Donald Cowper is a writer and entrepreneur who helps run a boutique marketing consultancy. Before writing In Silent Worlds, a speculative thriller with commercial crossover appeal, he made a career as a nonfiction storyteller. His works include five coauthored narrative non-fiction books, most of them focused on entrepreneurship. Two of those books, Mega-Selling and The 8 Best Practices of High-Performing Salespeople, have been translated into multiple languages, the latter becoming the number 1 business book in Canada. His book for freelancers, Breaking the Time Barrier, saw over 130,000 downloads in its first 90 days after release, and was praised by best-selling authors Tim Ferriss (The 4-hour Workweek), Michael Gerber (The E-Myth) and Daniel Pink (Drive). He also wrote a popular column for Inc.com featuring the wild risks of notable entrepreneurs.

As a kid he was an actor for two seasons of the acclaimed SCTV, starring alongside his uncle John Candy. His ten-year-old face is featured on T-shirts and mugs as the kid who was scared to death by Joe Flaherty’s story about rats storming a lighthouse.

He lives in Canada with his partner Emily Ohanjanians, a professional editor and author of The Book Tour, releasing in the spring of 2026 with Penguin Random House.
