You finished Fourth Wing and Iron Flame. Now what? These 20 books match what made Yarros's series so addictive.
What made Fourth Wing work: enemies-to-lovers with actual history between the characters, a war college setting with real stakes, dragons as characters rather than vehicles, high heat that earns its place in the plot, and a female protagonist who isn't protected — she's fighting. These 20 books match one or more of those elements.
Organized by how closely they match different aspects of the Yarros experience.
The book most frequently recommended to Fourth Wing readers. Rhysand is the Xaden equivalent — established as dangerous, gradually revealed as protective. Maas builds the romance through the same slow reveal that Yarros uses, and the Illyrian war training sequences have the same physicality as Basgiath. ACOMAF is a better single book than Fourth Wing; the broader series is messier.
Get A Court of Mist and Fury →Napoleonic Wars with dragon air corps. Captain Laurence bonds with a Chinese imperial dragon named Temeraire, and the series follows their military campaigns and growing relationship across nine books. Novik's dragons are intelligent, opinionated characters — the bond between rider and dragon has the same emotional weight as in Fourth Wing. No romance with Temeraire; the human relationships are slower to develop.
Get His Majesty's Dragon →The forbidden romance structure is closest to Fourth Wing — Poppy can't be with Hawke for political reasons that compound over the series. Armentrout's worldbuilding is less detailed than Yarros's but the emotional momentum is similar. The most-recommended alternative for readers who specifically want the high-heat forbidden romantasy experience.
Get From Blood and Ash →The most similar in terms of political sophistication. Lara's mission gives the enemies dynamic real consequences — she can't just stop being a spy. Jensen writes the romantic tension through the same "we shouldn't be doing this" pressure that Yarros uses, and the world-building is unusually detailed for the genre.
Get The Bridge Kingdom →Sera is trained from birth to be the God of Death's consort. The mythology is denser than most Armentrout and the forbidden element is structural rather than situational. Readers who want more lore alongside the heat will prefer this over the main Blood and Ash series.
Get A Shadow in the Ember →Twin sisters enter a Fae magic academy where everyone wants them gone. The bully-romance structure is more extreme than Fourth Wing's enemies dynamic, but the magic school setting and the multiple antagonistic relationships hit the same notes. Nine books in the series — highly committed readers only.
Get Zodiac Academy →If you haven't read ACOTAR, start here before ACOMAF. The first book is slower and less explicit but sets up everything that makes the second book work. Feyre's arc from hunter to prisoner to something more powerful is the closest character equivalent to Violet's arc in Fourth Wing.
Get A Court of Thorns and Roses →YA — less explicit than Fourth Wing — but the enemies dynamic between Jude and Cardan is the most structurally sophisticated in the genre. Both characters have genuine reasons to be enemies, and neither is simply softened into a love interest. The power reversal is well-executed and unexpected.
Get The Cruel Prince →Eight books in the Throne of Glass series. The competition-for-champion setting in book one is structurally similar to the rider trials at Basgiath. Maas's protagonist Celaena is a trained assassin rather than a reluctant warrior — more agency from page one than Violet. YA throughout; the explicit content from ACOTAR is absent.
Get Throne of Glass →The ur-text for dragon rider fiction. A farm boy finds a dragon egg and is pulled into a war between the Riders and the empire that destroyed them. The bond between Eragon and Saphira is emotional rather than romantic; the romance in the series is slower than Fourth Wing. Essential reading for understanding dragon rider fiction as a genre.
Get Eragon →A girl trained at a convent that is also a school for killers. The Abeth setting is darker than Basgiath and the romance is less central, but the martial academy structure and the loyalty-under-pressure between students is the same emotional core. Lawrence writes female friendship with unusual care for the genre.
Get The Red Sister →If what you loved about Fourth Wing was primarily the dark romance and the Xaden dynamic, Haunting Adeline is the most explicit version of that character type. No fantasy setting — gothic manor, stalker romance, maximum heat. Read content warnings before starting.
Get Haunting Adeline →Contemporary equivalent of the Xaden dynamic — a cold, obsessive man who has been watching and protecting from a distance. The secret-keeping structure mirrors Fourth Wing's reveals. Less heat than Yarros but the emotional beats are similar.
Get Twisted Love →The direct sequel to Fourth Wing. Yarros expands the world, increases the stakes, and the heat escalates significantly. Most readers consider it better than the first book; some find the pacing slower in the middle. Essential if you want to know what happens to Violet and Xaden.
Get Iron Flame →1800s Sicily, demons, murder mystery. Maniscalco writes atmospheric historical settings with high-tension romance. Lighter on explicit content than Fourth Wing; heavier on atmosphere and Gothic detail. Good for readers who want the romantic tension without the high heat.
Get Kingdom of the Wicked →Maas's most recent series — contemporary urban fantasy setting with Fae, angels, wolves, and merpeople in a city called Crescent City. More mystery-driven than ACOTAR and Fourth Wing; the romance is central but slower to develop. The series crosses over with ACOTAR in ways that reward readers who've done both.
Get House of Earth and Blood →A girl enters the Unseelie court to rescue her sister and gets caught between two princes. The dual love interest structure is different from Fourth Wing's singular focus but the court politics and the forbidden dynamic are similar. Better for readers who liked the political scheming in Yarros's world-building.
Get These Hollow Vows →Six magicians competing for access to the world's most powerful library. The dark academic energy is similar to Basgiath's war college atmosphere — high stakes, morally grey characters, competition with real consequences. Less explicit than Fourth Wing; the morality is more genuinely complex.
Get The Atlas Six →Chinese mythology, a quest through the immortal realm, and a slow-burn romance with someone from the opposing side. Less heat than Fourth Wing but the loyalty-vs-duty conflict — Xingyin choosing between her mission and the person she loves — mirrors Violet's central dilemma more closely than most alternatives.
Get Daughter of the Moon Goddess →A magical performance where the prizes are real and nothing is what it seems. YA — significantly less heat than Fourth Wing — but the atmosphere of a game where the stakes are life and the tension between what's shown and what's real is similar to the deception layers in Yarros's series. Best for younger readers or Fourth Wing fans who want something lighter.
