When Leo discovers a strange spiral key hidden in a crack in the sidewalk, he unlocks a doorway to a city where everything is backwards—cats walk people, trees stroll down the street, and tides roll through the cobblestones. But the Backward City doesn’t give up its secrets easily. With a flying house, a mysterious warning, and a choice that could close the door forever, Leo must decide what to do with the key before the City decides for him. A whimsical, imaginative adventure for young readers who love strange worlds and unexpected friends.
