The Light of Western Stars by Zane Grey

Three days after her return to the ranch Madeline could not discover any physical discomfort as a reminder of her adventurous experiences. This surprised her, but not nearly so much as the fact that after a few weeks she found she scarcely remembered the adventures at all. If it had not been for the quiet and persistent guardianship of her cowboys she might almost have forgotten Don Carlos and the raiders. Madeline was assured of the splendid physical fitness to which this ranch life had developed her, and that she was assimilating something of the Western disregard of danger. A hard ride, an accident, a day in the sun and dust, an adventure with outlaws -- these might once have been matters of large import, but now for Madeline they were in order with all the rest of her changed life.

There was never a day that something interesting was not brought to her notice. Stillwell, who had ceaselessly reproached himself for riding away the morning Madeline was captured, grew more like an anxious parent than a faithful superintendent. He was never at ease regarding her unless he was near the ranch or had left Stewart there, or else Nels and Nick Steele. Naturally, he trusted more to Stewart than to any one else.
