This is another terrific novel of suspense by Lisa Scottoline. Christine & Marcus Nilsson discover that Marcus cannot produce viable sperm - crushing their dreams of having a baby of their own. They make the difficult decision to use a sperm donation to enable them to become parents. When Christine finally conceives, she sees a TV clip of a man arrested for the brutal serial murders of three nurses. She is convinced he is the donor, judging from his background and the picture provided by the sperm bank (the sperm bank won't reveal the identity of the donor because of privacy regulations).
Marcus fears the donor is a psychopath and their unborn child will inherit the same tendency to kill. He wants Christine to have an abortion. Their different opinions on this cause great friction in their marriage. What follows is Christine's quest to meet the donor and find out if he really is the killer and the donor.
Great read with an ending that I was happy with!
