Friends of the Library Book Sale at the Sudan Temple

At the Book Sale this weekend, I bought a book which I thought was already at home on my bookshelf.  I wanted a spare, because it was an important book to me.  When I got home, I couldn't find my book, and since this is a very unusual type of book and looks exactly like the one that I thought I had on my bookshelf at home, I can only guess that this is my book, that I lost it, and somehow found it here again.  This was a very strange feeling....
