Born into a middle-class family in South Africa, he is the youngest of three, having two older sisters. His father was an English chartered accountant, and his mother was a bank clerk. He enjoyed an idyllic childhood until his mother's death, after which he left Africa to reside in the UK. He attended boarding schools until he was 18, where he enjoyed adventure groups and sports. His work blends science, philosophy, and spirituality into rich speculative fiction. With a scientific background and a fascination for consciousness and metaphysics, Ashton creates worlds where scientific and spiritual forces converge. His writing challenges readers to question the boundaries between logic and faith, matter and mind.
