Wonderstruck (2011) is an American young-adult fiction novel written and illustrated by Brian Selznick, who also created The Invention of Hugo Cabret (2007). In Wonderstruck, Selznick continued the narrative approach of his last book, using both words and illustrations — though in this book he separates the illustrations and the writings into their own story and weaves them together at the end.
