Lund started her writing career as a freelancer, contributing articles and stories to Reader's Digest, Ladies Home Journal and Good Housekeeping. She published eight popular children's books, including "Attic in the Wind," which sold over 1 million copies.
When her son Eric died of leukemia, Lund wrote a nonfiction book about his battle with the disease. "Eric" was published in 1974, and was eventually printed in 20 languages. Two years later, CBS aired a Hallmark TV movie based on her book, starring Patricia Neil, Claude Akins and Mark Hamill.
"I knew I was watching something unusually courageous. Being a writer, you take things in and regurgitate them automatically. I knew I was privileged," Lund once said.
