Mac was named the 2025-26 National Ambassador for Young People’s Literature by the Library of Congress (opens in a new window), the ninth book creator to receive this honor.
Mac grew up in California, and graduated from Pomona College where he studied literature under the writer David Foster Wallace. He was always “obsessed” with books and knew he wanted to be a writer, but didn’t figure out what kind until he worked at a kids’ camp in Berkeley one summer. Mac would make up stories for the kids and gained a reputation as the man with the fantastical tales. In a 2014 TED Talk, Mac said, “My job is that I lie to children, but they’re honest lies.” Mac was particularly influenced by The Stinky Cheese Man and Other Fairly Stupid Tales by Jon Scieszka and Lane Smith and Goodnight Moon by Margaret Wise Brown.
After college, Mac worked at 826 Valencia, a non-profit tutoring center that helps kids with with their writing and homework (founded by author Dave Eggars). He later became the executive director of the SoCal branch, 826LA, where he established the Echo Park Time Travel Mart, a convenience store for time travelers.
The Picture Book Manifesto (opens in a new window), written by Mac and signed by 21 other picture book creators declares that “A picture book should be fresh, honest, piquant, and beautiful.”

Like the life of Margaret Wise Brown, this is not a typical biography of an author. “Margaret Wise Brown lived for 42 years. This book is 42 pages long.” And while nobody’s entire life can fit in 42 pages, the important things can. In a conversational narration, key elements of Brown’s life and contributions are highlighted, illustrated in gently line and soft colors. Altogether, this is a fitting tribute to a singular author.
The Important Thing About Margaret Wise Brown

What does the skunk want? It’s not clear ― but soon the man has bought a new house in a new neighborhood to escape the little creature’s attention, only to find himself missing something …
The Skunk

It’s prankster against prankster in an epic war of trickery, until the two finally decide to join forces and pull off the biggest prank ever seen. (Goodreads)
The Terrible Two

Triangle — a triangular shape with big eyes and stick legs — decides to leave his triangular house to play a trick on square. But turnabout is fair play in this whimsical but sardonic tale. The illustrator’s signature style are textured, deceivingly simple, and placed on open pages.
Triangle
