Just Take My Heart by Mary Higgins Clarke
Clark's stunning new novel takes her into unchartered new territory, as Emily, one of three inseparable friends since childhood, learns that Natalie is on life support after a terrible accident. She begs the doctors to allow the third friend, Alice - near death herself - to be the recipient of her heart. But what Emily does not realise is that Natalie's death was no accident, and that she has unknowingly set in motion a series of shocking and dangeorus revelations that will put her own life at risk. Probing as deeply into the human mind as she does into the human heart, Mary Higgins Clark has written a novel of rare suspense and deep emotional terror.
