David Adler is back with a brand new chapter book series that will delight a new
generation of young readers
Danny Cohen’s new friend is 100% weird.
New to Danny’s fourth grade class, Calvin Waffle has a knack for following his classmates around to collect data for his science experiments. He carries jelly beans everywhere, and claims his father is a spy. Danny isn’t quite sure just what to make of this quirky newcomer until Calvin reluctantly agrees to help the baseball team. His ability to correctly predict each pitch before it’s thrown leads his team to victory and makes him a hero to his new friends.
David Adler, author of the popular Cam Jansen mystery series, creates another memorable character for his readers to befriend. Sure to be a publishing event.
