Gareth L. Powell is a British author known for using intimate, character-driven science fiction to explore themes of identity, loss, and the human condition.

He started writing as a student in the early 1990s and was fortunate to count Diana Wynne Jones and Helen Dunmore as early mentors. After completing his education, he spent many years working in software marketing while continuing to write in his spare time.

Powell’s first professional publication came in 2005, with the story ‘The Last Reef,’ which appeared in the long-running British SF magazine Interzone. His first short story collection and first novel followed in 2008 and 2010 respectively. Both were well-received by critics and readers alike, establishing him as a promising new voice in science fiction.

To date, Powell has written ten published novels, two short story collections, three novellas and a nonfiction writing guide, and has been described by Adrian Tchaikovsky as, “One of the masters of the genre.”

His work has repeatedly featured on the Locus magazine bestseller list and been recognised with several awards. He has twice won the coveted British Science Fiction Association Award for Best Novel, and has become one of the most-shortlisted authors in the 50-year history of the awards.

He has also been twice shortlisted for the Locus Award, as well as being a finalist for the British Fantasy Society Award, the Seiun Award in Japan, and the Canopus Award for Excellence in Interstellar Writing. His novels have been translated into numerous languages and he has gained a dedicated following of readers around the world.

Powell is married to the American author J. Dianne Dotson and they have four children between them. He is represented in all professional matters by Alexander Cochran of the C&W literary agency.
