Quicksilver — Fae & Alchemy, Book One

A Thief Pulled Into the Fae

Callie Hart was already a prolific romance author when Quicksilver launched her into the romantasy stratosphere, and the book arrived in 2024 as one of the genre’s biggest word-of-mouth successes. Its heroine is Saeris Fane, a sharp-tongued thief scraping out survival in Zilvaren, a brutal, sun-scorched desert city where water is currency and mercy is scarce. When a heist goes wrong and Saeris touches a strange pool of liquid silver, she is wrenched through a portal into Yvelia — a frozen fae kingdom as cold as her homeland is hot — and into the middle of a war she does not understand.

It is a classic fish-out-of-water, dropped-into-another-world setup, and Hart uses it to maximum effect: Saeris’s outsider perspective lets the reader discover the fae realm alongside her, while her hard-won street instincts keep her from being a passive newcomer.

A Heroine Worth Following

Saeris is the book’s great strength. She is funny, prickly, and pragmatic — shaped by a life of deprivation into someone who trusts no one and survives on wit and nerve. Her first-person voice carries the novel: sarcastic without being exhausting, vulnerable beneath the armour, and quick enough to make even the slower stretches enjoyable. In a genre where heroines can blur together, Saeris has a personality sharp enough to remember.

Her value to the fae, it turns out, is alchemical: she has a rare gift for manipulating quicksilver, the magical metal at the heart of Yvelia’s war effort, which makes her a weapon both factions want to control. That premise gives her agency in the plot — she is not merely a love interest in a strange land but a genuinely consequential figure.

The Enemies-to-Lovers Engine

The romance pairs Saeris with Kingfisher, a battle-hardened, infuriating fae warrior whose antagonism toward her is the book’s central charge. Their dynamic is built on relentless banter, mutual irritation, and the slow, grudging erosion of hostility into something hotter — the enemies-to-lovers formula executed with energy and genuine chemistry. Quicksilver runs spicier than many of its peers; readers who want their romantasy to deliver heat as well as tension will be well served, and the slow burn pays off rather than fizzling.

An Immersive, Familiar World

Hart’s fae kingdom is richly drawn — frozen courts, looming war, a magic system grounded in alchemy and the mysterious quicksilver that gives the book its name. The worldbuilding is one of the novel’s pleasures, immersive enough to disappear into for hours. It is also, by the genre’s standards, familiar: portal fantasies, fae courts, and war-torn magical kingdoms are well-trodden ground, and readers steeped in the category will recognise the shapes. Hart’s execution — the specificity of the alchemy, the voice of her heroine, the heat of the romance — is what makes the familiar feel fresh.

The Length Question

At more than six hundred pages, Quicksilver is a commitment, and the page count is a double-edged sword. For readers who love to sink into a long, immersive world and let a slow burn simmer, the size is a feature — there is room to live in Yvelia and to let the relationship develop at length. For others, the middle stretches sag, with the plot occasionally treading water between its strong opening and explosive finale. It is a book best approached when you are in the mood to settle in rather than race through.

A Series With Its Hook Set

True to genre form, Quicksilver ends on a cliffhanger built to make the sequel mandatory, escalating both the romantic and the military stakes just as the pieces align. The Fae & Alchemy series has a devoted and growing readership, and the first book does its foundational work well: it establishes a magnetic heroine, a charged central relationship, and a war whose outcome readers will want to follow. The hook is sharp enough that finishing without the next volume in reach is a minor act of self-harm.

The Verdict

Quicksilver is a prime example of romantasy doing what its biggest audience loves: a long, immersive, spicy enemies-to-lovers fae fantasy carried by a heroine with a voice you actually want to spend six hundred pages with. It is not reinventing the form, but it is delivering its pleasures at scale and with real craft, and its breakout success in 2024 is well earned. For fans of the deep end of the genre, it is a near-essential addition to the shelf.

Two Worlds, One Heroine

One of Quicksilver’s smarter structural choices is the contrast between its two settings. Saeris’s home city of Zilvaren is a place of scorching scarcity — a desert dystopia where water is rationed and survival is brutal — and that deprivation has forged her into the hard, resourceful thief the reader meets at the start. When the portal drops her into the frozen fae kingdom of Yvelia, the inversion is total: cold instead of heat, abundance and ancient magic instead of want, courtly intrigue instead of street-level survival. Hart uses the juxtaposition to keep Saeris perpetually off-balance and the reader perpetually oriented through her eyes, and it gives the worldbuilding a built-in sense of wonder — everything in Yvelia is strange not just to us but to a heroine who has never seen snow, let alone fae magic. It also deepens Saeris’s characterisation: her wariness, her instinct to steal and hoard, her refusal to trust, all read as the rational scars of where she comes from rather than generic prickliness. The two-world design does real narrative work, and it is one of the reasons the long page count earns its length: there is genuinely a lot of world to discover.

Our rating: 4.2/5 — A long, immersive, spicy enemies-to-lovers fae romantasy whose sharp-witted heroine and strong banter make its 2024 breakout entirely deserved.
