Five authors have made the 2017 short list for the $10,000 John W. Dafoe Book Prize, which was revealed Wednesday.
The national book prize recognizes non-fiction about Canada and is named after the long-time editor of the Winnipeg Free Press.
Broadcaster and journalist Sandra Martin is in the running this year for her non-fiction book on assisted death.
A Good Death: Making the Most of Our Final Choices, published by HarperCollins, already won the $40,000 British Columbia National Award for Canadian Non-Fiction.
Other finalists for this year's Dafoe Book Prize include Robert Wright for Trudeaumania: The Rise to Power of Pierre Elliott Trudeau.
John Boyko made the cut for Cold Fire: Kennedy's Northern Front and Asa McKercher is a finalist with Camelot and Canada: Canadian-American Relations in the Kennedy Era.
The short list is rounded out by Adam Lajeunesse for Lock, Stock, and Icebergs: A History of Canada's Arctic Maritime Sovereignty.
The winner will be named later in the spring and get the award at a dinner in May.
