It has been said that the part of Medieval history which scholars find most challenging to elucidate is the emotional life of Medieval families. Indeed, it is an area that is surrounded by a sense of mystery and superstition. In The Rescue of the Innocents, Ronald Finucane seeks to examine this area by focusing on the influence of miracles on the lives of children during the Middle Ages.

Finucane explores rampant reports of "miraculous" happenings, delving into the experiences of six hundred children who were rescued, cured, or resuscitated - it was thought - by the holy dead. He analyzes the impact that these wonders had on the families of the children, comparing the differences between experiences of families in the north and the south of Europe. The reactions of mothers in particular, in comparison to fathers and other kin, are studied for their distinctive quality.

In addition, Finucane breaks with the traditions of Medieval historians and concentrates on only one type of source: hagiographical records.
