The FAQ says "Lily first"

Maybe this has already been straightened out (I haven't caught up on
posting--sorry), but the thread about James being killed before Lily
is driving me crazy. The error may have been made on the Text-only
site and then corrected, or it may have been made by the original
poster. In any case, the FAQ on Rowling's official site
http://www.jkrowling.com/ clearly states that Lily comes out of the
wand before James because she was killed after he was.

In other words, this debate shouldn't even be occurring because 1) the
FAQ is right, and 2) the error by the American editor has been
corrected in recent reprints of the book. Please check out her
official site if you still think that "James first" is correct.

Thanks,
Carol
