Yes, In EXTREMIS (like the other CSI/Las Vegas books by Max Collins) is based on the actual TV series characters (Gil, Catherine, Warrick, Sara, et al) and the CSI/Las Vegas 'stage sets'; but the story itself is new and not based on any aired episode. In essence, I came up with new episode/story in which all of the characters work a pair possibly-related crime scenes (just like on the TV espiodes); but it will be printed in a book format instead of acted and broadcast. The trick was to make certain that I got the 'voices' of the each of the characters correct as they've been developed and evolved by the scriptwriters.
And yes, after realizing that GSRs did not stand for gunshot residues [I hadn't watched all of the episodes of the first six seasons before starting in on In EXTREMIS ... my turn to be embarrassed], I sat down, carefully watched the emotional interactions of Gil and Sara in the episodes of the last two seasons, and then gave them one more opportunity to be emotionally involved with each other. But, being a thriller writer, I decided to enhance their emotions by putting them in extreme danger at the same time. If you happen to read the story, please let me know if you think I got the 'voice and tone' of their emotions correct.
BTW, if IN EXTREMIS is ever converted into a film script (highly unlikely), CBS would probably have to use a lot of stunt doubles in the filming. I didn't treat your beloved characters all that gently in the story.
