Alexandra Sellers became interested in exotic locations when she was 10 and read The Arabian Nights. The book inspired her to begin writing, and she penned her first story, a fictionalized account of the life of her cat from the cat's perspective, soon after. When she reached adulthood, Sellers wrote a romantic short story and a science fiction novel. The short story sold immediately, but the science fiction novel was rejected by the first publisher who received it. Sellers took this as a sign to concentrate on the romance genre.
Her first romantic novel was published in 1980, and Sellers became a full-time writer. Many of her novels are set in exotic locations, some of them fictional countries. Romantic Times has described her novels as "enchanting...superbly integrating a memorable plot, delightful characters, and tender emotion."
In 1997, her novel A Nice Girl Like You was nominated by Romantic Times for a Reviewer's Choice Award for Best Silhouette Yours Truly. Three years later she received the Romantic Times Career Achievement Award for Series Romantic Fantasy.
Sellers has studied eight foreign languages. She attended the School of Oriental and African Studies in London, becoming the first student to be awarded a double degree in Persian and Religious Studies.
