Laurell K. Hamilton has been churning out a lot of short stories online in recent years. Some are actual short stories (crappy ones), and some are cut scenes from the books. But one thing will always be certain: you will be horribly overcharged.
On the other hand, Shutdown was a freebie released during the government shutdown... and I still feel horribly overcharged.
No, this story has absolutely nothing to do with any kind of shutdown. Or anything else in the Anita Blake universe. I can only assume it was free because LKH's publisher refused to let themselves be associated with it, because this story is just more Anita-is-awesome-poly-is-the-only-way-to-live masturbation.
