The latest Account occurs between books 1 and 2.  If you haven't finished book 1, PLEASE, FOR YOUR OWN SAFETY (and enjoyment of the first book), DON'T READ THIS.  It will ruin surprises that await you at the end of book 1.  And really, there are only so many chances for true surprise in life, and one of them is in books.  So don't let yourself be tempted.  Seriously.  Just get out of here and go finish the book.  Trust me.
