You need nodereference and nodereference_url modules.
You partially answered your own question. With the nodereference module in D6 (or just references in D7), you can create a link in the same place 'add a comment' appears (the . Links div) which says "add a review".
This link is because "reviews" has a field called something like "book reference" which is a noderef field. This review will automatically fill in the field with the book where the user clicked the link and, depending on how you set the field up, send you back to the referenced node (book) or the new review.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
