Portrait of a Witch Undone
Not yet published
Expected 25 Aug 26For fans of Starling House and A Discovery of Witches with a Thomas Crown Affair a contemporary New England coven hides the mysteries that lurk in the marshes north of Boston—and how they are connected to the largest unsolved art heist in modern history.
Once, Maeve Ryan was the strongest witch of her generation. But Maeve messed up a spell to contact the Lady of the Fens, an eerie Revenant who lures the unwary to their deaths in the brackish marshlands of the North Shore. Maeve destroyed her reputation, hurt her best friend Ash, and tainted herself with unbound, wild magic that transforms witches into insane Revenants.
With unbound power eating away at Maeve’s mind, all she wants is to get rid of her magic. Forever. But Ash’s research into how the spell went awry leads in an unexpected the Isabella Stewart Gardner Museum, and a link between the Lady and a decades-old art theft worth $500 million. When Ash disappears through a stolen painting’s empty frame, Maeve has to follow.
Inside is the Other Marsh, a haunting, deadly realm where only the Lady’s rules apply. Within this half-world lie secrets about North Shore’s history, Maeve’s failure, and the fate of the masterpieces that disappeared over three decades ago. But as Maeve fights toward the truth, she risks her friendship, her coven, and her life against enemies hiding in plain sight.

Part Piranesi, part witchy coven sisterhood story that will steal your heart. The marsh-filled museum is a crazy (read: CRAZY) setting that is its own strange character seeping throughout the pages of this book just as it seeps through the empty, stolen frames from the very real Gardner heist. Truly one of the most unique books I've read in a long time!
I was lucky the author let me read an early copy, and this checks all the boxes of my favorite kind of book: contemporary fantasy, biting prose, nature magic, action and adventure, stolen paintings, a dash of body horror? Shut up and take my money! If you loved The Once and Future Witches by Alix E. Harrow, or Ink Blood Sister Scribe by Emma Törzs, you won't want to miss K.S. Shay's debut.

The comps to Harrow and Kingfisher don’t lie, Shay is a *gorgeous* writer. I loved this book 🥹♥️

3.5 ⭐️ (rounded up) This was such a unique contemporary fantasy, centered around the 13 paintings stolen from the Isabella Stewart Gardner Museum in 1990. The way the author blends witches and magic into a real life unsolved heist felt seamless and incredibly original. I genuinely haven’t read anything quite like it before.
My one critique is that there were moments where I struggled to fully picture the scenery. The writing is gorgeous and very intricate, but at times it felt almost too intricate, and I found myself rereading a few paragraphs just to be sure I was following what was happening. That said, it’s still a beautifully written, thoughtfully crafted story, and I’m so grateful I had the chance to read an eARC of it.
Thank you so much to NetGalley and Erewhon for this eARC in exchange for my honest review!

Captivating world and character building that made for a book that I couldn’t put down.
It addressed some serious topics (namely loss, navigating relationships, decisions that aren't black and white) in a way that is digestible to adults or to teenagers/YA. The story felt fully fleshed out, incorporating real-world research about native people and covens. AND the (no spice) romance was catching and flowed with the plot.

Witches and art heists and the Power of Friendship!! Checked all my boxes. This novel had me on the edge of my seat, it was one of those rare ones that kept me up until 4am to finish it. I was thrilled to be able to read the early drafts and I’m so excited for everyone else to get to read it.

Can't wait for the release so I can relive the magic all over again! ✨ Thanks for kicking off my new obsession with art heists and the Gardner Museum. 💖

Maeve, granddaughter of the coven's matriarch and the presumptive successor, has been struggling with her magic since a spell gone wrong. She's becoming unbound—a threat to her coven and those she loves. Maeve has a plan to fix the problem, but things go awry when her best friend thinks she can bring great power to their coven and find the missing Isabella Stewart Gardner paintings as well.
I had fun reading this. I was incredibly interested in the story and I couldn't wait to find out what happened to all of our characters. The plot was incredibly unique, and I liked that there wasn't a ton of worldbuilding or explanation of how their magic worked in order to understand the story. The author did an excellent job creating characters that weren't necessarily good, bad, or "morally gray". They simply were human, with human emotions and desires. Nobody was written as a caricature character—everyone had nuance.
One of the issues I had while reading was the author introducing every. Single. Character. By race/ethnicity. "A white woman with a black hat...a white boy with floppy hair...a black girl my age...a white lady...a white guy..." I think this was the author's attempt at being inclusive, but it was very jolting and in a novel that required a lot of imagination to follow the plot, it felt like the author didn't want us to have any imagination when thinking about the characters. The first chapter of the book used incredibly vivid language, but that style of writing faded quickly and made way for some seriously lame character descriptions.
The second issue I had with the story was that it was a little difficult to follow at times. The plot was strong, but there were a lot of moving pieces. I thought to myself at one point, "This reads like the author knows exactly what's happening and the back story of every single character, but they're having a hard time clearly relaying information to us." I was still able to enjoy the book a lot, but this isn't a book to read in a place with a lot of distractions.

The concept of this novel was one of the most unique that I have seen in a while. It is a fun combination of historical fiction and fantasy. The story is based around the largest unsolved art heist in America at the Isabella Stewart Gardner museum in Boston, Massachusetts. While this story is fictional, it was very cool to involve a real life event so prominently in the story.
Our FMC , Maeve, is a disgraced witch from the North Shore witch coven, which is one of the many witch covens spread around the states. There was an incident last year with her best friend, Ash, and she refuses to practice magic to the disgrace of her family. One day, Ash thinks she made of discovery regarding the missing artwork from the museum leading her to be involved in a dangerous plot. With the help of Gabriel, an uncovened witch from another coven, Maeve embarks on a journey to save her.
The heist vibes were immaculate. I love how we had a group of people that did not fit together whatsoever initially come together to find a way to save their coven. I am a sucker for found family. The lore of the coven was also explained fairly well in a simplistic manner that was easy to follow. I thought the pacing was great as well with a great balance of action sequences.
The only thing that left a little to be desired was the romance. I never felt much a spark with the characters, and I feel as if it didn't add much to the story. It could've been entirely omitted and I still would gave enjoyed the story just the same.
Really enjoyable witchy story. Perfect to read in the fall months!
Thank you to Kensington Publishing and Netgalley for the E-arc in exchange for an honest review!! All thoughts are my own.

I received a copy of this from NetGalley.
I enjoyed this book, but at the same time, I struggled with it. I read it over the course of a week, flying through half of it in a single day and then finding it hard to push through the rest. I’m not sure if that was on me or the book itself. It’s definitely a unique story—the basic plot (though there’s nothing basic about it) centers on a witch, the granddaughter of the Coven’s matriarch, whose magic has recently started feeling wrong—“unbound,” as it’s called. Unbound magic is dangerous; it can transform you into a strange creature that feeds on magic, which is essentially the main “villain” of the story. There were plenty of elements I really liked, such as the incorporation of the real-world theft of paintings, which was an interesting touch, and the setting, which worked well. However, toward the end, when the action really picks up, it feels like there’s both too much information and not enough at the same time. This might be one of those books that benefits from a second read to fully take in all the details, but unfortunately, it’s not one I feel compelled to revisit

I received an ARC through netgalley.
I have mixed feelings about this book. I made it 108 pages in before deciding this book is not for me. I’m still not sure if it’s me or the book.
I really enjoyed the premise of the novel, somewhat modern day witch craft meets a real life art heist, and a missing best friend. There is a lot of unique world-building in this book that I haven’t seen before. That being said, I think there was a lot of information and not all of it was helpful to the reader. The writing, at times, seemed like a steam of consciousness, which caused confusion and boredom on my part. I noted based on other reviews that I am alone in this opinion. I really felt like I was forcing myself to get through the book and it failed to capture my interest.
So to end my review, I would say if the plot intrigues you, definitely give it a go! Witchcraft x Art Heist is really unique and I can see how others might enjoy this.
