Mark Dagostino is a New York Times–bestselling coauthor and former senior writer for People magazine. As a journalist, he was on the scene when JFK Jr.’s plane went down, reported from Ground Zero in the aftermath of 9/11, and stood witness to the Miracle on the Hudson. He also cut his teeth in the courtroom, learning valuable lessons from the Pamela Smart case in his home state of New Hampshire, covering Rosie O’Donnell’s $100-million lawsuit with publisher Gruner+Jahr, and more. Along the way, he quietly became one of the most respected celebrity journalists in the business. Today, he’s back in his home state, where he lives a somewhat quieter life with his two children.
