An author’s first book is a special event, at least for the author, and even more so when it gains national recognition. That’s the happy situation for Shawn Wen, a former employee of RIPR. Wen has written an unconventional biography of Marcel Marceau, the acclaimed mime artist who died in 2007. The book is called A Twenty Minute Silence Followed by Applause. Wen was in Providence recently to give a reading, and said it was a homecoming, of sorts.
