It's a blog! Mainly of book reviews.
If you liked Lock In you will probably like this. If you like murder mysteries and aren't opposed to SF you'll probably like this. If you liked anything else Scalzi has written you'll probably like this. And if you like witness protection cats, you will definitely like this!
It doesn't repeat the whole subtext of Lock In and doesn't really replace that subtext with anything, but it tells an amusing tale of smart-arsery, corruption, murder, arson, wanton destruction of telefactors - and a cat called Donut.
You're gonna hafta read the book to find out what happens to him.
