Issue #37 of Albedo One contains a story by Gareth Stack - his first published story in fact. This takes the total numner of SF authors called Gareth to 4, as far as I am aware.
- Gareth D Jones
- Gareth Owens
- Gareth L Powell
- Gareth Stack
Of course there may be more. Drop me a line if you're an SF author called Gareth.
Surprisingly there aren't that many authors called Jones, considering it's a pretty common surname.
