I've made this suggestion before but I'd like to see if anyone else has any ideas. Keep in mind we need two actors to play Lena--one when she was quite young and the other as a ravaged, mad adult.
"O let my name be in the Book of Love!
It be there, I care not of the other great book Above.
Strike it out! Or, write it in anew. But
Let my name be in the Book of Love!" --Omar Khayam
