Matt Richtel has been a reporter at the New York Times since 2000. He won the 2010 Pulitzer Prize for National Reporting for a series that exposed the pervasive risks of distracted driving and its root causes, prompting widespread reform. He is the author of A Deadly Wandering, which the New York Times Book Review declared, "deserves a spot next to Fast Food Nation and To Kill a Mockingbird in America's high school curriculum"; it was named a "best book of the year" by the San Francisco Chronicle, Christian Science Monitor, Kirkus Reviews, and Winnipeg Free Press. He has appeared on NPR's Fresh Air, PBS Newshour, and other major media outlets. He lives in San Francisco, California.

Lee Wildish lives in Lancashire and has been illustrating from a very young age.

He loves illustrating children's books and thinks there's nothing better than seeing people laughing at a book he's illustrated.

His titles include The Spooky Spooky House which was the winner of the Red House Children's Book Award 2013, and the New York Times bestselling How to Babysit a Grandpa.
