About

I am an award-winning children’s book author, magazine writer, writing teacher and speaker. My wide-ranging passions include astronomy, volcanology, art, music, history, nature, waves, jokes, crayons, and mud — anything that catches my fancy. I believe in the power of discovery, untold stories, and persistent questions. Whether writing fiction or nonfiction for children or adults or teaching workshops, I hope my work opens doors, opens minds, opens possibilities.
