Candlewick Press, 2014. Picture book.
From the author-illustrator that brought us the Caldecott Honor Journey comes another breathtaking wordless masterpiece. The quest begins when two friends at a city park encounter a king, who comes unexpectedly out of a door underneath a bridge. The king quickly hands the friends a map before he is dragged back into the door by medieval looking guards. The friends use their chalk to draw keys to enter the door. Using the map as their guide, they collect more chalk by drawing solutions to the challenges they encounter and eventually save the king. This book beautifully portrays the power of combining problem solving and creativity. I expect this to be a Caldecott contender.
