This is a pretty shameful admission, but I did read Rainbow Six some time ago in paperback, after I’d thought I had given up on Tom Clancy’s books. (This is in the Jack Ryan continuity, but Jack doesn’t appear.) I don’t remember now why I picked it up, but I actually liked it, or at least parts of it. This is kind of two books: in one, a new international anti-terrorist team, Rainbow, responds to a number of hostage situations; in the other, frothing environmentalists plot to kill off all of humanity (except them). No, really.
I liked the hostage rescue stuff; it scratches the same itch as his good stuff. However, the frothing environmentalist sections are unspeakably bad, and I skipped right past them on this re-read. It’s still a sizable novel even with the awful parts excised, so it served fine as bedtime reading. It is highly unlikely that I’ll try any other Clancy books, though.
