What is The Iron Vow Society: The Complete Omnibus about?
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.
Includes Study in Scarlett, Tithe of the Sovereign, Ashes of the Vow, and What the Nothing Holds.
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.
World and setting
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.
What’s at stake
Across four novels, Scarlett challenges an inherited system that treats people as sources of magic and seeks a future on her own terms.
