Baby Jesus Is Missing

Ambassador International

Early in December, Nativity figures begin disappearing across Reedy River. When a $500 reward is offered for catching the thief, Catherine and Susanna Mae decide to investigate. What begins as a Christmas mystery soon becomes a test of their judgment.

“One mark of a good children’s book is that it delights adults as well. I found Baby Jesus Is Missing to be such a book. Author Michael LaPenna introduces us to sisters Catherine and Susanna Mae as they solve the local town crime of the stolen baby Jesus figurines while also introducing us to the slang of the criminal and detective world in hilarious jaunts of language. The girls soon discover that one’s vocation, even crime solving, requires faith, virtue, and sacrifice. This is a fun faith-filled teaching story, full of surprises, and part of a book series that helps us all find the Baby Jesus and keep him in our lives.”

Angelina Grace

Ambassador International

One autumn afternoon, Catherine meets Ulga, a young woman living alone in a secluded hollow outside town. As the sisters get to know her, they begin to wonder about her circumstances and what they can do to help her stay safe.

“Michael LaPenna has given us a charming mystery story that unfolds the deeper mysteries about growing up, caring for others and learning to forgive and be reconciled. Join Susanna Mae and her sister Catherine as they solve the mystery of the strange girl in the woods and the stranger men who are searching for her. Written with clear simplicity, LaPenna has a gift for story telling that will attract and absorb the attention of young readers.”
