I would like to know what does "still" refers to exactly. I guess it has to do with movement. I have to translate this into Spanish and I don't know its particular meaning here: "I have a year", she had said, face still and certain as the grave, full of a cold fire that Kate had never seen before.
Could you tell me a synonym? Can it be similar to "blank face"? Or "serious"?
Thank you all in advance.
