Friendship with Jesus: Pope Benedict XVI Speaks to Children on Their First Holy Communion
Friendship With Jesus: Pope Benedict XVI Talks to Children on Their First Holy Communion is based on a dialogue in St. Peter's Square that took place in 2006
Artist Ann Engelhart thought the dialogue would make a wonderful children's book and asked me to help edit it and get it published. It was first published in England by the Catholic Truth Society in 2010 and then picked up by Ignatius Press in 2011.
