5 Interconnected Romance Book Series That Readers Absolutely Love

Many romance novels exist as part of a series. For example, the popular "Bridgerton" novels are set sequentially, with each story building on the previous ones. But for those who love the complex world building of a series, but don't necessarily like feeling locked into an unwieldy multi-book story, there's another wonderful option: an interconnected series. Instead of one continuous narrative, these series offer multiple books that exist within the same fictional universe, but they are each a complete and self-contained story. That means, they don't need to be read progressively. You can even just read one.

Part of the charm of an interconnected but standalone novel is that it's less of a commitment than diving straight into the full series. "I prefer loosely connected stories or standalone books because it's rare that a series doesn't have at least one or two stinkers, or some books/characters that I'm just not interested in," wrote one Reddit user. Readers can hone in on the particular stories they want to read, and skip the ones they don't. "Interconnected but stand-alone is honestly my favourite thing in romance," wrote another Reddit user. "I want to be able to just pick up a book and read it based on whether that particular romance/ couple sounds interesting to me, without reading other ones first."

Liz Tomforde's "Windy City" series of books all take place in, predictably, the city of Chicago. These contemporary romances are all set against the backdrop of the professional sports world, and her various leading men include a hockey player, a basketball player, and a baseball player. That means they're among the best sports romance books for your next read. But while these novels touch each other tangentially, with multiple characters belonging to the same closely bonded friendship group, each book centers on a new couple and their unique love story.

Fans adore the electric chemistry that Tomforde conjures on the page. "I honestly have no words — this series was fantastic. Every time I finished a book, I thought 'That's it, that's my favourite couple,' and then I'd start the next one and somehow fall even harder," wrote one Reddit user. "I was OBSESSED with all of them." In particular, readers appreciate that the stories are character-driven and feature a recurring "found family" dynamic. Even better, the romantic plots feel well earned. "I love that the books take their time and flesh out the characters for us so that they're three-dimensional people," wrote one Reddit user. "There's no haphazard mad rush to an obligatory [happy ever after]."

The "Twisted" series by fan-favorite Ana Huang — whose steamy romance novel "King of Sloth" blew up the Kindle charts – is a four-part contemporary romance series that circles around a group of college friends. Ava, Bridget, Jules and Stella met in school, and their close bond is at the center of the series. Each novel follows one woman's love story, and adheres to a beloved genre trope. While the books have a rough reading chronology, fans explain that you won't miss much if you skip installments or mix up the reading order. "I personally loved all of them," wrote one Reddit user, noting that it's possible to read books from the series as standalone novels. "You'll miss a little context with some of the other characters, but nothing that would totally hinder you from being able to read it by itself."

Fans praised the books for their relatable characters and spicy sex scenes, as well as Huang's ability to refresh romance tropes like fake dating and enemies-to-lovers. In particular, readers praised the originality of "Twisted Games," but "Twisted Hate" drew the most divided opinions. "'Twisted Games' is for sure the best in the series," wrote one Reddit user.

In the five-part "Chestnut Springs" series, Elsie Silver weaves together several romance stories that are all connected by their setting: the fictional Wishing Well Ranch. Though they don't necessarily need to be read in a specific order, all the books exist within the same timeline and feature recurring characters, particularly the Eaton family. Even better, the series exists within Silver's larger extended world, which includes other "small town" series like the "Gold Rush Ranch" series and "Rose Hill" series. Readers familiar with those books will recognize characters and references that appear in the "Chestnut Springs" series.

Readers gushed about the experience of being immersed in the world of Chestnut Springs. "This series will live in my head forever, I can just tell," wrote one Reddit user. "I've never read a series as good as this one and I'm both happy I read it and sad I will never get to experience it for the first time again." Fans stressed that these books can be enjoyed out of order, or even alone. "There's no overarching plot which goes across multiple books and the only spoilers would be which couples end to together, which is usually pretty obvious just from the blurb of their book," explained one Reddit user.

The "Off-Campus" series by Elle Kennedy centers on four college roommates who all play hockey. In each of these contemporary romance novels, a different roommate meets a strong-willed woman and finds himself falling in love, which means they're among the essential hockey romance books to check out if you're a rookie to the genre. The popular series also kicked off a spin-off series called "Briar U." Since each novel focuses on a different couple's love story, each book can be enjoyed separately, or out of order. "Each book is written as a complete standalone!" explained Kennedy during a Goodreads Q&A. "You do see past characters in some of the future books, so you may prefer to start at the beginning of 'Off-Campus' before reading 'Briar U,' but it's totally not required."

The series remains beloved by romance fans, thanks to the clever banter and spicy romance. Readers also praised how the characters' athletic lives interacted with the romantic plots. "These books are what got me back into reading, and specifically into romance," wrote one Reddit user. "It also means that I have a huge soft spot for sports romance (I just love sport and the idea that it adds additional stakes)." In fact, these books are so popular that they were adapted into a 2026 television series by Amazon Prime.

For readers who love fantasy romance stories, the "Prince of Sin" series by Kerri Maniscalco is a popular series set in a magical realm. Though you don't need to have read Maniscalco's other works to enjoy these novels, they are set in the same universe as her previous "Kingdom of the Wicked" trilogy. Better yet, each of the three current books – there are seven planned, one for each of the Bible's deadly sins – follows an individual couple, which means these books can be enjoyed independently despite their connections to one another. Many of the characters have even already appeared throughout Maniscalco's other works.

Fans loved the "Prince of Sin" series for its comprehensive world building and incredible character depth. "I stumbled across and devoured 'Throne of the Fallen.' I thought it was excellently done. Great storyline, pacing, well developed characters, magic system, writing, banter/levity," wrote one Reddit user. "It is a chef's kiss of an escape novel with exactly the right amount of spice." Readers also adored the propulsive plotting, which delivered some genuine surprises. "I loved it, so many twists and turns," wrote another Reddit user.
