Not a fan of "Bridge on the captain"?God, it's been years since I read both those books. I don't remember much about Crossover but Probe was a pretty good book I thought, with an interesting backstory about the probe. It has a, how shall we put it, interesting authorship history which can be found numerous places online. But it's still a pretty good book.
Oh, and the book for Generations does a pretty good job fixing some of the weaknesses I found in the movie--well except for Kirk's final death, there's only so much one can do with that.

I enjoyed Probe as well. I want to know more about these "Super Klingons" that killed off the whale creatures.
