Milo wants a story, but his mom is too busy to entertain him. Instead, she encourages him to go out and play in the snow. At first, Milo is disappointed - he doesn't want to play outside, he wants a story. But when he starts to follow a trail of mouse-prints, he discovers signs of activity all around, prompting him to ask, "What happened here?" Before long, he's using his imagination -- depicted in lush wordless spreads that capture the vividness of Milo's fantasies -- to fill in the gaps. By the time Milo comes home, he's the one with stories to tell.
