Help me indie-pop fans (song ID)

I just heard this on a cable promo for the Dawn of the Dead remake, but Googling the lyrics didn't turn anything up and it's not on the soundtrack.

Female singer, kind of high-pitched, very clean production, the only lines used in the promo: "now I can see you, plain as can be/ your face in the shadows, smiling at me" (or maybe the commas should be line breaks)

If anyone knows the band/song, it would be most appreciated.
