Are There Books Like Grey Sister For Adult Readers?

Totally obsessed with the same blend of brutal training, found family, and razor-edged prose that 'Red Sister' delivers, I keep coming back to a few favorites that scratch that itch. 'Nevernight' is the first book I hand to friends who love assassin schools: it has poisonous wit, a protagonist bent on revenge, and classes that feel like apprenticeship by blood. 'Blood Song' gives the same monastery-to-warrior arc but with a stoic, internal hero whose training scenes hit emotionally hard. 'The Poppy War' is darker and war-torn, with ruthless military schooling and morally messy power that echoes the harsher beats of 'Red Sister'. If you want something with tender mentor-mentee bonds, pick up 'Assassin's Apprentice'—its slow-burning apprenticeship and found-family moments are beautifully done. For a YA-leaning, fast-paced rival to 'Red Sister', 'An Ember in the Ashes' offers brutal academies and survival through wit and grit. Finally, 'Traitor's Blade' feeds that swashbuckling, skill-focused thrill with a mercenary crew that grows into its own kind of family. Each of these scratched the same part of me that loved 'Red Sister', and I still catch myself thinking about certain fight scenes weeks later.

If you loved 'The Shadow Sister' for its blend of historical mystery and emotional depth, you might enjoy Lucinda Riley's other books in 'The Seven Sisters' series. Each novel explores a different sister's journey, weaving rich historical contexts with personal discovery. 'The Pearl Sister' and 'The Moon Sister' are particularly gripping, with lush settings and intricate family secrets. For a standalone with similar vibes, Kate Morton's 'The Forgotten Garden' is a gem. It’s got that dual timeline structure, where past and present collide in unexpected ways. The atmospheric writing and hidden family truths make it feel like Riley’s work, but with Morton’s signature Gothic touch. I couldn’t put it down!

Sisterland by Curtis Sittenfeld is this incredible blend of family drama, psychic abilities, and deep emotional exploration. If you loved that mix, you might enjoy 'The Immortalists' by Chloe Benjamin. It follows four siblings who visit a fortune teller as kids, and the novel unpacks how their lives unfold based on those predictions. The themes of destiny vs. choice hit similarly hard. Another great pick is 'The Vanishing Half' by Brit Bennett—twins, secrets, and the weight of identity, all wrapped in prose that feels like a gut punch in the best way. For something with a lighter touch but still packed with sisterly bonds, 'Big Little Lies' by Liane Moriarty has that same sharp, observational humor and layered relationships. Or if you’re after more supernatural intrigue, 'The Probable Future' by Alice Hoffman weaves magic into family legacy in a way that’s just as haunting and tender.

Black Water Sister' by Zen Cho is such a wild ride—mixing Malaysian folklore, family drama, and ghostly shenanigans. If you loved it, you might enjoy 'The Ghost Bride' by Yangsze Choo. It’s got that same rich cultural tapestry, blending Chinese-Malaysian traditions with a supernatural twist. The protagonist gets pulled into a ghostly marriage, and the world-building is just as immersive. Another great pick is 'Jade City' by Fonda Lee. While it’s more of a gangster epic with magic, the familial tensions and Asian-inspired setting hit similar notes. For something lighter but equally engaging, 'Dial A for Aunties' by Jesse Q. Sutanto is a hilarious romp with meddling relatives and accidental crimes—no ghosts, but the chaotic family energy is there.

I absolutely devoured 'Grey Sister' by Mark Lawrence, and if you're into gritty, character-driven fantasy with a dark edge, this is a must-read. The sequel to 'Red Sister,' it dives deeper into Nona Grey's journey at the Convent of Sweet Mercy, blending brutal combat training, political intrigue, and a dash of magic that feels both fresh and terrifying. What really hooked me was the way Lawrence balances Nona's personal growth with the larger stakes—every victory feels hard-won, and the world-building is immersive without being overwhelming. The relationships between the sisters are another highlight—full of rivalry, loyalty, and unexpected tenderness. The pacing is relentless, but it never sacrifices emotional depth. If you loved 'Red Sister,' this one cranks everything up to eleven. And if you're new to the series, trust me, it’s worth starting from book one just to experience the full impact of Nona’s story. The ending left me desperate for 'Holy Sister,' so consider that a warning!

Mark Lawrence's 'Grey Sister' is a gripping sequel that follows Nona Grey, a fierce and complex protagonist who steals the show with her raw determination. Nona isn't your typical hero—she's flawed, vulnerable, and utterly compelling. The book dives deeper into her past, her bond with the sisters of Sweet Mercy, and her struggle to control her dangerous abilities. What I love about Nona is how she balances brutality with loyalty; she’s not just a fighter but a girl who cares deeply for her friends. The way Lawrence writes her internal conflicts makes her feel incredibly real. If you’ve read 'Red Sister,' you’ll know Nona’s journey is far from easy. In 'Grey Sister,' she faces political intrigue, betrayal, and the weight of her own destiny. Her growth from a scared orphan to a warrior nun is chaotic and messy, which makes her so relatable. The book’s action scenes are breathtaking, but it’s Nona’s emotional depth that stays with you long after reading.

If you loved 'The Witch Haven' but want something with a darker, more mature vibe, there are definitely gems out there that hit similar notes. 'The Year of the Witching' by Alexis Henderson is a fantastic pick—it’s got that atmospheric witchcraft, a rebellious heroine, and a gothic setting, but with deeper themes of oppression and power. The prose is lush and haunting, perfect for readers who want more weight to their magical stories. Another one I adore is 'The Once and Future Witches' by Alix E. Harrow. It weaves historical feminism with witchcraft in a way that feels both epic and deeply personal. The sisterhood dynamic adds layers of emotion you don’t always get in YA. For something more surreal, 'Plain Bad Heroines' by Emily M. Danforth blends horror, sapphic romance, and meta-storytelling. It’s witty, eerie, and packed with queer vibes—think 'The Witch Haven' but with a sharper, adult-oriented edge. If you’re into dark academia, 'Bunny' by Mona Awad might scratch the itch; it’s wild, satirical, and full of twisted magic. Honestly, the adult witchy book scene is thriving right now, and these titles prove you don’t have to sacrifice that sense of wonder just because the protagonists are older.

If you loved the atmospheric tension and sibling dynamics in 'The Last Sister', you might adore 'The Family Upstairs' by Lisa Jewell. It's got this eerie, slow-burn mystery that creeps under your skin, and the way it unravels family secrets feels so satisfying. The book plays with multiple timelines, and the shifting perspectives keep you guessing until the very end. Another gem is 'The Roanoke Girls' by Amy Engel—dark, twisted, and dripping with Southern Gothic vibes. The way it explores toxic family bonds is hauntingly beautiful. If you're into psychological depth with a side of dread, these books will hit the spot. I still get chills thinking about that final twist in 'The Roanoke Girls'!

If you loved the gritty, morally complex world of 'Sister Night,' you might dive into 'The Library at Mount Char' by Scott Hawkins. It’s got that same blend of surreal horror and dark fantasy, with a group of adopted siblings raised by a mysterious, godlike figure—each mastering their own brutal 'catalog' of knowledge. The protagonist, Carolyn, has this eerie, relentless energy that reminds me of Sister Night’s determination, and the book’s violence is just as unflinching but weirdly poetic. Another wild card is 'The Devil in Silver' by Victor LaValle, which mixes psychological horror with institutional critique. It’s less supernatural than 'Sister Night,' but the way it traps characters in a nightmare they can’t escape—while still finding pockets of dark humor—feels spiritually similar. Plus, the protagonist’s struggle against forces bigger than himself has that same underdog thrill.

I got pulled into 'Sisters in Yellow' by the way it stitches a coming-of-age voice to a gritty, noir-ish Tokyo underworld, and if you liked that collision of tender memory with moral danger, there are a few books that hit similar notes. 'Sisters in Yellow' is narrated by a woman who revisits a toxic friendship and the criminal fringes of Tokyo; reviewers describe it as a noir-tinged exploration of female bonds, survival, and class that slowly unfolds past and present. For something that leans into Kawakami’s thematic territory, try 'Breasts and Eggs' — it’s by the same author and digs deep into womanhood, bodily politics, and the pressures of family and class in modern Japan, but in a quieter, more essayistic way that complements the raw, communal survival in 'Sisters in Yellow'. If you want another novel that centers complicated female friendships set against a pressure-cooker urban life, 'If I Had Your Face' follows four women in contemporary Seoul who assemble and betray one another while navigating beauty, work, and danger — it captures that same mix of intimacy and social critique. For a sharper psychological bite closer to pulp and obsession, 'Hooked' by Asako Yuzuki is a chilling look at loneliness and female relationships in modern Japan and scratches the slow-unraveling, thriller-adjacent itch you might have after 'Sisters in Yellow'. Finally, if the nightlife/hostess-club milieu and the way work shapes identity interested you, say yes to reading 'Convenience Store Woman' for an oddly humane, satirical counterpoint about survival through routine and 'Nightwork' by Anne Allison if you want nonfiction context on hostess culture that informs a lot of fiction set in Tokyo’s nights. I came away feeling like each of these titles extends parts of what fascinated me in 'Sisters in Yellow' — the bonds, the compromises, and that uneasy urban beauty.
