This week, we're joined by local Christopher Clarey, who will be talking about his book about tennis great Roger Federer, "The Master," at the upcoming Newburyport Literary Festival. Hear about how he decided to write the book, what it's like covering sports in the age of social media, what Roger Federer is really like ("the most interesting thing about him is that he's interested"), and what he thinks about "King Richard," having such an up-close view of the Williams sisters and their father. Along the way, we talk about other great sports books ("Barbarian Days"!) and how you organize a book that could have been 1,000 pages long.
