I don't remember seen in this here but I just saw these posts on LinkedIn form SANS instructor Jonathan Ham:
I guess it's official. Shon Harris' work helping IT workers achieve their CISSP certification will continue in her very unfortunate absence, with a revision to her best-selling volume to be provided by yours truly. McGraw-Hill has asked me to carry on what she began, and it's my honor to do so.
I should have been more clear: I'll be taking on the Practice Exams volume into the 3rd Edition. Another author has agreed to take up the All-in-One Exam Guide
Definitely great news to see these picked up.
