Ryan North's recent work includes the nonfiction books How To Take Over The World and How To Invent Everything, the semi-fictional graphic novel adaptation of Kurt Vonnegut's Slaughterhouse-Five, and the so-far-fictional Unbeatable Squirrel Girl series for Marvel. He's a multiple New York Times bestseller whose work has been translated into 16 different languages to date, and as a linguist, he's very happy about that. He lives in Toronto, where he once messed up walking his dog so badly it made the news.
