Munro, who knows her way around a maze, here fits a series of them into a simple storyline about a child who’s taking a trip to visit Grandmother, accompanied by Mom and Dad. Written in second person addressed to readers, the book starts at Sunnyside Airport, and from there, we move—never in a straight line!—through departures, check-in, security, airport shops and the food court, and terminals into a wonderfully roomy plane interior. At last, it’s time to take off: “UP, UP, AND AWAY!” Large, intricate, full-color spreads are rendered in Munro’s familiar style, not drawn with super-sharp outlines but nevertheless perfectly clear. In addition to the winding mazes, each double-page spread includes a challenging list of items to find, including (on each spread) “a copy of this book.” Direct instructions (“After Security, you enter the FOOD COURT and SHOPS. First get a cold drink”) guides readers through the mazes; an answer key keeps frustration at bay while providing useful and reassuring flying facts. The people depicted are diverse in terms of skin tone and ability; the protagonist never appears (the artwork is depicted from the youngster’s perspective). Whether preparing for a trip or whiling away hours on a flight, readers will find this book absorbing and informative.
