl bound for summer camp find her missing plane ticket, and as they search, they are introduced to all the passengers on the train. There are vacationing penguins, glamorous movie stars, traveling musicians, and other silly surprises sure to delight on every read. When readers flip the book over, they’ll discover a sweeping view of the airport—the control tower, runways, and parking lots—dotted with objects for readers to find and count. A fun, interactive ride from beginning to end!
