It will be about the Mohammed cartoons, and, yes, the "controversial" cartoons will also be depicted. From CNN:

The cartoons of the Prophet Mohammed that sparked protests worldwide four years ago will be republished in a new book soon.

Staffers at Danish newspaper Jyllands-Posten said the cartoons will be in a book created by cultural editor Flemming Rose and will be titled "The Tyranny of Silence."

Rose could not be reached for comment.

The book is scheduled to hit stores on September 30, staffers said.
