Welcome to my website. I hope you enjoy your visit as much as I enjoy writing books for young readers from preschool through young adults. My forty-two books include biographies of famous people like Albert Einstein and some people you may not immediately recognize like Philo Farnsworth. (He invented electronic television and came up with the crucial insight at age fourteen!)  Most recently I have written about the global refugee crisis and climate change for young adult readers. 

I’d be happy to hear from you with any questions or comments about my books. I love to hear from teachers, parents, and young readers.
