It's not that she dies, is that she doesn't come back and Geralt commit suicide by monsters.
That's actually the ending I got when I played the game the first time (I personally though I was trying to be supportive of Ciri) and I'm still wondering if it tainted my view of game or not (i.e. I think the game is greatly overrated).
You were the Dad that gave Ciri the plastic bag to play with when she was 3.
I wouldn't come back, either.
