Carissa Broadbent’s The Lion and the Deathless Dark is the fifth novel in the six-book Crowns of Nyaxia series. This fantasy universe comprises three interconnected duologies: Nightborn, Shadowborn, and Bloodborn. Each follows different protagonists within a world shaped by rival vampire Houses, a sprawling, apocalyptic war between humanity’s gods—the White Pantheon—and the vampire goddess Nyaxia’s plan to destroy humanity. While building on this cosmic struggle for power, The Lion and the Deathless Dark also functions as the first installment of the self-contained Bloodborn Duet, which centers on a new primary romance between the human divine warrior Kyrene and the vampire prince Septimus. This structure allows the novel to be accessible to new readers while still advancing the series’ main plot for established fans. Understanding this book’s dual role—as both a continuation of a series-long war and the beginning of a more intimate, character-focused duet—is key to appreciating its narrative scope. It balances the introduction of a new central relationship with the weight of an established world on the brink of collapse, leading to a two-part story that will resolve its own arcs while impacting the entire series.
The Lion and the Deathless Dark explores the impact of events in book three, The Songbird and the Heart of Stone, in which the protagonist, Mische, killed Atroxus, the sun god, to prevent the creation of a permanent sun that would destroy vampires. The sun god’s death plunged the world into lasting darkness, allowing vampires to move freely and leaving human territories more vulnerable. The Bloodborn Duet introduces Kyrene, a human warrior who has not appeared in earlier novels, and pairs her with Septimus, a vampire prince whose schemes have influenced previous conflicts, particularly in the Nightborn Duet. Septimus’s claim that he caused the sun’s fall and the worsening war reflects his indirect involvement in the wider chain of events.
Broadbent’s novel is an example of “romantasy,” a literary subgenre blending high-stakes, complex fantasy worldbuilding with the plot structures and character-driven focus of romance. The genre has experienced a cultural and commercial boom, largely propelled by the “BookTok” community on the social media platform TikTok. BookTok creators’ enthusiastic, short-form video reviews have the power to turn novels into bestsellers overnight, with romantasy being a particular favorite. According to Publishers Weekly, despite overall declining print sales, adult fantasy print sales rose 51.7% in 2023 (Milliot, Jim. “Print Book Sales Fell 2.6% In 2023.” Publishers Weekly, 5 Jan. 2024), an increase largely attributed to BookTok’s influence. Novels like Rebecca Yarros’s Fourth Wing became viral sensations through this grassroots marketing. The Lion and the Deathless Dark aligns with this audience's tastes, featuring a world of warring gods and hierarchical vampire houses—the “fantasy” element—while centering on the developing relationship between Kyrene and Septimus, which provides the romantic core. The novel’s combination of world-ending stakes and intensely personal connection exemplifies the hybrid genre that has come to dominate modern fantasy publishing.
Broadbent’s work builds upon two significant lineages within modern fantasy: the survival-focused tradition of young adult dystopian fiction and the politically complex world of adult vampire romance. The grim, post-apocalyptic setting of the Crowns of Nyaxia series, where the sun has been extinguished and humanity is prey to vampires, echoes the high-stakes, oppressive environments popularized by Suzanne Collins’s The Hunger Games. In that series, teenagers are forced to kill one another in a televised spectacle to maintain social order. Broadbent’s world shares this bleak ethos of survival at any cost; Kyrene’s worldview is a direct product of this environment, as shown when she states, “We don’t all get to survive. Every minute we go on living, it’s because someone else didn’t” (54).
This ruthless philosophy is layered with complex political machinations between warring supernatural factions, a hallmark of authors like Sarah J. Maas, whose A Court of Thorns and Roses series features complex and often antagonistic Fae courts vying for power. Similarly, The Lion and the Deathless Dark explores the fraught alliances and rivalries among the vampire Houses of Shadow, Blood, and Night. Septimus, a prince of the House of Blood, must navigate this treacherous landscape, where political maneuvering is as deadly as open combat. This blending of dystopian survivalism with courtly intrigue creates a world that is both physically and politically perilous for its characters.
