'Forty Nights' is a volume of services for individual or communal use modeled after the Liturgy of the Hours and deeply sensitive to the connection between the earth environment and human prayer. All of the night prayer services are thematically developed. They bring together psalms, Christian prayers and hymns, and writings of mystics and naturalists, with liberal borrowings from many religious traditions. Daniel J. McGill is director of religious education and youth ministry at St. Joseph's Church in Grand Junction, Colorado. His other books include 'Becoming a New Testament Leader: Biblical Reflections for Training Youth Ministry Leaders' (2002).
