The Fae & Alchemy series by Callie Hart continues to captivate with Brimstone, the second installment following the explosive events of Quicksilver. Where the first book introduced us to a world where ancient magic collides with forbidden romance, this sequel plunges deeper into the complexities of power, sacrifice, and the weight of unwanted crowns. Hart crafts a narrative that refuses to offer easy answers, instead presenting a heroine caught between worlds and a love that transcends the boundaries of realm and species.
A Queen Who Never Wanted the Throne
Saeris Fane finds herself in an impossible position at the opening of Brimstone. Crowned queen of the Blood Court after her transition into a half-vampire, half-Fae hybrid, she grapples with a role she never sought and powers she barely understands. Hart’s portrayal of Saeris’s internal struggle rings authentic throughout the narrative. The young woman who once survived the brutal streets of Zilvaren through cunning and determination now faces political machinations that make street survival seem simple by comparison.
The author excels at depicting Saeris’s reluctance to embrace her new status. She doesn’t transform into a confident ruler overnight, nor does she suddenly develop diplomatic skills. Instead, she remains fundamentally herself—pragmatic, fierce, and occasionally reckless. When she delegates authority to Taladaius rather than pretending competence she doesn’t possess, it demonstrates a self-awareness that makes her compelling as a protagonist. Her relationship with power becomes one of the novel’s central tensions, particularly as she discovers that queenship comes with both political responsibilities and magical ones she cannot ignore.
The God-Bound Connection
The mate bond between Saeris and Kingfisher deepens considerably in this installment, moving beyond the initial intensity of their connection in Quicksilver. Hart writes their relationship with a raw emotional honesty that avoids the pitfalls of many fantasy romances. Fisher’s unwavering devotion never diminishes Saeris’s agency, and their telepathic connection serves the story rather than simply providing convenient communication.
Their separation for much of the narrative—with Fisher traveling to Zilvaren alongside Carrion Swift to retrieve Hayden and gather silver—creates genuine tension. The brief moments when they reunite crackle with need and relief, but Hart wisely avoids allowing the romance to overshadow the larger plot. Fisher’s journey through Zilvaren reveals new dimensions to his character, particularly his capacity for patience and his growing acceptance of allies he once would have dismissed.
Carrion Swift: From Smuggler to Reluctant Hero
Carrion Swift emerges as one of Brimstone’s most fascinating characters. His transformation from roguish smuggler to someone bearing the weight of his true heritage creates some of the book’s most emotionally resonant moments. The scenes in Zilvaren, particularly surrounding Gracia Swift’s funeral, demonstrate Hart’s ability to weave profound grief into an action-driven narrative. Carrion’s humor serves as armor against pain that runs centuries deep, and his journey toward accepting his Fae identity parallels Saeris’s own struggle with her hybrid nature.
The dynamic between Carrion and Fisher evolves from antagonistic to something approaching genuine partnership. Their banter provides necessary levity during the darkest moments, yet Hart never allows their developing friendship to feel forced. The reveal of Carrion’s connection to the Yvelian throne adds layers of political complexity that promise to complicate future installments.
Alchemical Magic and Its Terrible Price
Hart expands the magic system introduced in Quicksilver with impressive detail. The exploration of Alchemical runes, particularly the appearance of the brimstone rune alongside Saeris’s quicksilver mark, suggests powers that operate on fundamental levels of reality. The author wisely avoids explaining everything at once, allowing the magic to retain its sense of mystery and danger.
The concept of the quicksilver as a sentient force with its own desires and motivations adds philosophical depth to what could have been a simple power source. Saeris’s interactions with the quicksilver—her attempts to partner with it rather than dominate it—speak to broader themes about control versus cooperation. The revelation that stargazer birds were actually pages from an ancient Alchemical text exemplifies Hart’s creative worldbuilding.
The Shadow of Zilvaren
The Silver City remains a haunting presence throughout Brimstone. Hart’s depiction of Madra’s propaganda machine, turning Saeris into both martyr and villain, demonstrates sophisticated understanding of how tyrannical regimes manipulate information. The journey through Zilvaren’s segregated wards reveals a city designed to oppress, where even the architecture reinforces hierarchies of power and privilege.
The revelation that certain residents of Zilvaren, including Elroy, have always known about the Fae and the quicksilver suggests secrets that run deeper than previously imagined. These mysteries promise to become increasingly relevant as the series progresses. The infected feeders originating from Zilvaren create an immediate crisis that connects the two realms in dangerous ways.
Supporting Characters Who Demand Attention
The ensemble cast continues to impress in Brimstone by Callie Hart. Foley’s reintroduction as a vampire struggling with his transformation adds tragic weight to the story. His isolation in Ammontraíeth’s library tower, his attempts to deny his hunger, and his eventual acceptance of friendship demonstrate character development that feels earned rather than convenient. His relationship with Fisher and Lorreth carries the complicated history of shared trauma.
Taladaius evolves from mysterious vampire lord to something more nuanced. His request to sever the maker-made bond with Saeris speaks to his genuine care for both her and Fisher. The theatrical disavowal ceremony and his subsequent role as Saeris’s advisor position him as an unexpected ally. Hayden Fane’s introduction adds family dynamics that complicate Saeris’s choices, though his initial naivety occasionally frustrates.
Hart’s Signature Style
Callie Hart’s prose maintains the dark elegance that characterized Quicksilver. She writes action sequences with visceral immediacy—the scorpion demon attack pulses with nightmare logic, while the defense of Inishtar against infected feeders becomes a desperate ballet of violence. Her descriptions balance beauty and brutality, finding poetry in devastation.
The author’s willingness to let her characters suffer, to deny them easy victories, elevates the narrative tension considerably. When Saeris cannot simply blast her way through every obstacle, when Fisher must endure separation from his mate, when Carrion loses the last of his family line—these moments of powerlessness make their eventual triumphs meaningful.
Where Brimstone Stumbles
Despite its considerable strengths, Brimstone by Callie Hart occasionally suffers from pacing issues. The middle section, while necessary for character development and world expansion, sometimes feels protracted. Certain revelations from Edina’s mysterious book arrive with less impact than intended, partly because the restrictions on when Saeris can read specific passages create artificial obstacles.
The proliferation of new threats—infected feeders, political machinations in Ammontraíeth, mysteries in Zilvaren, prophetic warnings—sometimes overwhelms the narrative. While Hart generally manages these multiple plot threads with skill, readers might occasionally feel pulled in too many directions simultaneously. Some secondary characters, particularly the warriors at Cahlish, remain somewhat underdeveloped despite their importance to the larger story.
Themes That Resonate
At its core, Brimstone by Callie Hart explores the burden of power and the cost of leadership. Saeris never wanted to be queen, yet circumstances thrust the role upon her. Her attempts to delegate, to acknowledge her limitations while still protecting those under her care, speak to mature leadership that fantasy literature rarely examines. The novel asks whether one must accept roles they never chose simply because they’re capable of filling them.
The theme of transformation—both physical and emotional—pervades the narrative. Saeris’s transition into a hybrid creature mirrors her psychological evolution. Carrion’s acceptance of his Fae heritage, Foley’s struggle with vampirism, even Fisher’s gradual opening to new alliances—each character must reconcile who they were with who they’re becoming.
Setting Up Future Conflicts
Brimstone by Callie Hart concludes while clearly establishing stakes for the series’ continuation. The quicksilver’s increasing activity, the political instability in multiple realms, Madra’s machinations in Zilvaren, and the mysterious warnings about darkness to come all promise escalating conflicts. The revelation about Onyx’s resurrection through Alchemical magic suggests costs that have yet to be fully paid.
Hart wisely avoids wrapping up every plot thread while still providing satisfying resolution to the book’s immediate conflicts. Readers finish Brimstone with answers to questions raised while gaining new mysteries to ponder before the unnamed third book arrives.
