Kim Harrison's Hollows series is one of those rare paranormal romance worlds you don't leave easily. Set in a Cincinnati where a bioengineered tomato wiped out a significant chunk of humanity forty years ago, exposing the existence of witches, vampires, werewolves, and pixies to the surviving human population, it follows witch-and-runner Rachel Morgan across thirteen books, a handful of novellas, and more found family dynamics than most series manage in twice the page count. Rachel is reckless, principled, and deeply bad at self-preservation, and we have adored her for it since Dead Witch Walking dropped in 2004.
The reading order matters here more than in almost any other urban fantasy series. Harrison seeds plot threads in book one that don't pay off until book eight or nine. Villain motivations shift. Character loyalties fracture and rebuild. The romance subplots (yes, plural, yes, complicated) develop alongside the mystery-of-the-week structure rather than replacing it. Starting mid-series is genuinely disorienting. And the content warnings accumulate: blood magic, assault history, addiction as metaphor, and a vampire lore system that gets uncomfortably intimate before it gets consensual. None of that is a deterrent if you know it's coming.
Since the Hollows books themselves aren't yet in our database, we've pulled together the paranormal romance and romantasy series that scratch the same itch: strong heroines with real agency, found families built from unlikely combinations, vampire politics with actual stakes, and worlds where moral ambiguity is a feature rather than a bug. These are the reads we'd hand to someone who just finished A Fistful of Charms and needs something to tide them over.

Start HuntingStart Here: Paranormal Worlds with Deep Lore
The Hollows works because Harrison built a complete alternate history before she wrote a single scene. These series have that same density — world-building that rewards readers who pay attention.
Magic Bleeds
Kate Daniels is the closest thing urban fantasy has to a Rachel Morgan equivalent. Wisecracking mercenary in a post-Shift Atlanta where magic and technology alternate unpredictably, Kate spends most of this series entry finally colliding with Curran, the Beast Lord she's been circling for three books. The slow burn payoff is significant. The supernatural mystery involves a plague, ancient gods, and Atlanta's shapeshifter politics. Ilona Andrews writes ensemble casts the way Harrison does: every side character has their own life happening offscreen.
Shadowfever
Mac Lane starts the Fever series as a bubbly sorority girl from Georgia and ends it as something entirely different. Shadowfever is the conclusion to the original five-book arc, and it detonates every secret Harrison-style: things you thought you understood from book one turn out to be something else entirely. The Fae lore is intricate and genuinely unsettling. The morally gray MMC in Jericho Barrons is one of the most divisive in the genre — readers either find him compelling or completely unacceptable, and both reactions are understandable. Content warnings for dubcon in earlier books carry through here.
House of Earth and Blood
Crescent City is urban fantasy in a fantasy skin — a city where Fae, angels, shifters, and humans all coexist under an uneasy political structure not entirely unlike Harrison's Cincinnati. Bryce Quinlan is grieving her best friends, who were murdered during a demon attack, and the investigation that follows pulls in a soldier with his own secrets. This book runs long and takes its time building the found family before it tears it apart. The Hollows readers will recognize the specific pleasure of a world where the supernatural is mundane and the mundane is still dangerous.
The Vampire Politics Shelf
Harrison's vampires are unusual — the living and undead versions have different rules, different power dynamics, and different relationships with the humans and Inderlanders around them. These books take vampire society equally seriously.
Last Sacrifice
Rose Hathaway and Rachel Morgan would have a lot to talk about. Both are physically capable women who keep throwing themselves between their people and whatever wants to kill them that week. Last Sacrifice closes the original Vampire Academy arc with Rose framed for murder while her best friend navigates royal succession politics. The vampire society Mead built across six books has its own hierarchy, bloodlust mechanics, and class system — lighter on the lore density than Harrison but with a similarly warm found family at its core. The bodyguard romance through the series is excellent slow burn.
Lover at Last
The Black Dagger Brotherhood is the paranormal romance equivalent of a 21-book found family novel, with vampire warriors and the humans and other beings they love. Lover at Last is the long-awaited book for Qhuinn and Blay, two men whose relationship has been building in the background since early in the series. Ward's vampires have their own biology, their own social codes, and a Brotherhood dynamic that functions like a very violent, very loyal family. The spice is significant. The emotional payoff for this particular couple is substantial if you've been following along.
The Ashes and the Star-Cursed King
If Harrison's vampire lore appeals to you specifically, Broadbent's Crowns of Nyaxia series might be the best current romantasy equivalent. The vampire society here has real internal complexity — competing houses, a goddess with her own agenda, and a power structure that has specific costs. Oraya is a human woman who grew up inside vampire politics and understands exactly how precarious her position is. The MMC, Raihn, is a former enemy who is now technically her husband, which creates friction that plays out across roughly 600 pages of gorgeous tension. Content warnings for violence and political brutality.
Found Family as Load-Bearing Wall
One thing Harrison does better than most is make the found family feel genuinely chosen rather than plot-convenient. Jenks and Ivy aren't just sidekicks — they have their own lives, their own grief, their own character arcs. These reads treat ensemble casts the same way.
Vision in Silver
The Others series is lower spice than most of these recommendations and builds one of the more unusual found families we've encountered: a human woman named Meg who can see the future when her skin is cut, living among terra indigene (earth natives) who are barely tolerating humanity's continued existence on their continent. Simon Wolfgard falls first, and it takes the entire series for either of them to name what's happening. What Bishop does exceptionally well is the texture of daily life inside an impossible community — the same quality that makes scenes at Vampiric Charms or the Hollows church feel real.
Ruby Fever
Andrews shows up twice on this list because they're the genre's most consistent writers of ensemble paranormal fiction with genuine found family bones. Ruby Fever closes the Hidden Legacy series, and the Baylor family at the center of it has been one of the most satisfying group dynamics in the paranormal romance space for six books. Catalina is the quieter, more controlled sister to Nevada (the series' original protagonist), and watching her finally crack under pressure while also falling apart over Alessandro is extremely good. The supernatural mystery structure will feel immediately comfortable for Hollows readers.
Long Series with Big Payoffs
Thirteen books is a commitment, and Hollows readers know it. Here are series where staying in for the long haul is unambiguously worth it.
Archangel's Consort
Elena Deveraux is a vampire hunter who can smell angels — a skill that puts her directly in Raphael's orbit, who is one of the most powerful archangels alive and not accustomed to anything he can't control. The Guild Hunter series runs 16 books and the central relationship between Elena and Raphael develops across all of them rather than resolving in book one. Archangel's Consort is the book where the world-building stakes get genuinely alarming: something ancient is waking up. Singh writes possessive heroes who are compelling rather than suffocating, which is a difficult balance, and gets it right here.
Acheron
Acheron is the book Dark-Hunter readers work toward for fourteen books. He's the series' most powerful and most damaged figure — an ancient god running an organization of dead warriors who hunt demons — and his backstory, which takes up the first half of this 700-page entry, is genuinely devastating. Content warnings for sexual abuse and severe trauma. The second half is the romance, and it pays off in proportion to how hard the first half is. For Hollows readers who love the sense that their protagonist is always three steps from catastrophe and five steps from being held accountable for her own choices, Acheron's particular flavor of earned happiness will hit.
