I'm an adventure gamer, and have played Jane's Gabriel Knight games. Her storytelling is legendary. Thanks for mentioning this and reminding me. I meant to get this book.
She has written several books, including a novelization of the first two Gabriel Knight-games.
Oh, and you have played Grey Matter, of course?
Anyway, I finished Dante's Equation (brilliant all the way through) and started
Somewhere south of midnight by Stephen Laws. It's pretty good so far, although I've only finished part 1. (about fifty pages.)
Edit: Getting a bit off-topic here, sorry. But a quick check on wikipedia (I know...) came up with this:
"After the release of
Blood of the Sacred, Blood of the Damned, Jane Jensen stated that she had started planning a possible story and setting for a fourth game. A search of the SIDNEY computer interface for "gk4" in
Blood of the Sacred, Blood of the Damned brings up an entry on ghosts, which Jane Jensen has remarked would have been the antagonists in her outline for a fourth entry to the series.
However, no
Gabriel Knight 4 has been announced. In August 2006 it was confirmed that Jane Jensen's next adventure game project would not be a new
Gabriel Knight but the revival of
Gray Matter, a game which was released in German speaking territories in November 2010 , and is set for release internationally in February 2011."
So there wasn't a Gabriel Knight 4 because she wanted to work on Grey Matter instead, but she did plan a story for it, and now that Grey Matter is finished... dare we hope?
