Mark was born in Ann Arbor, Michigan, and raised in France. He graduated from Brown and lives in New York.
Mark is the author and illustrator of several award-winning picture books and graphic novels, including Seadogs, Long Night Moon, To Dance, Moving House, and Sailor Twain, which author John Irving called “a gripping novel with compelling characters, enhanced by haunting, erotically charged artwork.” Mark’s latest project is the collaborative graphic novel 5 Worlds, an epic science-fiction series for young readers. The New York Times Book Review hails it as “ . . . a bang-zoom start to a series that promises to be epic in both the classical and internet senses of the word. . . this is a capital-S Saga.”
Mark is also the founder, and Creative and Editorial Director of First Second Books, Macmillan’s graphic novel house. First Second offers an ambitious collection in every age category, in a wide range of themes and styles, with talent from all over the world. First Second has garnered an unmatched array of literary awards, starred reviews and bestsellers—including for the original works of National Book Award Finalist and Printz Winner Gene Luen Yang, and beloved bestselling titles such as This One Summer, Real Friends, Spill Zone, and many more. Mark has appeared before thousands of librarians and educators to speak about the graphic novel renaissance.
Mark has given lectures and workshops internationally and all around North America, for authors, artists, librarians, students, executives in many venues, at tradeshows, companies, Comic Cons, and animation studios, including Blue Sky, Dreamworks, Disney, and Pixar, for both creative and executives.
