Ridgefield — A new book in the South Ridge Elementary School library might have a list of authors that rivals its word count. “Eva Extraordinaire” is about the school’s mascot, and it was written as a collaborative effort between all 500-plus students spread across each grade in the school. Sixth-graders visited students in kindergarten through second grade to brainstorm ideas for the book’s plot, and the story was then passed up to older students to figure out where to take it next. Art students from each grade drew illustrations for “Eva Extraordinaire.” The project also used a variety of topics the students were covering in their respective classes. The book has a local feel, as much of the story takes place in the Ridgefield National Wildlife Refuge and numerous local businesses are referenced.
