After centuries of war against orcs, elves, and vampires, humanity stands on the brink of extinction. Only three kingdoms remain, united under the fragile Crowns of Izaan. Opposing them is the alliance of the Grand Order: the orcish Kharmin Covenant, the disciplined elven Kingdom of Virmellia, and the vampiric Sombhrae Dominion that binds them.

Victoria Pembroke, an entitled daughter of wealth and reputation from Chicago, was killed by a mysterious person. Reborn in Izaan as Prae Anuraksa, she is the youngest daughter of a fallen lord in the ruined village of Song-Kawa. Stripped of privilege but not of ambition, she learned quickly that power demanded sacrifice. Prae would become the reason humanity endured — though never without cost.
