Grandpa's postcard said. "TOKYO IS WAITING." From the moment Wally and Emerson arrive, a runaway paper crane leads them through busy trains, glowing lanterns, and the winding streets of Tokyo. With help from a new friend and a surprising reunion from Wally's past, they discover that Grandpa's mystery is about more than finding the next clue. Along the way, Wally learns that patience, respect, and making room for others can help everyone move forward together. A new city. A new friendship. Another unforgettable journey.
