The Lion & the Deathless Dark Summary: A Tale of False Gods and Fierce Vengeance
In a world where the sun was murdered and vampires rule the dark, one woman’s grief becomes a weapon that could shatter the divine order.
The Lion and the Deathless Dark by Carissa Broadbent is the first book in the Bloodborn Duet and the fifth installment in the Crowns of Nyaxia series.
TL;DR: The Quick Snapshot
Kyrene is no hero.
She is a bounty hunter wearing a stolen identity, wielding a sword meant for someone else.
When the gods she pretended to serve let everyone she loved die, she does the unthinkable: she kills her own patron goddess.
That single act of spite draws the attention of Septimus, a vampire prince cursed by his bloodline. He sees in Kyrene a weapon capable of killing the gods who have tormented humanity for millennia.
What begins as a transaction becomes something far more dangerous—for both of them.
- Premise: A false chosen hero and a cursed vampire prince form an alliance to assassinate the gods of a dark, sunless world.
- Main Characters: Kyrene—a cynical bounty hunter posing as a divine warrior—and Septimus—a calculated Bloodborn prince racing against his own biological curse.
- Core Conflict: Kyrene and Septimus hunt and kill members of the White Pantheon, only to discover they are pawns in a much older scheme orchestrated by Acaeja, the Goddess of Fate.
- Ending: The mission to kill Nyaxia fails. Acaeja seizes control of reality itself. Septimus loses his mind to the Bloodborn curse, and Kyrene is Turned into a vampire to survive. She awakens three months later in a world being dismantled and rebuilt, vowing to hunt Acaeja and find Septimus.
- Themes: Grief as fuel for destruction, the lie of divine justice, monstrous recognition between two damaged people, and a woman’s refusal to be a passive victim of fate.
- Genre: Dark romantasy with epic fantasy scale, set in the Crowns of Nyaxia universe but accessible as a new entry point.

The Lion and the Deathless Dark Summary: The Full Story (Spoilers)
Warning: This section contains complete spoilers, including the ending.
The story unfolds in Obitraes, a realm that has not seen sunlight in ten years. When the sun god Atroxus was murdered and the sun itself shattered, vampire Houses swept in and claimed dominion over human lands. Humanity now exists as cattle, servants, or desperate survivors scraping by in the ruins.
Kyrene is one such survivor. She carries Zefiah, the Blade of Retribution, and presents herself to the world as the Vindica Ultis—a holy warrior of Shiket, the Goddess of Justice.
The truth is far uglier. Ten years ago, during the chaos of the vampire invasion, Kyrene murdered the real chosen hero with a rock. She stole the sword to survive a miscarriage and the collapse of civilization.
Her carefully constructed lie begins to crumble when a vampire attack on the stronghold of Hegaella kills her only companions: Valentina, a teenage machinist she viewed as a daughter; Mirie, a priestess who believed in Kyrene’s hidden goodness; and Marko, a mercenary who died protecting Valentina.
Their deaths break something inside Kyrene. In a rage, she calls upon Shiket—and when the goddess arrives valuing vengeance over protection, Kyrene kills her.
This impossible act draws the attention of Septimus, a prince of the cursed House of Blood. He recovers Kyrene and reveals that seers have long prophesied her role in collapsing the White Pantheon. He proposes an alliance: together, they will systematically eliminate the gods.
Their hunt begins with Ix, Goddess of Sex, and Kajmar, God of Pleasure. In the northern territories, Kyrene and Septimus infiltrate a divine stronghold through dangerous games of seduction, drugs, and hallucination. The visceral slaying of these two gods reveals the Pantheon’s capacity for betrayal and the depth of Kyrene’s own buried desires.
As they travel, the relationship between hunter and prince deepens. Both are monsters by circumstance—Kyrene by survival, Septimus by birth.
Septimus eventually confesses his true goal: he wants to kill Nyaxia, the Mother of Vampires, to free his people from a biological curse that eventually turns every Bloodborn vampire into a mindless, feral beast.
Their journey leads to Vaktrana, the Bloodborn capital, where the full tragedy of Septimus’s family and his curse becomes undeniable.
The two share a night of profound vulnerability before the Nightborn army besieges the city. They flee through hidden gates, racing toward the ruined temple in Hegaella where Shiket’s remaining blades are kept.
At the temple, they are ambushed by Srana, the Goddess of Machinery. She has reanimated the corpses of Valentina, Mirie, and Marko as metal-infused automatons. Kyrene is forced to face the twisted remains of everyone she loved. She kills Srana in a fit of grief and spite.
The final confrontation with Nyaxia goes wrong. Kyrene’s attempt to kill the Mother of Vampires fails because she is not the true chosen one the prophecy required. Nyaxia reveals she has manipulated the Bloodborn bloodline for millennia.
Then Acaeja, Goddess of Fate, reveals herself as the true architect of everything. For two thousand years, she has orchestrated the god-war to eliminate her siblings and Nyaxia. Her goal: to become the sole ruler of a dismantled and rebuilt world. Nyaxia is banished to the deadlands.
Septimus succumbs to his curse and loses his sanity. In their final moments of lucidity together, he honors Kyrene’s request and Turns her into a vampire to save her from a slow, fatal wound.
The book ends three months later. Kyrene awakens as a newborn vampire in a world being unraveled by Acaeja. People hang suspended in light as the goddess methodically rebuilds reality to her design.
Kyrene’s first coherent thought is a vow: she will hunt Acaeja and find Septimus, no matter what remains of him.
