About the Author

Sue Fliess is the author of over 40 children’s books, including Beatrice Bly’s Rules for Spies: The Missing Hamster, Goldilocks and The Three Engineers, Rumble and Roar, Sadie Sprocket Builds a Rocket, numerous Little Golden Books, and more. When she was young, she got caught spying on her older sister. It didn’t end well and likely turned her off of becoming a spy later. Which is probably good, as she is better at writing than spying. Sue lives in Northern Virginia with her family and two dogs, and loves to travel, write, and read. Visit her website at
