Barbara Underwood was born and raised in Sydney, Australia; the only child of German migrants who provided a rich and diverse childhood environment. Already in third grade she wrote a short children's book for a class project and realized that she was deeply satisfied with creating stories. In sixth grade, for another class project, her teacher was so impressed by the lengthy story she submitted, that he commented at the end "I see we are going to have another author".

Over the years Barbara kept writing one thing or another, but only as a hobby while she pursued other interests and goals. In the 1990s, she completed a correspondence course in professional writing, doing it in her spare time after work. This led to having a few short stories published, but what she really wanted to do was write a proper novel.

At this time, Barbara had travelled extensively and gained a wealth of knowledge and experience in subjects that held special appeal for her, namely ancient history, myths and legends (such as Atlantis, the builders of megaliths around the world), folklore (the belief that a god-like race gave mankind its technology), human psychology and the culture of other countries. What better subject for her first novel than to combine all these elements into one big adventure!
