My latest “big machine” obsession: HELICOPTERS. 🚁 I simply cannot describe how AMAZING they are: The incredible engineering that allows them to do what they do, their ability, the unbelievable skill of the pilots… I’m awestruck — and counting the hours until I get the chance to go up again. 💫 THIS is what has inspired me to write my next picture book series, “Roto and Roy Helicopter Heroes.” I hope fans of my bestselling truck and train books will check it out. I’m eager to hear your thoughts!
