About 2 years, I reviewed the first edition of the CISSP Study Guide. 

Just out is the CISSP Study Guide, Second Edition of the bookby Eric Conrad, Seth Misenar and Joshua Feldman.  And yes, they are all CISSP certified.

The overall framework and content of the guide is the same.  The update covers the new information in the (ISC)² CBK (Common Body of Knowledge) that underwent  a major update in January 2012.

Like the first edition, the book includes two online practice exams that serve as supplementary study material for study guide.

The second edition like the first, is made those who have a decent background in information security, and don’t need a five-pound tome to lug around. For those people, the CISSP Study Guide, Second Edition is a quality reference guide that can assist them in studying for the exam.
