Booking Through Thursday - Rewrite

My friend Busy has been doing these for awhile, and I found this question rather interesting:

If you could rewrite the ending of any book, which book would it be? And how would you change it?

SPOILERS! (Obviously.)

Unfortunately, I don't have a great answer.  My first thought was of Rhett Butler's People - the novel of Gone with the Wind from Rhett's point of view.  The author, Donald McCaig, wrote past the original ending of GWTW and reunited our star-crossed lovers.  And then he burned down Tara.  I found that totally unnecessary and called him names.

Another thing I would change is all of the classic novels where the heroine had to die in order to spare or reclaim her honor.  Anna Karenina and The House of Mirth come to mind.

I had the fleeting thought that Dallas Winston really didn't have to die at the end of The Outsiders.  But he sort of did.  However,  I refuse to believe that Sirius Black had to die at the end of Harry Potter V!

Seems to be all about the character deaths with me.
