Harry is excited! Today is the first day at his new job at the Four Color Balloon Factory. Harry loves balloons almost more than anything! When Mr. Huffy, his new boss, tells him to blow up 100 balloons for Mrs. Doopido's birthday party, Harry can't wait to get started. But when Harry wants to make sure he has the correct number of balloons for the birthday party, counting the balloons gets confusing. And no matter what he does, the number still comes out wrong. What is the best way to count to 100? Colorful illustrations and a clever storyline will help young readers figure out what Harry needs to do to solve his math dilemma. A former music and English teacher, Wendy Ulmer was inspired to write Zero, Zilch, Nada because of her own "math phobia" and struggles with math as a child. She also wrote A Isn't for Fox: An Isn't Alphabet. Wendy lives in Arrowsic, Maine. Laura Knorr is also the illustrator of the popular holiday title, The Legend of Papa Noël. Zero, Zilch, Nada is her second book with Wendy Ulmer and her fifth book with Sleeping Bear Press. Laura lives in Commerce, Georgia.

Laura Knorr was born and raised in northeastern Pennsylvania and remarks, “I may have left that delightful state but it is home in my heart wherever I may go.”

She graduated with a Bachelor’s of Fine Arts in Illustration from Ringling School of Art and Design in Sarasota, Florida, and has worked as a freelance illustrator for a handful of years. Laura lives in Commerce, GA.
