In Extremis

When several unsolved murders come to light in North America's safest city, no one suspects they may be connected. Certainly not Sharyn Barington, who has problems closer to home: A pious, domineering husband, a wayward son, a marriage devoid of passion, stretched to the limit at work and her self-confidence at rock bottom. She tries masking her anxiety with horoscopes and alcohol, but then unwisely stumbles into an affair with her son's best friend.
Blinded by guilt, she is slow to realize that someone close to her has a much darker secret of his own. It's a tale of blood, temptation, betrayal and redemption.
