New Book Deal: One Cosmic Rock

I’m thrilled to be co-creating One Cosmic Rock: The Asteroid That Changed Our World with illustrator Julia Vasileva! A companion book to One Tiny Bubble: The Story of Our Last Universal Common Ancestor, this new picture book tells the story of the asteroid responsible for the dinosaurs’ extinction 66 million years ago. It also celebrates the resilience of life on Earth and the evolution of the diverse life-forms thriving today. It’s coming in Spring 2026 from Owlkids Books, with many thanks to my agent Ginger Knowlton of Curtis Brown for negotiating the deal!

    Fantastic! Did I tell you that we’re including copies of One Tiny Bubble in a set of palaeontology teaching kits I’m helping to develop? We may need to add copies of One Cosmic Rock as well…

    Congratulations!!
