Susan Finden was born in 1954 and is a mother of three children who lives and works as a part-time health care worker in Plymouth in Devon, England.

Watson-Brown, an animal lover herself who had previously ghostwritten The Pet Whisperer by Sarah-Jane le Blanc, said that Finden's book "is such a positive and uplifting story, and it's all told in Sue's voice.
