About Nathan
Nathan Christopher believes laughter is one of life's greatest gifts (ranked somewhere below unconditional love and a notch above cold pizza).
As a former child and aspiring adult, he knows firsthand what makes people of all ages laugh. Bad news: that's not his day job, where he's an MBA-wielding leader of engineering teams. But when the meetings (finally) adjourn, he happily trades spreadsheets for stanzas.
Books
Nathan is the author of When Santa Wrote Back! (Sourcebooks Wonderland, 2025), the first in his Who Wrote Back series of humorous holiday picture books. Two more titles in the series are forthcoming: When the Witch Wrote Back! (July 28, 2026) and When the Easter Bunny Wrote Back! (December 1, 2026), with additional unannounced titles in the works. You can browse his full catalog on the Books page, or find him on Amazon and Goodreads.
Beyond the page
As an engineering tinkerer with a penchant for innovation, Nathan has spearheaded an online clothing business and developed independent iPhone apps that garnered nearly a million downloads. That technical ingenuity extends into the kidlit world, where he is the creator of resources used by thousands of his fellow creators, including the PB Workshop online community, BookCrewHQ, and the PB Author Tools Google Docs extension.
Where he writes
Nathan writes in the attic of his century-old home in Windsor, Ontario—just across the river from Detroit—sharing life's ups and downs with his wife and ever-active children, who ensure endless material and a conveniently sleepless schedule for writing.
