The Bloodwind is a novel written by Charles L. Grant. It was first published in 1982.
Pat Shavers was an artist and a teacher. She'd had a rough life: a divorce, and the loss of her child. But now things seemed to be in order. Except for the strange force riding in the saily movements of her life. A threat rising in the envy of her colleagues, the jealousies of her new lover, the hidden enmity of those who seemed to be her friends. It was a dangerous fury gathering itself against her. The wind rose and swirled, threatening to destroy her.
