Spicy Romance Books, Ranked by Readers

Short answer: the most-read spicy romance books right now are A Court of Thorns and Roses (Sarah J. Maas), A Court of Silver Flames (Sarah J. Maas), Quicksilver (Callie Hart), Haunting Adeline (H. D. Carlton) and The Serpent and the Wings of Night (Carissa Broadbent). Every book below is recorded as spicy or explicit in our data — open-door, on-page sex — and the list is ranked by how many readers reviewed it, not by anyone’s favourites.

How this list was built

PlotProse keeps a book dataset of 11,574 trope-tagged titles carrying 67,492 trope tags, each with a recorded heat level (sweet, steamy, spicy, explicit), primary subgenre, Amazon star rating and reader review count. For this page we kept only romances whose heat level is spicy or explicit, collapsed duplicate editions, dropped anything under 500 reviews and ranked the rest by reader review count. The 30 books below have 3,664,652 reader reviews between them and average 4.45 stars; 16 are recorded as spicy and 14 as explicit.

“Steamy” books — sex on the page but fewer scenes and less detail — are deliberately left off, which is why Fourth Wing and the Knockemout series are not here. If you want the whole heat range, the enemies to lovers books and slow burn romance books lists include steamy titles.

The 30 most-read spicy romance books

Star ratings and review counts are the figures recorded in our dataset at the last refresh and move over time. “Heat” is our extractor’s reading of the book: spicy means several detailed open-door scenes, explicit means the sex is frequent, graphic and central. “Subgenre” is the primary subgenre assigned; for series it can differ slightly between books.

Three kinds of spicy romance, and which one you want

The list splits cleanly into three shelves. Roughly 11 of the 30 are romantasy or paranormal (the Court of Thorns and Roses books, Quicksilver, Zodiac Academy, Blood and Ash, The Plated Prisoner), 16 are dark romance (Haunting Adeline, the Mindf*ck series, Credence, Den of Vipers), and 3 are contemporary (Twisted Games, Reckless, Wild Eyes). They read very differently:

• Spicy romantasy builds for hundreds of pages before the first scene and then delivers several. The heat is a payoff for the slow burn. Start with A Court of Thorns and Roses if you have not read it; Quicksilver if you have.
• Spicy dark romance is explicit early and often, and the sex is tangled up with danger, power and consent that is blurred on purpose. The dark romance books list covers this shelf in full, with content guidance.
• Spicy contemporary is the easiest entry point: modern settings, banter, a couple you would recognise, and open-door scenes that arrive at the pace of a real relationship. Twisted Games (bodyguard) and Reckless (small-town cowboy) are the two most-reviewed here.

Romance books for adults: what “spicy” actually promises

When readers search for romance books for adults or spicy romance, they are asking one question: is the door open? On this list it always is. What varies is frequency, explicitness and tone — and whether the sex is the point or a consequence of the story. A useful rule from the data: the higher a book sits on a “spicy” list while also carrying a 4.5+ star rating (A Court of Silver Flames, Paint It All Red, Gleam, Reckless), the more likely the heat is earned by the relationship rather than replacing it. Readers rate the romance, not the scene count.

Where to start, by what you already like

• If you read fantasy: A Court of Thorns and Roses, then A Court of Silver Flames — the latter is the spiciest of the series by a wide margin.
• If you want contemporary and funny: Reckless or Wild Eyes by Elsie Silver — small-town, open-door, warm.
• If you want billionaire or bodyguard: Twisted Games by Ana Huang.
• If you want dark: Haunting Adeline — and read the content warnings first.
• If you want explicit romantasy: Glint and Gleam (The Plated Prisoner) or The Wolf King.

Why spicy romance dominates the charts

High-heat romance outsells closed-door romance on Kindle by a distance, and the list shows why: it is where romantasy, dark romance and contemporary all meet. Readers who came for the dragons stayed for the heat; readers who came for the heat discovered the dragons. For authors, the lesson in the data is that heat is a multiplier on a story readers already want, not a substitute for one — the tropes still sell the book.
