Stephen Brunt's Gretzky's Tears: Hockey, Canada, and the Day Everything Changed may be the most anticipated hockey book of 2009.
Brunt was talking books with Bob McCown on Toronto's Fan 590 sports radio show Prime Time Sports. He does not go into the Gretzky's Tears book too much, but listening to the two of them talk about sports books was a real treat.
Here's the podcast link, with the opening 15 or so minutes being of interest here.
One correction for McCown and Brunt: Late in the conversation they ask whether a fiction sports book could ever be a top seller in Canada, and they dismiss that notion. Actually, I believe the best selling sports book in Canadian history is a fictional story: Roch Carrier's The Hockey Sweater.
