Ken Dryden is publishing a book that advocates for better safety practices in hockey. Game Change highlights the risks and dangers of head injuries and tells the story of hockey player Steve Montador.

Montador was a defenseman who played in 571 games for six different teams over 10 seasons in the NHL. Montador died suddenly in 2015 at the age of 35.

After his death, Montador was diagnosed with chronic traumatic encephalopathy (CTE), a neurodegenerative disorder associated with repetitive head impacts. Symptoms may include memory loss, impaired judgment, depression and progressive dementia.

In Game Change, Dryden talks to former players like Rhett Warrener and Marc Savard, and consults with neurobiology experts. His publisher, Penguin Random House Canada, writes that Dryden also outlines a plan of action for fans, players, parents and NHL decision makers.

Dryden became a household name in the 1970s, winning six Stanley Cups as the goaltender for the Montreal Canadiens. He published his first book, Face-Off at the Summit, while still playing professionally. After retiring from sport, he entered politics and penned five more titles, covering a wide variety of subjects including hockey, education and Canadian identity.

His 1983 memoir, The Game, was a finalist for a Governor General's Literary Award and a Canada Reads contender in 2012. It is widely considered to be one of the greatest books about hockey ever written.

Game Change is slated for an October 2017 release. Dryden is also working on a book with coach Scotty Bowman, according to Quill and Quire, which will be published in fall 2018.
