Andrea Beaty is the author of the bestselling Questioneers series, among other children’s titles. She lives just outside Chicago.

David Roberts has illustrated many children’s books, including the bestselling Questioneers series. He lives in London.

"This ingenious spin-off of Beaty and Roberts’s Rosie Revere, Engineer aims to get children asking questions, finding treasure where others see trash, and dreaming up solutions for such real-world “problems” as figuring out how to open a door with one’s elbow...  Games, profiles of inventors, and an all-around focus on pie-in-the-sky thinking add up to an activity book with substantial depth."
