This was a really good re-imagining of the Winchester family, if they had lived in the world of Starship Troopers. But it's less than 2k, so all there's really time for is a teeny tiny glimpse of a very interesting world.

It's completely self-contained, but at the same time I can imagine it as the prologue to a BB-length fic that's just begging to be written.

Anyway, I highly recommend this one. Just know that it's super short.
