Arielle is the daughter of noted author Sterling North, who wrote Rascal. She is also the niece of author, poet and editor Jessica Nelson North. She is one of the copyright owners of Sterling North's body of work. She now has 3 children and 7 grandchildren, and is a resident of St. Louis, Missouri.

Arielle is from a multi-generation literary family. Arielle's great-grandparents, James Hervey Nelson and Sarah Orelup Nelson, were Wisconsin pioneers. In 1917, which would have been her great-grandfather James Hervey Nelson's 100th birthday, three of her great-uncles, including early Amazon missionary Justus Henry Nelson, wrote extended biographies about their parents and their pioneer farm life. These writing efforts may have been a literary inspiration to both her father Sterling and her aunt Jessica.

Arielle has written:

• Hurry Home Grandma
• Noah's Cats and the Devil's Fire
• The Lighthouse Keeper's Daughter

She has edited:

• Ask the Bones: Scary Stories from Around the World

She also reviewed children's books for the St. Louis Post Dispatch for 26 years.

Her biography is captured in:

• Contemporary Authors

Arielle is an honorary director of the Sterling North Society in Edgerton, Wisconsin. She also donated some of Sterling's mementos to the Sterling North museum there.
