Katie took a small intake of breath and held it.  Her body had gone frozen, her face pale, and her mind blank.  She felt dizzy, and blinked several times as though trying to wake her self up.  Her head nodded lightly as though on auto-pilot and she swallowed, trying to moisten her mouth that had suddenly gone very dry.  The change in her demeanor was obvious.  She had changed from a confident young woman into a very frightened little girl.
