About the author

Dori Marx grew up in Austria and traveled the world several times before choosing New England as her home. There, she lives with her husband and three children, along with an ever-growing number of rescue dogs, goats, chickens, and pet ducks. Although she isn’t a veterinarian, she has a soft spot for all living beings and has even learned to coexist with the spiders in her barn.
Dori's books are illustrated by artists living in the countries that the Wonder World Kids visit. These local illustrators lend their unique style to the artwork for each book.
Wonder World Kids is her first chapter book series for emerging young readers. So far she has taken her young readers to the capital of Austria, the mountains of Peru, Central Park in New York City, the largest National Park in Kenya, and the oldest National Park in the United States, Yellowstone.
Dori is available for book presentations, readings, and signings at your school or library. Her Wonder World Kids books can be used to highlight a variety of topics, including conservation, environmental issues, geography, and various animal species. She offers grade level worksheets for K through 4 for each of her books.

In my books, I balance scientific information and observations with a touch of mystery and magic. In an effort to support local culture and entrepreneurship, my books are illustrated by artists living in the countries that the kids visit."
