Have only recently become aware of the phenomenon of
book trailers, which are exactly what they sound like - video commercials for books.
Just happened across this one for Tobias Buckell's "Sly Mongoose" (on my mind because I lamentably had to return his first novel, "Crystal Rain" to the library before I could finish it):
Nice soundtrack, but IMHO should have made more of the
space zombies vs. alien-tech ninjas angle.
