Following Beantown’s bouncing balls

“The Die-Hard Sports Fan’s Guide to Boston’’ by Christopher Klein (Union Park, paperback, $17.95) is a handy primer for the sports-bewildered. It begins with a bucket list of 10 sporting events before focusing on the big four: baseball, football, basketball, and hockey. Klein, raised in New York until his family moved to Greater Boston when he was in the sixth grade, offers advice on scoring tickets, autographs, and a parking spot. Klein’s sports obsession extends to the Boston Demons Australian football team and the 45 local teams in the Gaelic Athletic Association.
