The Juniper Books Spice Rating: 2026 Edition

The Juniper Books Spice Rating: 2026 Edition

Turning up the heat (again)

You asked, we delivered: our spice rankings are back. When we first published A Definitive Spice Ranking of the Hottest Fantasy Romance Series, six series made the cut: Shades of Magic, Throne of Glass, All Souls, Outlander, A Court of Thorns and Roses, and Blood and Ash. A lot of new books have landed on readers' nightstands since then, so here are fifteen more of the most talked-about romance reads, from swoony slow burns to series that should come with a fire extinguisher.

Whether you're picking your next read, choosing a book club title, or buying for someone whose comfort zone you'd rather not guess at, here's how our scale works:

  • 0/5 – Sweet: Longing looks, maybe a kiss. Safe for any reader.
  • 1/5 – Warm: Real romantic tension, closed doors or fade-to-black.
  • 2/5 – Simmering: A few on-page moments, kept brief and soft-focus.
  • 3/5 – Steamy: Open-door scenes with some detail, still plot-first.
  • 4/5 – Hot: Frequent, detailed love scenes woven through the story.
  • 5/5 – Scorching: Explicit, plentiful, and absolutely the point.

Book Lovers Deluxe Edition by Emily Henry

Book Lovers: Deluxe Edition by Emily Henry

Spice: 2/5 · Series status: Standalone

Steamy: 3/5
Green Creek series book set by TJ Klune in Juniper Books covers, with two wolves embracing across the spines

Green Creek Series by TJ Klune

Spice: 3/5 · Series status: Complete

Werewolf packs, found family, and a love story that will wreck you in the best way. Klune's open-door scenes are tender and emotional rather than graphic.

STEMinist romance book set by Ali Hazelwood from Juniper Books

Ali Hazelwood's STEMinist Romances by Ali Hazelwood

Spice: 3/5 · Series status: Standalones

No dragons here, just fake-dating PhD candidates, grumpy professors, and more chemistry than a lab. Starting with The Love Hypothesis, Hazelwood pairs laugh-out-loud banter with a few genuinely steamy scenes per book.

Crowns of Nyaxia by Carissa Broadbent

Spice: 3/5 · Series status: Ongoing

A human raised by the vampire king enters a deadly tournament and forms a dangerous alliance with a rival she should be trying to kill. The tension simmers through most of The Serpent and the Wings of Night before boiling over, and the heat rises as the series goes on.

Hot: 4/5
Fourth Wing Deluxe Special Edition by Rebecca Yarros

Fourth Wing by Rebecca Yarros

Dragons, a deadly war college, and Xaden Riorson. Violet's survival story comes with detailed scenes that made BookTok collectively fan itself.

Quicksilver by Callie Hart

Spice: 4/5 · Series status: Ongoing

A thief from a desert city stumbles through a portal into a frozen fae realm, straight into the path of a brooding warrior called Kingfisher. The burn is slow, but once it catches, it does not hold back.

The Plated Prisoner by Raven Kennedy

Spice: 4/5 · Series status: Complete

A dark retelling of the King Midas myth, told by the gold-touched favored he keeps in a gilded cage. Book one is a slow burn, but the later books more than earn this spot.

Twisted Series by Ana Huang 4 Books Collection - Books2Door – American Bookworm

Twisted Series by Ana Huang

Spice: 4/5 · Series status: Complete

Four standalone romances and four very morally gray men, starting with Twisted Love. No magic required: the scenes are frequent, detailed, and a big part of why BookTok can't stop talking about them.

Chestnut Springs Series by Elsie Silver: 4 Books Collection Set - Fiction - Paperback

Chestnut Springs by Elsie Silver

Spice: 4/5 · Series status: Complete

Trade the dragons for cowboys. This small-town series follows the Eaton brothers and the women who knock them off balance, starting with Flawless, and the heat is as reliable as the banter.

Scorching: 5/5

Spice: 5/5 · Series status: 10 books, each a new couple
