Louise Cooper was born in Hertfordshire in 1952. She began writing stories when she was at school to entertain her friends. She hated school so much, in fact—spending most lessons clandestinely writing stories—that she persuaded her parents to let her abandon her education at the age of fifteen and has never regretted it.

She continued to write and her first full-length novel was published when she was only twenty years old. She moved to London in 1975 and worked in publishing before becoming a full-time writer in 1977. Since then she has become a prolific writer of fantasy, renowned for her bestselling Time Master trilogy. She has published more than eighty fantasy and supernatural novels, both for adults and children. She also wrote occasional short stories for anthologies, and has co-written a comedy play that was produced for her local school.

Louise Cooper lived in Cornwall with her husband, Cas Sandall, and their black cat, Simba. She gained a great deal of writing inspiration from the coast and scenery, and her other interests included music, folklore, cooking, gardening and messing about on the beach. Just to make sure she keeps busy, she was also treasurer of her local Lifeboat station.

Louise passed away suddenly from a brain aneurysm on Tuesday, October 20, 2009. She was a wonderful and talented lady and will be greatly missed.
