I liked that Sarisvati created the nature spirit and the ghosts (that's what I took away from it), and that there was sort of a sequel teaser... "will Pramesh defeat Sarisvati? Stay tuned!"... but the story felt too fast and too disjointed... like... in some stories, there's the "round-up" -- Star Trek V is a good example of this. They collect all the characters from wherever they are, show what they've been doing, then everyone goes on a mission together. This was the round-up. But there wasn't much of a payoff, and that's what bugged me.
Also, Edgar wasn't really a sympathetic character -- I was more interested in Raven, honestly -- and I felt that, at the end, it was pretty lame that Edgar and Raven ended up boinking on the airplane while Pramesh (the true "geek" of the bunch) was exiled to AIville.
After the greatness that was Impossible Dreams, I felt quite let down by this story. As others have said, great ideas, but not the best execution in the universe.
