By now you guys know of course that the 4th KGI book, Whispers at Dark, featured the youngest Kelly brother, Nathan, and that Echoes at Dawn, the 5th book in the series, will feature Rio, one of the team leaders and will release July 2012.
So here is the official announcement for the 6th book in the series, Shades of Gray, which will release in Jan 2013 :)
Shades of Gray will feature Cole and P.J. two of the KGI team members who you’ve met in the first 4 books and will of course see again in the 5th book as well.
Obviously the series will (hopefully) be longer than six books since obviously there are more of the brothers (Donovan and Joe) to write about but I have plans for some of the team members as well :) (Just in case anyone thought that I would only be writing stories for the six Kelly brothers)
