Portal fantasy and enemies to lovers should be a perfect pairing. You've got a character dropped into an alien world, completely stripped of context and safety nets, and then forced to depend on someone who either actively resents them or has every reason to. The power imbalance is baked in. The tension writes itself. And yet the combo is rarer than you'd expect — most portal fantasy books lean into wonder and chosen-one arcs, and the romance, when it's there, tends more toward protector dynamics or fated mates than the friction-heavy enemies arc.
We tagged both tropes across 1,000+ books on this site and found 11 that carry both. We're recommending 10 of them here. A few are mid-series entries, which matters — some portal fantasy romances don't really ignite until book two or three, after the world has been established and the characters have had time to genuinely wound each other. We've noted where that's the case. What we're not including: books where "enemies" just means "they were slightly rude at first." The tension has to be real, and it has to be worth it.

Start HuntingThe Heavy Hitters (You've Probably Heard of These, But They Earn the Hype)
A Court of Mist and Fury
Feyre is trapped in a trauma spiral and an engagement she can't escape, and Rhysand — who spent most of book one being a genuine threat — turns out to be the only one who can pull her out of it. The portal fantasy element kicks in hard here: Feyre is already a human woman in a Fae world, but ACOMAF drops her into Velaris and the Night Court in a way that feels like a second arrival, a second world reveal. The enemies arc is real. Feyre has actual reasons to hate Rhys. The slow dismantling of that hostility is the whole engine of this book, and it runs for 600 pages without losing steam.
House of Earth and Blood
Maas twice on the same list feels like a cheat, but the Crescent City series earns its own spot because the vibe is completely different — urban fantasy setting, grief-driven plot, and a detective investigation spine under all the romance. Bryce and Hunt start at open hostility, not reluctant alliance, and the portal fantasy element (Midgard as a world apart, with other realms bleeding in) is more atmospheric than literal, but it qualifies. The enemies dynamic here has actual stakes attached to it. Hunt has orders that conflict with protecting Bryce. That tension doesn't evaporate just because the romance heats up.
The Kingdom of Copper
This is the quieter pick on the list and the one we'd push hardest toward readers who are tired of enemies-to-lovers done loudly. Nahri was summoned to Daevabad in book one — classical portal fantasy with djinn politics instead of fae courts — and by book two she's trapped inside a marriage she didn't choose, in a city that doesn't trust her, surrounded by two men she feels dangerously toward for very different reasons. The enemies dynamic here is political and personal at once. It's also one of the few entries on this list where the spice stays low and the emotional tension does all the heavy lifting. The slowest burn here by a significant margin, and worth every page.
Mid-Series Payoffs (Start From Book One)
The Ashes and the Star-Cursed King
Oraya was raised in a vampire kingdom where she was simultaneously the king's ward and the population's punching bag, human in a world built to destroy her. Book two throws her directly into conflict with Raihn — a man she has real reasons to hate, reasons that accumulate as more truth comes out — and the portal-to-another-realm framework deepens as Nyaxia's world expands. Broadbent writes enemies to lovers with a particular cruelty: she lets both characters be wrong about each other in specific, earned ways, so when they stop being wrong it lands hard. The grovel in this one is legitimate.
Zodiac Academy: Sorrow and Starlight
Nobody is picking up book eight of a series without context, so we'll be direct: if you've made it this far into Zodiac Academy, this is what you stayed for. The Vega twins were dropped into Solaria — a world of fae magic, astrological power systems, and people who wanted them dead on arrival — and the enemies dynamics have been building across thousands of pages. Book eight is the near-end payoff, the one where the sacrifices hit and the emotional debts come due. The portal fantasy frame (Solaria as an entirely separate world the twins are native to but were kept from) gives the whole series its particular flavor of being a stranger in your own inheritance.
Gleam
Auren has spent her whole life as King Midas's most prized possession, and Gleam is the book where she finally starts to understand what that cost her. The portal fantasy element is literal — she ends up in the Fourth Kingdom, a world as different from the gilded court as possible — and the enemies dynamic with Slade is the kind where both parties would prefer to be anywhere else, except they keep ending up in the same room. Kennedy's particular skill is writing heroines who are figuring out their own agency in real time, and the romance reflects that. Slade falls first, and it's obvious to everyone except Auren.
Standalones and Shorter Series (Lower Commitment, High Return)
The Jasad Crown
The Scorched Throne duology is the most underread series on this list, and we'd argue it has one of the most genuinely fraught enemies dynamics in the portal fantasy space. Sylvia was a fugitive queen hiding her identity in an empire that destroyed her homeland. Arin was one of the reasons that empire held together. Their alliance is practical and their hostility is political and neither of those things fully explains the other. Book two, The Jasad Crown, is where the reckoning arrives: her identity is out, her kingdom is a memory she has to rebuild, and Arin is now an obstacle who is also the person she most trusts. Only two books to read before this one.
Shield of Sparrows
A standalone, which is rare in this genre combination. Perry drops a princess into a court politics nightmare where the man she's supposed to despise is also the only one with information she needs, and layers fake dating over the enemies dynamic in a way that shouldn't work as well as it does. The portal fantasy element is more "different kingdom with its own rules and creatures" than dimension-crossing, but it reads as fully other-world. Good option if you want the enemies tension without committing to a multi-book series first.
For Readers Who Want the Monsters and the Mayhem
Taming Demons for Beginners
The lightest-spice entry on this list, and the one we'd hand to readers who love enemies to lovers but aren't sure they want full-tilt spicy romantasy. Robin accidentally binds a demon to her service through a grimoire she wasn't supposed to touch. Zylas is furious, lethal, and not remotely interested in being anyone's servant. The portal fantasy element is the demon realm bleeding into the human one, with Zylas operating as a visitor in a world that wants him dead. The banter is good. The enemies arc is slow enough to actually hurt. And Marie doesn't rush the romance, which is either a selling point or a dealbreaker depending on your patience for a burn that's really a simmer.
Wyn
The Monstrous series is set in a post-collapse wasteland where humans and monsters coexist badly, and Wyn is the entry where that tension is most personal. A human soldier and a winged monster are forced to travel together through the Wastes, and the hostility between them is the kind born from fear and ideology rather than just personality clash. What makes it work as a portal fantasy is that the Wastes themselves function as a wholly other world, and each book drops you into a different pocket of it. The enemies-to-lovers arc here is quiet and physical and earned. Not the loudest book on this list, which is exactly why it deserves a spot.
