"Pauline Dunn" was the pen name used by sisters Dawn Pauline Hartzell Dunn and Susan Hartzell. They wrote three books under this pseudonym before getting in legal trouble for plagiarizing sections of Dean Koontz's "Phantoms" in their books "The Crawling Dark" and "Demonic Color".

Dawn Dunn continued writing after the scandal, publishing under her own name a number of short stories in different genres. Her last published works were released in 2001. She currently works as a Nurse Practitioner in her home state of Indiana.
