Hush

 "Few serial killers penned by suspense writers today are as warped or as fully realized as the Madonna Murderer, who preys on newborn baby boys and their unwed mothers. As if the crime itself isn't bad enough, the killer leaves a musical snow globe that plays "Hush, Little Baby" in the infant's crib as his calling card. It has been nearly two decades since Ivy Dunlap and her infant son were victimized by the Madonna Murderer. Unbeknownst to the killer, Ivy survived the assault. Her baby didn't. Now a respected criminal psychologist, Ivy is called into service by the Chicago P.D. when the killer resurfaces after 16 years of dormancy. Her personal interest in the case takes on a sharper edge when she learns that her partner, Detective Max Irving, has a son named Ethan who is the same age her child would have been had he survived. When Ivy tries to rattle the Madonna Murderer by publishing a "dead-baby letter" in the newspaper, the killer becomes more daring; he befriends Ethan, sends Ivy a chunk of his skin bearing a tattoo and expands his profile of victims. Although some readers may be turned off by the novel's graphic nature, a wealth of procedural detail, a heart-thumping finale and two scarred but indelible protagonists make this a first-rate debut." ~ Publishers Weekly
