The Complete Quicksilver Guide

Quicksilver appeared in late 2024 as a self-published doorstopper and became the romantasy story of that winter almost overnight. A sharp-tongued desert thief named Saeris Fane grabs a relic she should not touch, gets dragged through a gateway into a dying fae world, and lands in the orbit of Kingfisher, a scarred, infuriating fae warrior with a talent for making everything worse before he makes it better. BookTok did the rest: the book hit the bestseller lists, Hachette picked up the series, and the phrase good girl acquired a fandom of its own.

The Fae and Alchemy series is a trilogy and the order is strict: Quicksilver (2024), then Brimstone (2025), with the untitled third book concluding the story. Book three's schedule has moved around, originally listed for late 2026 before being pushed back, with the latest word pointing to 2027, so build your expectations accordingly. These are direct continuations, not standalone adventures. Brimstone opens on the consequences of Quicksilver's ending and closes on a cliffhanger of its own, so readers who hate waiting may want to let the finale land first. Both published books are on our shelves.

This is one of the spicier big series on the site, a solid 4 on our scale, explicit and frequent once it gets going, with the infamous praise-kink scenes doing exactly what the internet says they do. Content notes: graphic violence and torture, captivity, a war-scarred love interest with a genuinely dark past, blood magic and gore, and alcohol dependence portrayed on the page.

What Hart does well is chemistry with an actual edge. Fisher is written as properly infuriating rather than cosmetically rude, Saeris gives as good as she gets and keeps her own agenda, and the alchemy-meets-fae worldbuilding is more distinctive than the genre average. The banter earns its reputation. Fair criticism: Quicksilver runs over a hundred chapters and feels it, with a middle section that wanders, and some plot mechanics bend suspiciously to put the leads where the romance needs them. Brimstone tightens the pacing but ends mid-crisis, which is either delicious or enraging depending on your tolerance.

If you came for the heat and the hostility, our enemies to lovers and fae romance trope pages are the natural next stop. From Blood and Ash matches the spice level across more books, ACOTAR supplies the comfort-food version of the fae court fantasy, and Crowns of Nyaxia is the pick when you want the same intensity with vampires instead of fae.
