About Shivaree, Wikipedia sez, "In the American Midwest, along the Missouri River in Nebraska and Missouri, the term takes on the meaning of playfully kidnapping the bride, curiously similar to some Central Asian traditions."

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
