Back says: "Kate Bennett earned her M.D. at considerable cost - the breakup of her first marriage. Now she seems to have it all: a loving husband with a solid future, and an offer of promotion to chief of her pathology department at Boston Memorial. Then her world converges on her.
Powerful enemies at the hospital try to block her promotion. Her husband pressures her to place family before career. And Kate faces her biggest medical challenge: to discover the cause of the strange illness that has killed two women and is now endangering her close friend.
Determined to save her marriage, fighting to preserve her integrity - and ultimately her sanity - Kate continues her relentless probe into the mysterious deaths ... until she is risking not only her career and marriage but her very life. For Kate is up against a project that important people will stop at nothing to protect ... a terrifying medical discovery that has its roots in one of mankind's greatest evils."
