The Jellyfish Problem

by Tessa Yang

A marine biologist makes the discovery of a lifetime when called to rescue the inhabitants of a small Maine island being menaced by a giant, glowing jellyfish in this richly imagined, wholly original debut.

Dr. Jo Ness prefers jellyfish to people. Her best friend, Aldo, was the exception, but he died seven months ago. So she spends her days hidden away at an underfunded aquarium with her specimens and a draft of the jellyfish guide she and Aldo had been working on together. His voice is alive in the notes in the margins, and it’s enough. Almost.

Until she receives a call from Nadia, one of the few other humans she’s loved but whom she hasn’t heard from in years, asking for her help. Nadia tells her a grand tale of a giant jellyfish terrorizing her tiny island off the coast of Maine and sends a grainy video of the creature. Frankly, the footage looks fake, but Jo drops everything to fly across the country to see Nadia again, and to find this supposed sea beast. She couldn’t save Aldo, but perhaps she can help Nadia.

But when Jo arrives on Shattering Point, Nadia is nowhere to be found, and the islanders she meets each have something different to say about the creature they’ve dubbed Clementine . . . a jellyfish who changes all who see it.

At turns an ode to classic sea monster stories and a vibrant tale of human connection, The Jellyfish Problem is an unforgettable debut that announces a new talent.

[Saray · Rating 4 out of 5]

I think a big reason new releases don't get good reviews is that they're marketed as a comparison of previously beloved books, such as the case with The Jellyfish Problem and Remarkably Bright Creatures. I've yet to read Remarkably Bright Creatures, so I have nothing to compare it to, but I thoroughly liked this book. I'm a lover of any marine animals, so the title of this really caught my eye.

The Jellyfish Problem starts with our fmc Jo, who receives a call from an old college friend about a mystical jellyfish near an island that's scaring the locals. Jo is a marine biologist whose life focus is jellyfish. She's currently in a state of grief due to the passing of her best friend, so when she receives the strange request to visit the remote island, she does not hesitate since it's a possible distraction for her.

The story is layered with so many elements. It's a mix of grief, horror, and mystery, scientific curiosity, and magic realism. Everything on the island is strange, and the author does a great job creating that atmosphere. It's not very action-packed, very tender and somewhat slow-paced, which I surprisingly enjoyed. I loved the way this was written, too. You can tell that Tessa Yang really did her research on marine life, but does not overcomplicate it. The story is a bit unusual, but so creative!

From what I can tell, the only similarity between this book and Remarkably Bright Creatures is that both books contain a marine animal focus. I definitely would recommend this book, but make sure to ignore any promotional stuff about the two books being similar.

After I heard the comparison of this to "remarkably bright creatures," I had to get my hands on a copy.

So many thanks to Berkley Publishing Group | Berkley for sending me this ARC. I AM SO EXCITED TO READ THIS ONE.

3.5 🌟

Tessa Yang’s novel is a beautiful dive into grief, connection, and the mysteries of the natural world. The story follows Dr. Jo Ness, a lonely jellyfish scientist, who is drawn to an isolated island by a glitchy video of a massive, mystical jellyfish sent by an old college friend she hasn’t spoken to in over a decade. After the death of her longtime friend and peer, Jo is just going through the motions, carrying guilt and unresolved grief. When her friend Nadia asks for her help with a jellyfish problem, Jo jumps at the chance to reconnect, but once she arrives, Nadia is nowhere to be found, and everyone in town acts odd and all over the place around her. It isn’t until she encounters the jellyfish, Clementine, that everything shifts, revealing that appearances are not always what they seem.

What I appreciated most was how the novel explored life, connection, and the emotional pulls that make us human. I really connected with the grief aspect of losing a close friend. While my experiences are not the same, I saw myself in Jo’s self-sabotaging behavior and the guilt she carried. I also loved the scientific elements. Coming from a biology background, it was a fun blast from the past, and the marine biology details, especially the subtle digs at sea turtles and sharks, were delightful. Yang’s perspective on jellyfish resonated deeply, and I found it fascinating to see her approach from a marine biologist’s lens, a viewpoint I haven’t encountered in fiction before.

I highly recommend this book to anyone who enjoys a gripping man versus nature story with emotional depth. Tessa Yang elevates the genre to something wholly unique, full of surprises and unpredictability. Beyond the adventure, the story touches on universal human experiences, grief, guilt, and connection, and emphasizes inclusivity in subtle but meaningful ways. It is a thoughtful, immersive read that lingers long after the last page.

The Jellyfish Problem is a fresh, imaginative take on sea-monster stories with heart. There is mystery, quirky characters, and real emotion as marine biologist Jo investigates the strange case of a giant glowing jellyfish. The writing is vivid and thoughtful, and the mix of humor, grief, and connection kept me hooked from start to finish. Highly recommend if you’re into something original and surprisingly moving!
Thanks to NetGallery for providing me with an ARC to review!

🌅 I was expecting a story similar to Remarkably Bright Creatures, and it really wasn't. This book completely surprised me. I went in expecting a quirky marine biology story and got something far deeper: it was part mystery, part quiet horror, part emotional unraveling of grief, all wrapped in an eerie, ocean-soaked atmosphere that I couldn’t shake.

We follow Jo, a marine biologist who prefers the predictability of jellyfish to the messiness of people. I liked that she was written as neurodivergent with social difficulties but still able to connect with a couple of individuals. However, she’s been barely functioning since the death of her best friend, carrying guilt that clings to her like a sock fresh from the dryer. When an old friend from college reaches out with a strange request, Jo doesn’t hesitate. The request? Come to a remote island off the New England coast to investigate an unusual jellyfish. It’s something to focus on. Something that isn’t grief.

But when she arrives, things are… off. The friend who called her is missing. The islanders are uneasy. And the jellyfish at the center of it all isn’t just unusual, it's mythical. To Jo, everything feels wrong. Too large. Too powerful. The jellyfish's appearance seems to be connected to everything happening on the island.

What unfolds is a layered story that moves between scientific curiosity, creeping dread, and emotional healing. I loved how the book blends grounded details about marine life with something much stranger. Each chapter opens with insights about jellyfish, which not only adds texture but subtly mirrors what Jo herself is going through as she struggles with her grief: fragility, survival, transformation.

This book shines in its atmosphere and themes. The coastal setting feels isolated and slightly unsettling, building tension without constant action. The emotional arc, especially Jo’s guilt and her struggle to reconnect with people, felt honest and grounded. I also appreciated how the story explores community, isolation, and the quiet ways people try to survive loss.

The pacing is definitely on the slower side, especially at the beginning, and it takes time for the story to fully reveal what’s going on. Some of the more surreal elements, particularly the deeper connection between the jellyfish and the events on the island, felt a little abstract and may not work for readers who prefer clear explanations.

The side characters also feel a bit distant at times, but that seems intentional, since we’re experiencing everything through Jo’s emotionally closed-off perspective.

Overall
I really liked this. It’s not a fast, plot-heavy thriller. It’s a reflective, slightly eerie story about grief, science, and the unknown. If you like books that blend literary fiction with a touch of the uncanny, this is absolutely worth picking up. I appreciate NetGalley and The Berkley Publishing Group providing me with this ARC in exchange for my unbiased opinion. And thank you to Tessa Yang for this fun fictional read.

[Mariah · Rating 5 out of 5]

Dive into the poetics of the ocean and the majestic royalty that lives below. One of the scariest things in our universe is the ocean due to its vastness and largely unexplored masses. So, how do we know if monstrous jellyfish are not already lurking on our coasts? We simply must hope! Or maybe the marine biologist in you may be enticed by this possibility. We always speculate on the unknown because it is up to our imagination to truly understand the concept of what may exist in the ocean. Jellyfish are beautiful creatures that are often overlooked – like the way society overlooks the many beauties around us and fears it instead.
The queerness of all is inclusive and really creates a narrative that is for everyone. More horror that flows so naturally to remind you that we exist as real people too. And then there is Clementine - who will challenge your perspective – so take a swim for this one. Maine was the perfect setting because think of all the unexplored ocean there. If you have ever been to Maine for even a vacation it will make sense. This is also a story about how we isolate ourselves in moments of grief and take any excuse to find ourselves through this isolation.
This is a horror that is exploring the human psyche through narrative. Exploring the why behind our motives. Grief can be both motivating and debilitating. What does Clementine metaphorize? These are the type of questions that Tess Yang so delicately weaves into her writing. I devoured this narrative in a day nearly wishing for more. There is so much to learn about the ways of the jellyfish that translate to a nuanced horror. Horror is inherently a nuanced genre that if you are here – you have learned to appreciate the taste for.
Finally, this is a discovery narrative. We are looking for the living in everything we digest. So why not look deeper into the mysteries of the jellyfish? What does Aldo leave behind that truly show us the desires of the human condition versus the motivations of the sea. There is so much to unravel as the mysteries of the deep become clearer as they surface. It is the surface that truly throws a tidal wave of insecurities our way. Thank you Tess Yang, Netgalley ,and Berkley Publishing Group for this advanced digital copy. All opinions are my own.

I was so excited to read this as I had just finished Remarkably Bright Creatures and read that the vibes of this were similar. Whoever said that was WRONG. The only comparison to be made here was that each book had an invertebrate oceanic animal.

I love ocean creatures especially jellies so I was pumped to read this. It started off great, was really getting into it. But then it got weird, and then it got far fetched, and then there was some weird fantasy and folklore element that didn’t really work here. I loved the concept of the unidentified jellyfish causing havoc on this island and the scientists have to figure out a way to stop it. However, without spoiling the book, the reasons and the way it was terrorizing the town, wasn’t what you expected.

None of the characters were that memorable. They were just boring and not very likeable. Ultimately, I felt like nothing really happened throughout the book. I didn’t really understand why Roger was the chosen one (vague to prevent spoilers). I think Nadia would have been a better choice and would have brought the overall drama and emotion of the book up a level. I found there was more brainstorming than actual presentation of the plot. So many ideas that just didn’t get portrayed well enough.

I did enjoy the little blurbs at the beginning of each chapter. They were little snippets of the book Jo and Aldo were working on together. However, it wasn’t clear that’s what it was and the little text communication between them referring to their book thoughts. The formatting was bizarre there and needs some differentiation for the final copy. It wasn’t very clear that it was a text thread. I changed all my kindle settings trying to fix it until a third of the way in, when I clued in. I think the cover is very pretty and one of the reasons I was drawn to reading.

I was pretty disappointed in this book and really had to force myself to finish it as I had an ARC. It’s alright if you’re looking for a book with minimal stimulation. But I found it quite boring.

Jo, a jellyfish scientist, is called out of the blue by a decade old connection to an island off of Maine to investigate a strange jelly phenomenon. The mysteries on the island get tangled with Jo's internal battles and it seems like both problems will need to be solved if she has any chance of making it out alive.

I liked the supernatural and sci-fi elements that were woven in the novel and how it was juxtaposed with chapter headings about jellyfish facts. The jellyfish facts were part of a book Jo and Aldo were writing together and the sidebar comments they added really brought the two characters to life. The jellyfish problem on Shattering was looking to be so inexplicable, I was really happy that the final explanation fit in the realm of real life jellyfish behavior.

This book had a lot going on and played with a ton of different genres. From thriller to horror to romance to magical realism to comedy to sci-fi, Yang throws it all at us and nails each mood when we are in that moment. As a whole though, genre switching this much was a bit overwhelming and felt distracting to the main storyline. The pace of the novel slows exponentially in the middle as we wait a month for another full moon/jellyfish reappearance. Jo fills this time by working on herself and fulfilling side quests from other characters. It was strange to spend so much page time in this 30 day waiting period and then almost no time at all on what happens on the island once a solution is discovered.

And finally, I don't think domestic abuse should be written about lightly or used for comedic relief and this book unfortunately leans heavily on that approach. There are no repercussions to the destruction and harm we are shown and it feels like this was a missed opportunity to comment on who the real villains in our world are.

Thank you to Berkley Publishing Group for this gifted ARC!

This was such a unique and interesting book. I absolutely loved the plot, the mystery, the little touches of romance we got were really sweet as well. It was just overall an amazing and captivating time. This was more than a book on a giant mysterious jellyfish, it was about loss and grief and community. It was amazing, and I loved the New England backdrop. I'm from Maine/New Hampshire and this was just really nice to read of some familiar places.

Jo is a fantastic main character, and I related to her quite a bit. She's a bit awkward in intimate situations, she doubts herself somewhat when she is dealing with people and she prefers creatures to people most of the time. She is dealing with the loss of a very important person in her life and she blames herself for his death. This book is really heavy on dealing with grief and trying to find some closure. I felt for her so much, I understand grief and it's heaviness and what it takes to get through some tough days of dealing with it and this demonstrates it really well.

The jellyfish aspects of the book were phenomenal. It honestly makes me want to do a ton of deep dive research on jellyfish and learn even more about them. Each chapter beginning has jellyfish facts and it was so cool. I was not only excited to read to continue the plot, but also excited to continue to get to more jellyfish information. It was so incredibly cool.

If you enjoy a story on dealing with grief and loss and how important community can be, definitely give this a read. Bonus if you're into learning about sea life, that aspect was just really fun and exciting to read. This comes out June 2nd!

This was a different book. It seemed to be realistic fiction and as you got deeper into the story you realized there was a huge fantasy component to it. Jo Ness is a marine biologist specializing in jellyfish. She is not a social person. She has worked for years for a small aquarium that is basically a dead-end job, but it allows her to research and write a tome on jellyfish. She also lost her best friend Aldo a number of months ago (in a scuba accident she feels responsible for) and now she is surviving and going through the motions of life. Out of the blue she is called by Nadia, one of her few friends who unfortunately dropped out of her life ten years previously. Jo is immediately drawn in as she has mourned the loss of Nadia all these years.
Nadia has had many jobs, but she now lives on Shattering Point, a small island off the coast of Maine. She sends Jo a picture of a huge jellyfish and wants her help and expertise. Jo drops everything (which is not difficult as she has felt she has no life anyway) and travels to Maine. Once she gets to Shattering Point, she finds out that Nadia is not there. There is so much going on that Jo is not aware of and it turns out that is a bad thing, and it gets worse.
In some ways this was a hard book to get into. It takes a while for the story of Jo and Aldo to come out and what is happening on Shattering Point adds to the confusion. I would give it 3 stars except the book did pull you in and I enjoyed the ending.

Every once in a while a book comes along that restores my hope and heals my heart especially at a time in our country that feels so hopeless. Theo of Golden was one and The Jellyfish Problem is another. It’s the story of a giant jellyfish. Kind of. It’s definitely a story of people and a community that is struggling to survive an untenable situation. Jo Ness is a scientist who studies jellyfish. In fact she’s obsessed with them. But she has also recently lost her best friend and has been overcome with grief, self blame, and a new terror of the waters she loves. When a long lost friend sends her a video of what looks like a giant jellyfish she runs to help even though she really believes it’s a hoax. She also wants to reconnect with this friend that she loves and regrets losing. What she finds on Shattering Island leaves her stunned and eager to help while doubting her ability to do so. The story is one of overcoming grief and self doubt, relying on a community of people for strength when the preference is to go things alone and finally finding joy and love and self renewal after loss. The book is also dispersed with lots of wonderful information about jellyfish and I really learned a lot. I was on an international flight home that suffered a great many glitches and snags and a mad dash through an airport to make a connection that left me in tears. I read this book and it truly uplifted my spirit. I recommend it to everyone

[Melissa Chapman · Rating 3 out of 5]

This book feels hard to rate. Jo is an autistic coded FMC, who turned her obsession with jellyfish into a career. I loved that she found a job she was happy in that allowed her the freedom to study and research jellyfish.
This is a story about grief, acceptance and moving on as much as it is about a mystery jellyfish trapping an island.
Jo learning how to deal with the recent loss of her best friend, and facing the reality that her former best friend in college never felt what she did is hard for her.
The story gets pretty mystical and magical - and while I do love the bits with Aldo's ghost (and the back and forth comments on the paper that are writing), the connection to the jellyfiah and effects it had were eyebrow raising and a little baffling.
It's definitely got a slow and steady feel to the writing, and while I liked Jo and Tony, I found the rest of the Islanders a little flat as Jo herself never allowed much of a connection. Even Margo who I loved, didn't contain much substance as Jo was always rushing away from her.

Overall I liked the story, and it was a very different kind of book. There is a lot of mystery surrounding the Jellyfish and the island, and while there is no animal voice, there is a deep connection between the creature and the humans.

Thank you to Netgalley and the publisher for the ARC. Opinions are my own.

Like many others, I loved Remarkably Bright Creatures and hoped this novel would offer a similar experience. Sadly, it fell short of those expectations.

Jo Ness is a marine biologist summoned to a small island off the Maine coast to investigate what appears to be an unknown species of jellyfish. She arrives burdened by two painful pasts: a brief relationship with Nadia that ended eleven years ago, and the recent loss of her colleague Aldo, for whose death she feels responsible. Shatterling Island itself is richly populated with memorable characters, most notably Tony, who becomes central to Jo's time there. A line of Tony's struck me as the novel's most fitting epigraph: "Things die, Jo, she said quietly, so that others can live."

I enjoyed the short quotes opening each chapter, and particularly loved the exchanges between Jo and Aldo that followed them — these felt true to both characters and were among the book's highlights. Unfortunately, they weren't enough to elevate the novel as a whole. The story carries too many subplots, each competing for attention without fully earning it, and the frequent use of scientific nomenclature felt more distracting than immersive.

A disappointing read, though not without its moments.

3.5 stars. THE JELLYFISH PROBLEM follows Jo, a jellyfish expert who travels to a remote island off the coast of Maine to research a jellyfish the size of a sea monster at the request of an old friend from college, Nadia. The story then takes a turn when Nadia disappears shortly before Jo’s arrival, and the townspeople won’t share what they know about this jellyfish.

Throughout the story are many undercurrents. Jo is anguished over the unexpected loss of her best friend and writing partner, Aldo. Jo also struggles with the inability to connect with others.

THE JELLYFISH PROBLEM has an underlying LGBT theme. Jo had a brief fling with Nadia, one of the key drivers for her dropping everything to visit the island where Nadia resides. She’s also attracted to Tony (interestingly, not spelled Toni), the niece of the B&B owner where Jo is staying.

Overall, I enjoyed the story, especially the cleverness of the ending.

This book would be a great read for anyone who wants to stray beyond standard adult fiction but isn't quite ready to dive into a full fantasy or sci-fi book. Can we call this modern fantasy lite? I do love a good fantastical element, especially when believed by a whole community. It's so much more fun when you have a real problem to solve, rather than have "convincing people that something is real" as the main crux of your story.

I didn't connect very well with the characters. Some of them felt flat or unnecessary. That said, I liked the main character and how her friendship with Aldo was slowly revealed. The exploration of grief and identity and relationships would be appealing to adult fiction readers.

I received an ARC of this book via NetGalley for an honest review.
I absolutely loved this book, I devoured it over three days. I love Jo, and her love for jellyfishes. This book wasn't what I expected, it was so much more. This book was full of found family, reconnecting, recognizing friendship and love, and a bit of intrigue too. Clementine, the jellyfish, was a great character too. I loved how Jo and the others on the island fared with having this massive jellyfish to them, and the mystery surrounding Clementine's presence and more. It was an absolutely beautiful book. It took me about 25% of the book to realize what the first part of each chapter was (a snippet from the book Jo was writing on jellyfishes) - but once I did it was a unique added addition. Anyhow this book was lovely, I really enjoyed it!

This was such a beautiful and mysterious story! I did not want to put this one down! Each chapter began with a short excerpt from the main characters book on jellyfish and I thought that was so clever.

Jo Ness receives a call from a long ago friend who wants Jo to come and check out the jellyfish problem they are having on the tiny island she is living on, but when Jo arrives, Nadia is nowhere to be found and she starts to worry that something bad has happened to her. The story turns into yet another problem when Jo finally learns the real reason she’s been called to the island. Will she solve the jellyfish problem and save the people?

This was so clever and I just loved how much this story reminded me of Remarkably Bright Creatures. I will be reading Tessa Yang again!

A sincere thank you to Netgalley for this ARC!

This is one of the best books that I've read in a long time. It is very clear that the author spent an exorbitant amount of time researching jellyfish, Marine biology, and ocean sciences in general.

The book was intelligently written, there were hints of Mystery and Thriller, and it wraps up very nicely at the end. The author believes in the intelligence and capabilities of her readers and does an excellent job of "show and don't tell".

Its exploration of the power of grief, and the process of healing from loss, was incredibly touching. I teared up more than once.

Though this is not the kind of book I would normally pick up, I will highly recommend it to anyone who enjoys quality writing and an emotional story. The mystery kept me turning pages until the very end.

I look forward to reading other works by Tessa Yang.

4 stars because 3 felt too harsh.

I'll keep this short and sweet. If you are into books that feature scientists using their knowledge in a race against the clock for survival, this book will do it for you. If you enjoy books that are full of a sense of discovery and awe, this is the one for you. Finally, if you enjoy your books most when characters are forced to unpack their grief via the main events of the story, then this is the one for you.

The Jellyfish Problem is very fun, it mixes magical realism really well with lit fic pretty well, with some genuine horror moments strewn throughout. Genuinely, there were a few moments in this book that were bone chilling. I'm not sure if that was the express intention but that is absolutely how it came across to me.

Marine biologist Josephine Ness has had a difficult time connecting with people, and after the recent loss of her best (and maybe only) friend, Aldo, it’s become increasingly difficult for her to finish the book they’ve been working on together. When Jo gets a call from the only other friend she’s really ever had about a mysterious creature bothering the residents of a remote island off the coast of Maine, Jo goes to see the creature, and maybe repair the relationship with her former friend.

What Jo finds defies her expectations, both of the jellyfish she has spent her life studying and her understanding of humans. A beautiful tale of the interconnectedness of all life, and the beauty we can find when we try to understand one another despite our differences.

If you are picking this book up because of the comparisons to Remarkable Bright Creatures, do not. Insofar as it features a soft-bodied marine invertebrate, they are comparable. However, if you’re expecting the heart and connection with the characters that the comparison evokes, you will be exceedingly disappointed.

Personally, I do not enjoy passive books where nothing happens, unless the characters are extremely strong. Consequently, I did not enjoy this book, although I forced myself to finish it out of respect for the opportunity to have been given an ARC. I wish it weren’t the case because it did sound very intriguing to me. I think the marketing simply oversold the actual product.

My experience reading this one: I texted a friend 25% in, “I think this is one you might like.” Then about halfway through, the text became, “This may have taken a turn that I am NOT into… I’ll keep you posted.” And…. I haven’t updated her yet because I’m still a little unsure. It definitely didn’t go fully off the rails like I was scared it might. Part of me loved it. Part of me was like, no this is too far-fetched. It’s definitely kept me thinking about it! (As a caution: I don’t really think the comparisons to Remarkably Bright Creatures are warranted).

In The Jellyfish Problem we follow Josephine 'Jo' Ness, a marine biologist with an expertise in jellyfish as she mourns the loss of her best friend, and is haunted by the return of another old friend from the past weaving an enticing tale of a gigantic jellyfish off the coast of Maine.

The story is one of loss, rebirth, navigating grief and managing new friends and old. The writing was excellent, and I particularly enjoyed the fact each chapter started with an excerpt from Jo and Aldo's book, including footnotes and commentary. A recommendation for anyone who is fan of the deep sea, stories of personal growth, and those haunted by the power of nature.

Dang. This book was fascinating. It was part character growth (and dealing with grief) part fantasy/magical realism. I never knew that I would learn so much about jellyfish. I don't know if I was supposed to love Shattering but I certainly did. I might even risk Clementine's connection just to be able to enjoy that island.
Editor note: Because this was an ARC, there were some formatting issues especially around the notes from Aldo/Jo at the beginning of each chapter. It actually took me a while to even understand what those were due to the editing issues.

While I have a few issues with this book, ultimately, I did enjoy it. It wasn’t anything like my normal reads but all things considered, this was an interesting read.

Delightful book. Josephine, who is a marine biologist specializing in jellyfish, receives a call from a college girlfriend who she hasn’t heard from in over 10 years.

Magical realism gone wrong....the concept of a "monstrous" jellyfish possibly terrorizing a remote island had the potential to be an engaging "horror" read. I DID finish but forced myself to. I found the main characters were not likable. TY NetGalley for the arc.

[Jeremy Garber · Rating 3 out of 5]

I was provided an advanced readers' copy of this novel by NetGalley, and I think they did the book a disservice. The promotional materials promised a book for those who enjoyed Remarkably Bright Creatures (which I did) - but that novel isn't this novel very much at all. (Apart from dealing with sea creatures, that is). I would describe The Jellyfish Problem as a sort of grim magical realism. Josephine Ness is a marine biologist stifling in her underfunded aquarium and grinding for the third year through a book she was co-authoring with her dead mentor and friend. A college friend calls her unexpectedly with an invitation to investigate a new and startling kind of jellyfish. Josephine arrives - only to find out that the jellyfish is not only unique but powerful and potentially deadly.

Yang blends a tale of personal academic growth with Japanese folklore, blurring the lines between scientific inquiry and a touch of subtle, growing horror. As she investigates the jellyfish and the small group of people on the northeastern island that harbor it, Josephine must deal with her ancestors, her former lovers, her ailing career, and her own sense of self. An eminently appropriate beach read - but don't expect to be cozy while you're figuring out what's going on.
