My review of Sr. Joan Chittister's excellent look at the Liturgical Year is up at Theolog. Although Sr. Joan is Catholic, and her take is based on that form of the calendar, Protestants following the Revised Common Lectionary, will find much that is useful here.
To give you a hint, here is a paragraph from the review:
The Liturgical Year is part of the Phyllis Tickle-edited Ancient Practices Series on aspects of the spiritual life such as the Eucharist, common prayer, fasting and the Sabbath. In this book, Chittister urges us to attend to the liturgical calendar; if we don't, she says, the secular/civil one will dominate. The liturgical calendar is more than a set of guidelines for preaching and decorating the sanctuary: it is an invitation to center our daily lives in the birth, life, death and resurrection of Jesus.
