Plainville author Jeff Kinney will release the seventh installment of his “Diary of a Wimpy Kid’’ series on Nov. 13 through Amulet Books, an imprint of ABRAMS. The book will be released all over the world the very next day. Kinney was at the Bologna Children’s Book Fair on Wednesday to announce the big news, and he was nice enough to call us Wednesday evening - at about 11 p.m. Italy time. Kinney said this is his first time at the Italian book fair, and that he took the trip to get a sense of his international success. “What I’ve found is that it’s a great way to see a bird’s-eye view of the series,’’ he said, adding that he’d be flying back to his family in Massachusetts on Thursday. Kinney wouldn’t reveal much about the new “Diary,’’ but his publisher did give us this image as a teaser. Looks romantic.
