What is Tithe of the Sovereign about?
Scarlett’s place inside the Marrow hardens into a contest over sovereignty, loyalty, and which part of herself the academy expects her to surrender.
The Iron Vow Society is K.S. Valentina’s complete four-book dark-academy fantasy romance series following Scarlett from the Sectors into the Obsidian Marrow, where founding families, living oaths, and dangerous men compete to decide who gets to shape the world beyond the academy.
People and creatures
Scarlett is a resourceful Null from the impoverished Sectors, apparently without magic in a world that prizes it. Her circle includes Draven, a Shadow-Wolf Alpha; Syth, an ancient naga living within the mountain; and Lysander Frostwoven, the frost-wielding Fae heir.

A secondary fantasy world where magic determines rank. The Obsidian Marrow academy sits inside a mountain, above older powers, with founding families and blood oaths controlling access to power.

Scarlett’s fight over sovereignty becomes a fight over who may extract power, impose loyalty, and decide what her body and magic are for.
