When I first read this book I was so shaken I couldn't have written a review. I held onto the book for years, knowing I'd have to read it again just to be sure I hadn't gone crazy while reading it the first time. Finally I had enough distance from it (I thought!) to read it a second time...but the impact was just as powerful. You've read those books, seen those movies wherein you find yourself thinking about an action a main character is taking and wanting to say 'You fool! What are you thinking of?' or the like, right? Well, Harrison does such a good job of reeling one into the story your thoughts are more likely going to be "I know why we're doing this, but I wish we didn't have to". Gives a new meaning to the word 'gripping'.
