Item from From Blood and Ash by Jennifer L. Armentrout
The substance at the center of everything — Atlantian blood heals, Poppy's blood resurrects, and the Ascended were created by corrupting it.
Deity blood is the currency of power in this world. In its pure form — flowing through Atlantian veins — it heals wounds and extends life. When Poppy's divine heritage awakens, her blood can do far more: resurrect the dead, fuel Primal magic, and remake the living. The Ascended were created by draining Atlantians of their blood and feeding it to mortals in a corrupted ritual, creating immortal parasites who must continue feeding to survive. Every war, every betrayal, every Rite in this story comes back to blood — who has it, who wants it, and what it can do.
