At once a lament-psalm and a love song, Grief's Liturgy records Gerald Postema's work and worship of grief upon the loss of his wife, a year's work aided by the companions--poetry and prayers, icons and images, music and silence--that sat patiently with him. Structured around the liturgy of the Divine Office, reflections in each "hour" take on a distinctive expressive and emotional tone and fall into a jagged, broken rhythm over the course of each "day" yielding ultimately an understanding of the life-affirming necessity of grief.
