LOGISTICS. Like the nuts-and-bolts, training-montage kind of stuff. I have this pile of stories that I just kind of coo over, because they make Auror trainees take procedure course/the accountants think they're padding the bills, but a team of Slayers really does eat that much/etc.

I also enjoy those things! Plus, well-written kinkfic, poly, kidfic, and completely over-the-top h/c.
