Meet Dori - Author of
the Wonder World Kids series

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 dogs, goats, chickens, quail, and fish. Although she isn’t a vet, 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.

She is currently working on the fourth book in her popular Wonder World Kids Series.

 β€œI wanted to create books with shorter chapters and text blocks so you can keep reading. Let's be honest: isn't it always more fun to finish 5 chapters before bedtime?

 Go beyond fairies who lose charms or princesses on unicorns. In my first story you'll discover fun facts about royal horses, a child composer, and even a delicious chocolate cake... and best of all, they're all true!

I love working with local illustrators who capture the real atmosphere of the destinations in their pictures. Isn’t it exciting to see how Lilly, Fynn, and Celia’s style changes in each adventure?”
