Hey there everybody! Another month, another bunch of new books that are coming out! Yep, it’s The Most Intriguing New Books of September 2025. I know this is about a week later than I usually do it – I like to get it out by the first Tuesday of the month – but there was a lot going on last week, so I’m doing it now.

This used to be a quarterly post, but I’ve recently decided to do it monthly instead. Also, even though this post is about new releases, it’s primarily focused on fantasy and science fiction, as those are the genres I tend to prefer to read. (Not to say other genres won’t ever appear on these lists – it just isn’t super likely; it’s likely to be a very rare occurrence if it happens at all.)

If you’ve seen this post by me before, you know the drill; I’m only interested in these books – there’s no guarantee that I’m gonna read all of them. There’s not even a guarantee that I’m gonna read even half of them. We shall see. Anyway, let’s get going! This month there are eight books that have caught my eye. Eight. What a step up from the last few months! Ah Autumn, how I love thee…

RELEASING: September 2nd

In a world where magical beings, fey, are mistrusted and often institutionalized, a human brother and fey sister must team up to solve a bizarre murder in this 1920s-inspired queer teen fantasy novel.

In the city of Puck’s Port, where motorized vehicles fill the streets and new technological marvels abound, something rotten is lurking under the surface. A violent murder at the docks seems to point to a fey killer, igniting a powder keg of distrust between the city’s humans and its fey inhabitants — folks who wield wonderful but often uncontrollable magical power.

Gristle Senan Maxim Junior finds himself caught in the middle. Forced into the reluctant role of private investigator, like his late father, he’s working to solve the mystery of this fiery murder . . . mainly because his sister, Hawthorne Stregoni, is a fey herself with an unfortunate penchant for setting things ablaze.

Hawthorne is part of an experimental study to control feyism but struggles to keep her powerful magic in check in a country that hates what she is. Can she and Gristle work together to find the true instigator of the murder before it’s too late?

In this atmospheric and bewitching novel, Louisa Morgan reimagines the story of Morgan Le Fay, one of the most enigmatic and powerful women in Arthurian legend. 

To the other priestesses of the Nine, a powerful council at the Lady’s Temple, Morgana is haughty and arrogant as she performs feats of magic no human should be capable of. Rumors start that she must be a fearsome fae.

To King Arthur, Morgana is a trusted and devoted advisor, but his court is wary of her and her prodigious talent at divination. But his wife sees Morgana as a rival and a malevolent witch.

To Braithe, Morgana’s faithful acolyte, she is simply the most powerful priestess Camelot has seen.

A vampire who can’t remember his past and a witch with secrets of her own hit the road in this zany, cross-country romantic comedy from beloved author Jenna Levine.

Reformed bad witch Grizelda “Zelda” Watson had hoped to never see another vampire again when she slipped away to sunny California for a fresh start. She’d grown tired of them and their nonsense ages ago. But when a vampire with amnesia unexpectedly shows up on her doorstep with a letter from her old friend Reggie, and asks for her help, she can’t say no. Of course, it doesn’t hurt that Peter Elliott is tall and gorgeous, looks great in yoga shorts, and has the kind of dark hair and surly expression Zelda’s been a sucker for for hundreds of years.

Peter isn’t completely harmless—he is fanged, after all—but he’s harmless enough, and soon becomes the only person in Zelda’s new life who knows the truth about what she is. If she can help him decipher the cryptic notes in his journal, the only clues to his lost memories, she might as well try before sending him on his way.

But when an alarming message from Peter’s past coincides with a clear sign that Zelda can’t keep running from her own, they embark on a cross-country road trip for answers—only to find what they’re looking for in each other.

18-year-old Briar Winters must untangle the horrifying eldritch secrets of her picture-perfect coastal town in order to save the boy she loves after he disappears from time itself in this YA dark fantasy for fans of Bly Manor.

Historic Loch Creek is a witchy New England tourist trap—but it’s just a trap for Briar, who’s convinced she’ll die there among the waves that devoured her twin brother thirteen years ago. But when her best friend who she’s loved since childhood, Finn, vanishes from the seaside carnival, there’s only one person who can help Briar find him: Morgan, the standoffish goth girl everyone calls the town witch.

But as Briar uncovers secrets as deep and dark as the water that haunts her, it quickly becomes clear that Finn has gone much further than an out-of-state college. He’s lost in time, and neither of them are safe. The seductive yet evil underwater entity that intended to claim Briar’s body in more ways than one still needs its sacrifice . . .

And it’s too hungry to go unsated.

Equal parts steamy epic romance and pulse-pounding horror, This Raging Sea is a dark fantasy as sweepingly powerful as the ocean that threatens to consume everything and everyone Briar has ever loved—prepare to be devoured.

Godkiller meets Powerless in this epic gods-and-monsters romantic fantasy from British Fantasy Award-winning author Jen Williams.

Welcome to a world where gods and monsters roam the earth…

Elver is the guardian of the wild and dangerous monster forest. Saved from the brink of death by a god, her skin will poison anyone she touches.

Artair is on a mission – one that takes him face-to-face with Elver at her most ruthless. But her defenses are useless when she discovers he’s the only human impervious to her deadly gift. For Artair isn’t human: he’s one of the Sleepless, cursed to share his body with an evil spirit.

Lucian inhabits their body while Artair sleeps, and he is hell-bent on manipulating Elver for his dark purposes. But Elver is harbouring secrets too, and she has her own reasons for feigning an alliance with these two souls.

Caught in the crossfire of gods, monsters, and a dangerous magic they can barely understand, it is only a matter of time before the paths the three of them choose to take will set alight the very foundations of their world.

With a love triangle like you’ve never seen it, incredible world-building, brilliant writing, and high-stakes swoony romance, The Sleepless will have you spellbound.

An utterly fantastical and undeniably queer melding of Pride and Prejudice and Frankenstein that recasts Mary Bennet as an insatiable scientist, one who creates a monster in an attempt to save herself from spinsterdom

Mary Bennet is the middlest middle child of all time. Awkward, plain, and overlooked, she’s long been out of favor not only with her own family but with generations of readers of Pride and Prejudice.

But what was Mary really doing while her sisters were falling in love? Well, what does any bright, intrepid girl do in an age when brains and hard work are only valued if they come with a pretty face? Take to the attic and teach herself to reanimate the dead of course. The world refuses to make a place for peculiar Mary, but no Bennet sister ever gives up on happiness that easily. If it won’t give this fierce, lonely girl a place, she’ll carve one out herself. And if finding acceptance requires a husband, she’ll get one. Even if she has to make him herself, too.

However, Mary’s genius and determination aren’t enough to control what she unwittingly unleashes. Her desperate attempts to rein in the destruction wreaked by her creations leads her to forge a perhaps unlikely friendship with another brilliant young woman unlike any she’s ever known. As that friendship blossoms into something passionate and all-consuming, Mary begins to realize that she may have to choose between the acceptance she’s always fought for and true happiness.

True love knows no bounds. This premium, dual-sided volume includes two complete novellas bound together to create one can’t-miss collector’s item.

The first novella – told from Grim’s perspective – gives readers insight into his past: the motivations and events that cemented his fate as Isla’s eventual love interest.

The second is narrated by Oro and offers a window into his complex identity: that of a king torn between desire for justice and passion for the woman he loves more than anything. Grim and Oro: Dueling Crowns Edition includes key moments from the rulers’ love stories with Isla, expanded upon in their own voices.

Grim and Oro is certain to thrill readers and test allegiances, leaving new and longtime fans second-guessing who they’re rooting for in the breathtaking battle for Isla’s heart.

So yeah, these are all of the books releasing in September 2025 that I’m at least a little interested in. (One of them is almost certainly a hate read though, lol. I’m sure you can guess which one – hint: it’s Lightlark Saga adjacent.) What books are coming out soon that you’re looking forward to? Do we share some of the same ones?

As always, thank you all so much for reading, and I hope you have a great day/night!

See ya ~Mar
