Maternal infanticide, or the murder of a child in its first year of life by its mother, elicits sorrow, anger, horror, and outrage. But the perpetrator is often a victim, too. The editor of this revealing work asks us to reach beyond rage, stretch the limits of compassion, and enter the minds of mothers who kill their babies-with the hope that advancing the knowledge base and stimulating inquiry in this neglected area of maternal-infant research will save young lives.
