The moving recollections of Rebecca Ruter Springer serve as emotional support to Christians who are bereaved and grieving, or contemplating the nature of the heavenly afterlife.

Arranged in chapters as a loose narrative, Intra Muros comprises of a series of dreamlike episodes and reflections upon the essence of life, death and what comes next after we perish. Steeped in the Christian tradition, the author's narration traverses the spiritual planes that follow death, and her descriptions of heaven are evocative and reassuring.

The appearance of the heavenly realms, the blessings of the angelic spirits, and the journey the believer's souls makes the author's words profound and vivid to read. The imagery that the writer presents is enormous in scope, yet the emotional comfort she seeks to provide remains constant - sight of the book's practical purpose, of comforting Christians who are bereaved through the harrowing experience of loss, is never lost.
