Another book to add to those listed by @mbloch is Reading Maimonides' Mishneh Torah by David Gillis
https://www.amazon.co.uk/Reading-Maimonides-Mishneh-Littman-Civilization/dp/1802070338
In this highly original study, David Gillis demonstrates that the
Mishneh Torah, Maimonides’ code of Jewish law, has the structure of a
microcosm. Through this symbolic form, Maimonides presents the law as
designed to perfect the individual and society by shaping them in the
image of the divinely created cosmic order. The commandments of the
law thereby bring human beings closer to fulfilling their ultimate
purpose, knowledge of God. This symbolism turns the Mishneh Torah into
an object of contemplation that itself communicates such knowledge. In
short, it is a work of art.
Gillis unpacks the metaphysical and cosmological underpinnings of
Maimonides’ scheme of organization with consummate skill, allowing the
reader to understand the Mishneh Torah’s artistic dimension and to
appreciate its power. Moreover, as he makes clear, uncovering this
dimension casts new light on one of the great cruxes of Maimonides
studies: the relationship of the Mishneh Torah to his philosophical
treatise The Guide of the Perplexed. A fundamental unity is revealed
between Maimonides the codifier and Maimonides the philosopher that
has not been fully appreciated hitherto.
Maimonides’ artistry in composition is repeatedly shown to serve his
aims in persuading us of the coherence and wisdom of the halakhic
system. Gillis’s fine exegesis sets in high relief the humane and
transcendental purposes and methods of halakhah as Maimonides
conceived of it, in an argument that is sure-footed and convincing.
