Twenty-five years ago, D. C. Martin had an idea for a book. But it wasn't until the pandemic that he finally sat down to start crafting the novel that quickly became Hindsight is 2020. Martin has always been interested in books and studied English literature at the University of Guelph. His love for the Toronto Maple Leafs, movies, music, video games, and popular culture is reflected in the book's many references. Martin's travels and parents (both published authors) have also been deep sources of inspiration for his writing.

D. C. Martin lives in Guelph, Ontario, with his wife, daughter, and cantankerous cat.
