Still, here's my Fic of the Week choice - Office Work is a six part fic by imortalitybites from way back in October 2007. It's primarily Jack/Ianto, but mentions Gwen/Owen. Rated PG-13 for sexual themes.
Summary: There's not much work getting done at Torchwood today.
Part 1 Part 2 Part 3 Part 4 Part 5 Part 6
That's it then. Happy reading everyone.
