A boy learns that nature is full of stories to tell when he finds and follows a mouse's tracks in a wintery wood. 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. A must have for the winter season, Liza Woodruff's Once Upon a Winter Day is a fun read-aloud that shares details about animal behavior from a child's perspective.
