WOW! I got this book a few months ago because I had never been able to see the episode and I was very curious...what in the world IS the Caretaker anyway???? By the time I had finished reading, I was dying to see the episode. I finally found it (on this web site!) for sale and paid $45 for a ST set when I couldn't care less about the other three episodes included. I just had to get "Caretaker." Well... The episode is awesome. HOWEVER, when you go back and read the pages in the book again, you realize how much is missing!! I was almost disappointed in the episode (almost) after reading all the details in the book. I found myself waiting often for a great line that never came. (Examples: "If a member of my crew gets hurt because you make a mistake, you won't have to worry about an anklet, mister..." and "I'll go in first; I'm expendable"...among others.) So, I would recommend the book more for those who HAVE seen the episode. You'll be awestruck by all the details! But if you haven't seen the episode, be prepared to feel like some things are missing, once you've read the novel.
