This is an ebook-only short, barely a novella. It's also vintage Scalzi, funny and irreverent and insightful.

A senior staffer for an unnamed president gradually comes to the shocking realization that the president's brain is missing. He's walking, he's talking, he's functioning normally--but his brain is missing! (Yes, insert jokes here; Scalzi is careful to ensure you can't peg this president as being either Bush or Obama. He's not doing contemporary political commentary, here.)

The senior staffer starts digging for an answer to what's happened, and solution to the problem. But is it a problem? Who is responsible? Does this need to be fixed? And what's going to happen to the nosy staffer?

It's wickedly funny, and well worth the time you'll spend reading it. Recommended.
