Casting Shadows

I'm reading a book, but I don't know if I was the one who wrote it or not. It's about this guy in Alaska who's writing to his daughter in an email. Every now and then the letter breaks off to show what's happening with his daughter. I distinctly remember reading about her being in an alley about to be killed. At the end the guy gets really mad because he never heard from her again--he doesn't know that she was killed.

[Clearly, my brain ripped this one from Family Guy.]
