This book is clearly a labour of love written by an enthusiastic amateur. I found the information often vague and muddled, the photos sometimes hilariously bad, and the writing overly riddled with exclamation points.
If you're looking for a detailed and thoroughly researched history of the camp, I recommend Camp X: Canada's School for Secret Agents 1941-45 by David Stafford. It's on the dry side, but much more informative.
