Definitely don't remember the last time I read this, been so long already, but I wanted something to read that was new but familiar. Well, it's obviously not really new to me, but since it's been years since the last reread, it practically is now, but still very familiar since I love this episode and have seen it plenty of times. The book is almost an exact replica of the episode, just filling in a little here and there, particularly with more of the events done by the original Enterprise crew. So no nasty surprises or changes - just the DS9 crew trying to save Kirk while dogging tribbles. :)
