Fall Into Place by Kristyn J. Miller – Sep. 8
Friends-to-lovers romance is always more irresistible when things are anything but straightforward between our two leads, and that’s precisely what we get with Kristyn J. Miller’s Fall Into Place. The story begins with Lenore French, a struggling-artist-turned-barista living in Manhattan who returns to rural Vermont after the death of her grandmother. Her grandma practically raised Lenore and her big brother, Damien, after their mother dropped them off on her doorstep, and now Lenore feels saddled with the loss, as well as finalizing the sale of her family’s landmark apple orchard at French Hill Farm.
Callan Bradford’s dad was groundskeeper of the orchard all his life, but after an injury, Callan has stepped into that role himself. As kids, he and Damien were best friends, which meant Lenore was absolutely off-limits. He sensed a spark with Lenore years ago at Damien’s wedding, but the moment passed. Lenore later got engaged, and they both thought the rest would be history.
But just because Lenore returns a single woman doesn’t mean the doors are open for their unspoken mutual crush to flourish. She’s as unsure of herself as ever as her artistic ambitions remain abandoned, and she’s struggling to say goodbye, not just to her grandmother, but to the place she once called home. Callan’s future is equally uncertain, with his livelihood tied to the orchard. The new owners may decide to let him go, and who is he if he’s not the groundskeeper at French Hill Farm?
A reunion between the two sees sparks flying, the electricity between them as electric as ever, despite their qualms about a potential romance. Plus, Lenore will be back in New York within weeks, and Callan’s life seems like a dead-end, even if he doesn’t get unceremoniously fired once the dust settles. They feel as if they belong to two different worlds, with a major obstacle and years of unsaid feelings bubbling between them—but is that really so impossible to overcome?
Fall Into Place is a sweet (and occasionally spicy) dual-perspective romance that’s driven by its believable, grounded characters in a lived-in world. It perfectly sets the scene for this fall romance and makes it easy to root for Lenore and Callan, even when we’re internally yelling at them to get on the same page. Plus, we never imagined a tick-removal scene could be so swoon-worthy.

So It Grows by Andie Burke – Sep. 22
So It Grows is a more playful (and frequently raunchy) rivals-to-lovers story, and though the story begins in summer and takes place over the changing seasons, it’s dripping with cozy fall vibes.
It’s the story of Felicity Gallagher, who feels like she’s getting a second shot at life after her Aunt Jeannie passes and leaves her plant shop in Kansas. After her traumatic injury at her former workplace as a nurse, she’s still in recovery mode, both emotionally and physically, but she’s willing to do absolutely anything to make things work, often to her own detriment.
Nicolas Holm-Bozic is the hunky head chef of the brand-new, super-trendy mac and cheese restaurant that takes up shop next door. He’s a bit of a know-it-all who gives out advice too eagerly for Felicity’s liking, and immediately, she can’t stand him. They become instant enemies (even if it’s fully one-sided), with Felicity doing everything she can to ignore her work neighbor and keep on with things by herself.
But when a local developer comes up with a money-making scheme that threatens both businesses—and a local tree that’s meaningful to the community—with the construction of an ugly parking lot, Felicity begrudgingly forms a truce with her rival. Together, as they work to revitalize their shared space and sway the community to choose them over more parking, Felicity’s feelings thaw as she recognizes Nic’s generosity and openness. Their new friendship might bloom into something even bigger if she can put aside her prejudices against all people with Nick-adjacent names.
Felicity is so easy to love that it makes all of So It Grows hard to put down—especially because as readers, we don’t really hate Nic at all, and it’s all a matter of time before Felicity sees how unfairly she’s judged him. It’s occasionally crude in the best ways, with some very steamy scenes, thanks to an adorable duo, and the work Felicity does to reflect on the challenges of her past, moving beyond certain elements and learning to embrace others. We also adored the bold third act twist we never saw coming. This one’s poised to sweep readers off their feet.

Lucy Kline, Necromancer by Tom O’Donnell – Sep. 22
And finally, for something completely different, there’s the horror YA gem Lucy Kline, Necromancer by Tom O’Donnell.
The story begins with high schooler Lucy Kline, two years after her twin sister, Louisa, snuck out at night to see her boyfriend and was killed. No body was ever found, but Lucy’s confident about what happened. She took it upon herself to solve the murder and get the killer behind bars, not that she feels any better after what happened. She feels responsible for arguing with Louisa and letting her sneak out that night, and now, Louisa’s ghost haunts her most nights in her nightmares.
History seems to be repeated itself when another student, Lyra, goes missing under similar circumstances. Even stranger, the girl looks almost identical to Lucy and Louisa. She feels a responsibility to get to the bottom of this case, too—especially given that the prior arrest might mean an innocent man is in prison.
As she investigates the crime, all of the clues point to the impossible, leading back to a long-dead necromancer. In the meantime, she recruits her neighbor, Howie, who’s still not over his feelings for Louisa, plus a retired history professor she meets on Zoom, hoping to save Lyra’s life before it’s too late. It turns out that in order to defeat an undead necromancer, you might need to learn a thing or two about raising the dead yourself.
Lucy Kline, Necromancer has a little bit of everything, from high school social drama to complicated family relationships, detective work and, of course, a bit of the occult. While she’s not always exactly relatable, or even likeable, we still rally behind Lucy on her quest, and understand where she’s coming from when she treats people badly on her mission to stop more people from getting hurt. In the end, it manages to be a delightfully spooky mystery while also powerfully unpacking lessons about grief, loss and holding on to the ones you have while you can.
