I'm currently reading Moloka'i, by Alan Brennert
Anger and doubt erupted again like lava, emotions entirely inappropriate for this place, this act. She sprang to her feet and bolted from the chapel, startling a sister about to enter, and retreated to the safety of her room. There she fell again to her knees, knitting her hands together in a tortured mimicry of prayer. Whenever she felt the anger bubbling up she would stop, take a few minutes to compose herself, then start again; but though the anger slowly cooled she found that oozing up between the words of contrition and adoration was a troubling fear. Fear of herself and what she was capable of, what she had done to that little girl; and fear that perhaps Sister victor was right, that contagion was all around them.
Just have to add, I am LOVING this book. Loving. More later.
