I never read just one book. I have multiple books on the go at once in multiple locations. So …
In the chapel:
Common Worship: Daily Prayer and NRSV Bible. (This is not technologically true. I use a version of Common Worship that I have adjusted to my needs, but the outline is there.) I also use several different prayer books for other devotions.
In the dayroom (that is, the inner cell):
This Is Epistemology: An Introduction by J. Adam Carter and Clayton Littlejohn.
Also:
Rasputin: Faith, Power, and the Twilight of the Romanovs by Douglas Smith
Also:
The Word in the Desert: Scripture and the Quest for Holiness in Early Christian Monasticism by Douglas Burton-Christie
In the parlour (main room where people can visit):
The Nature of Biblical Criticism by John Barton
Also:
The Word in the Desert: Anglican and Roman catholic Reactions to Liturgical Reform by Barry Spurr
Also (and, to be honest, I like to have this book on hand to “soothe my soul”):
Anglican Papalism: A History: 1900-1960 by Michael Yelton
I am also reading a novel:
The Vinyl Detective: Written in Dead Wax by Andrew Cartmel
On my Kindle (that travels with me):
Introducing Medieval Biblical Interpretation: The Senses of Scripture in Premodern Exegesis by Ian Christopher Levy
Now that was real fun! I love talking about books.
