A heavy snowstorm traps the students and staff in the school overnight thanks to the snoozing Principal Slugmeyer who fails to send everyone home early. Trapped without beds, supper or pajamas, the children rely on their beloved Ms. Mudwortz to help them. And, of course, she saves the day with style, turning a potential disaster into a memorable sleepover that every school child dreams about (and every teacher fears). Originally published in 1991, this is one of Bianchi's best-selling books. With sales of 175,000 copies, it is now back in print as a Pokeweed Press title.
