"Mouse feels all alone one dark and dreary night. She wonders if anybody else feels lonely, too. She's not sure if a single person can make a difference, but she decides to try. Mouse lit one light... and the result is magical. One by one, others in the neighborhood follow Mouse's lead. With each new spark, the stormy night becomes less gloomy. This luminous picture book is a brilliant and tender call to action, encouraging readers to spread kindness and create change in the world--one light at a time"--
