Lena is a fingerprint expert at a crime lab in the small city of Syracuse, New York, where winters are cold and deep. Suddenly, a series of crib deaths--indistinguishable from SIDS except for the fevered testimony of one distraught mother with connections in high places--draws the attention of the police and the national media and raises the possibility of the inconceivable: could there be a serial infant murderer on the loose? Orphaned as a child, out of place as an adult, gifted with delicate and terrifying powers of intuition, Lena finds herself playing a critical role in the case. But then there is the mystery of her own childhood to solve. Could the improbable deaths of a half-dozen babies be somehow connected to her own improbable survival?
