At bedtime, a young boy who cannot find his favorite book imagines the various creatures that might have taken it from him.

    But what if somebody’s taste in pets runs to the more mechanical kind? What about those who like cogs and gears more than feathers and fur? People who prefer the call of a train whistle to the squeal of a guinea pig? Or maybe dream of a smudge of soot on their cheek, not slobber? In this spectacularly illustrated picture book, kids who love locomotives (and what kid doesn’t?) will discover where trains live, what they like to eat, and the best train tricks around—everything it takes to lay the tracks for a long and happy friendship. All aboard!
