Zoe defeating the Cybermen's fleet is just awesome. :-) I think this is the story we first meet Benton in, too, isn't it?

Btw, I see you're enjoying the Jamie-Zoe-Doctor dynamic (it's wonderful, isn't it?) - have you ever read LilacFree's Transit of Venus? It's a lovely look at them, probably the ultimate non-sexual OT3 fic. (Though it does refer to The War Games at the end, so depending on what you know about that, you might want to save it till you reach the end of that.)
