Wayne Gretzky book on hockey history coming this fall For Wayne Gretzky, there’s something special about the number 99. The NHL’s all-time scoring champion has a deal with G.P. Putnam’s Sons for a book about the game’s history and his own place in it. Putnam told The Associated Press that the book, currently untitled, will be published this fall, coinciding with the league’s 99th anniversary. In a statement released Thursday through his publisher, Gretzky said he would provide his “take on some of the great moments” in hockey and tell stories previously known only to “friends, family and teammates.” Gretzky’s No. 99 was retired by the NHL after his final season in 1999, when he was also inducted into the Hockey Hall of Fame. For his upcoming book, Gretzky will collaborate with bestselling hockey writer Kirstie McLellan Day.
