Mr S A First Day of School Boo

Prepare for plenty of giggles as a kindergarten class arrives for their first day of school but can't find their teacher—only a delicious-looking sandwich and the words "Mr. S" scribbled on the chalkboard. Chaos ensues as the kids argue whether the sandwich must be their teacher. A comical first-day-of-school book of mayhem and chaos by Monica Arnaldo, perfect for fans of Miss Nelson Is Missing.

“This might be the funniest first-day-of-school book I’ve ever read." —Adam Rex, New York Times bestselling author of School’s First Day of School

It was the first day of school.

But even the kindergarteners of room 2B could tell something was seriously wrong. . . . Where was the teacher? Who left this sandwich on the desk?

The only clue, written on the chalkboard, were three simple letters: Mr. S

Praise for Mr. S:

Monica Arnaldo was born in Ontario, Canada, where the trash cans are often filled with raccoons and half-eaten cheeseburgers (but seldom any glowing seeds). When she wasn’t drawing or reading, she spent much of her childhood pondering some of life’s great questions, such as “Can I pet that wild animal?” and “Why not?” She has since written and illustrated several picture books and moved to Quebec, where raccoons speak French.
