From Brendan Connell, who tells you that the poster says, "Create Security."
(Maybe I'll use this and make up some alternate covers that you can put over the book. I quite like the cover for Black Sheep, but you have to admit, this is appalling, and perfect.)
(EDIT: Actually, Brendan is quoting the Italian poster. This one means For More Security. Yes, I know what I'm doing here.)
