These charming readers, which are appropriate for a second grade reading level, contain "stories written and compiled in days long past by Catholic nuns in America and dedicated to Mary the Mother of God our dear Lady of the Miraculous Medal." My second grader (who is somewhat advanced in reading level) enjoyed these very much and polished off all four volumes in the first week of school - including one book which she read straight through without putting it down (she requested that I include that detail in the review).
