Service book for the Liturgy of the Presanctified Gifts, with an introduction by Fr Thomas Hopko.
Simple but perfect
I love these little books. They not only have the text of the service, but they have the music for the antiphons and reflections from Fr. Paul Lazor and and Fr. Tom Hopko. They slip easy into a cassock pocket or a purse so that you can follow along with your parish choir.
