"My book is about a man named Alexander Mackenzie and a journey he took in 1789. He was looking for the Northwest Passage and what he actually found was the Arctic Ocean. Alexander Mackenzie has been lost a bit to history, at least in the United States, and I started writing this book when I discovered that Mackenzie was the first European to cross North America, or the first recorded crossing of North America."
