The Oldest Bitch Alive

by Morgan Day

For fans of Sigrid Nunez’s The Friend and Nicholson Baker’s The Mezzanine, a polyphonic debut following an aging French bulldog and the parasitic worms that send her toward death — a singular, sly novel about form, freedom, interiors, and the matter by which we are composed and consumed.

Gelsomina is an elderly French bulldog who lives in a glass house in the mountains. Paned by transparency, she’s lived in imitations—of the man and the woman, of the younger dog, Zampanò, of the wild unknown beyond the windows. 
    One day, Gelsomina accidentally ingests an orb of parasitic worms. Approaching death, and filled with new life, she begins to see everything differently. She makes changes in the pattern of her days, and the glass house fractures into many voices. The worms burrowing into Gelsomina regard her body as an imperfect structure, the home they inherited but did not dream of. The couple—Wendy, in interiors, and John, in architectural design—face the claws of human attachment, and what our will to domesticate means for the life of an animal who can see the wild, but never know it. 
    Day’s architectural instincts breath into Gelsomina’s new and panting life meditations on animal suicide, string theory, philosophical approaches to form, and the question of whether a glass house can ever be a home. The Oldest Bitch Alive tails Gelsomina into one final, ecstatic sprint through the invisible fence and into a wilderness she’s never seen—activating the depths of attachment, reverence, death, and the bounded self in dichromatic color.

Oh, Gelsomina, you broke my heart. I don’t know what Astra has started doing — first Fátima Velez’s Galapagos, now this — but please keep going, and I’ll keep raving about your books!

Morgan Day has written an unclassifiable novel about animals, humans, and the spaces they (do not) inhabit. Day somehow manages to invent a wholly new syntax for thinking about what/who/where — and in what/in who/in ???. I’m not being intentionally obtuse, but how else can one describe philosophizing worms who accidentally end up inside a dying dog in a glass house with two humans who…

Interiorities and exteriorities get properly muddled here — and what a glorious muddle it is.

I thought this was the best contemporary novel I’ve read in a while — I was moved, entertained, impressed, grossed out, titillated, comforted, and ultimately grateful. The writing style shifts around but I liked it all. I cried twice. Beautiful and inventive meditation on mortality and Being. I’m gonna read it again.

[John Caleb Grenn · Rating 5 out of 5]

In which I try to tell you just why this book is so good.

This book is so full of clear-eyed evidence of the author’s deeply considered philosophy of personhood, doghood, wormhood: the state of being alive and holding some form of consciousness, selfness. A study in being. It’s deeply considered in the way it’s expertly rendered so sensitively and whimsically across these pages—sort of along the lines of “you don’t know something well enough if you cannot teach it to a child,” this has that same sort of innate depth across paradox-full pages of somber whimsy and detached empathy.

It’s rich in complexity, but comes across like it’s fun.

The feeling of every single emotion here sends echoes through the mind—the sort of prose that makes you feel the meaning of the sentences in your stomach, in your mind, and from a strange distance as well.

I’m amazed at this creation. Day takes traditional concepts of metaphor, expands and elaborates and creates a whole new space for the device to do work. I’m stunned at the clarity with which she translated her ideas here onto the page.

I had this thought along the way: this book should have never worked.. But that isn’t true. It’s not. Truth *always* works. This book was always going to work! Not to minimize the gargantuan effort this novel must have taken, but this novel feels completely inevitable.

For the reader—it takes time, it takes patience, and I’m not trying to like puff myself up in some stupid way here, but I’ll just say it plain: I think it takes a developed, darkened, wizened sense of humor and empathy to appreciate this book at the level it deserves. I hope I did it justice. It’s not a breezy existential crisis this Frenchie is having, is what I’m saying. You’ve got Donna Haraway quotes about Metaplasm in here, y’all. It’s so much more.

I know so many people who will be excellent readers for this book when it finds its way to them. For me, it was sort of the ultimate “ENFP” reader sort of book. “Omg it’s about an old dog that gets worms and has an existential crisis haha, sounds SOOO fun, anyway LETS GET DEEP AND SERIOUS NOW OKAY.” I think this is actually for people who like Cărtărescu and Belben and Knausgaard. This book reads like a rediscovered cult classic from the 70s. There’s absolutely no reason Morgan Day should not enter both the summer beach read and the regular litbro circuit with this winding, spiralling, morally and ethically and philosophically curious speculative novel about a dog having a worm crisis. I loved it.

I love the idea of this, but the writing style is not for me. It feels a tad too overwritten and ultimately is not keeping my interest.

Thank you to Astra House for the ARC.

thanks to netgalley and astra publishing house for an arc of this title! morgan day's debut has proven to be one of the weirdest, most original works of literary fiction i've ever read in my life. the perspectives shifting from gelsomina, to her worms, to the goings-on of the glass house, all were stellar and completely unique in their narrative voice. i had no clue where this story was going, but it definitely wasn't i expected. so incredibly unusual in the best way. i can't wait for more from this author!

In my top 3 “Biggest Book Letdowns”. This is the book equivalent to clickbait: striking title, curious premise, charming cover, that all fall for not into a spiral of overwritten “look how smart I am and how many words I know” tedium.

[Ann (Inky Labyrinth) · Rating 3 out of 5]

Parasitic worms trigger an existential crisis in an old French bulldog. What does it mean to know yourself? What about to know the other you? If you split in two, is that new you, you too? Explorations of extreme isolation and loneliness and what it means to be alive as a creature amongst creatures on planet Earth. Also, orbs.

Reading it felt like I had to hold my head underwater to listen to what was being said, and it was challenging, but it was worth drowning for.

Thank you Astra House for the review copy.

in reading this book i have learnt lots about the world and about myself - that prose can be so full of joy in an inherent way that makes it tremendously difficult for fatalism and nihilism to persist in my life, that there is delight to be found in reading about dogs, that existentialism is not just for people, and that i read more books about worms than i think i do.

i read the first half of this book in a cafe in seattle with dan and it was so much fun; this book has boundless amounts of whimsy and happiness and at the same time angst and tension. day balances this in a fascinating way which ceases the undercurrent of unease from feeling overwhelming and provides degrees of affection and special-ness to the mundanity of life. the premise of this book is absolutely ridiculous but from page one i was in love with gelsomina!!! how not to be. the two stupid worms too - absolutely beautiful. the prose was lyrical and momentous and alive in a way that was quite a spectacle to behold, and it always felt joyful; i can't think of a better word.

where i think the book fell short for me was the last few chapters or so; i started getting a little lost and the writing got a little too ramble-y for me to feel really convinced by the closure or lack there-of afforded by the ending bit, which is a shame because truly the rest of this book is so incredibly strong as an effort. even with this less-than-ideal ending i on the whole liked the book so much that i was tempted to give it five stars.

aside from that, the characterisation was so well done too. the little quirks of gelsomina, the distinct philosophical attitudes adopted by the worms. brilliant! i think this was a book that was very me, for lack of better phrasing. its weird, its well-written, and for the most part (other than getting confused) i really enjoyed my time with this story and with these characters. if this helps to compel anyone to pick this book up, this reminded me a lot of alysa liu iceskating (a big compliment).

A simple premise of a French bulldog as a pet and her life in a glass forward house with a couple, after she is infected with parasites. However Day zooms in and explodes this sliver of the world, giving voice to said bulldog, and the parasites inside her. Best - and weirdest - novel I have read in a while! Also the best novelistic take on stuff going on in feminist scholarship like Donna Haraway, Karan Barad etc!! Want to teach this book to some geography nerds soon as possible. Day is an architecture critic who is very interested in issues of the more-than-human - basically she rocks ..

[Nicole · Rating 5 out of 5]

One of the most enjoyable literary fiction books I've read in years. You really need to relax into the absurdity and approach the book like a poem or a song.

Morgan Day had me deeply invested in the lives of parasitic, philosophizing worms and her beautiful prose made me look at my life differently.

I am still contemplating who owns whom - the body, the parasites inside, the people, the glass house? All of it? None of it?

I do not know who I could recommend this to or even give this to - it's kind of a big ask of a book but incredibly worth the effort.

My only minor quibble is with the last few pages; it gets extremely trippy and didn't feel as sharply written.

Over all a stunning book and one I will return to.

Not for me. Severely overwritten and full of itself.

[Andi_loves_2_read · Rating 5 out of 5]

Wow. What a ride! I’m going to have trouble describing this book and what I loved about it - but those are the best kind of books for me.
We hear mostly from Gelsomina, a French Bull dog, who is nearing the end of her life and has ingested worms. We also hear from the worm(s) who now live inside Gelsomina. The point of views of Gelsomina and her worms are so clever and unlike anything I’ve read before.
I recommend this book to readers who enjoy philosophical reads and also those who enjoy the quirkiness that is obvious in a book like this. I was pleasantly surprised and would definitely read whatever Morgan Day puts out next!

ARC from Astra House. Gorgeous debut and truly would have given it 5 full stars for the phenomenal journey it takes you on except that the last 30 pages felt like reading some truly deranged hallucinated paper I would have written, stoned, in a philosophy class at 19 years old. I should have just bowed out before then because I was really so blown away by the book's success in making me genuinely care about the survival of the worms and the real tenderness that we feel for a fucking French Bulldog. Ending the book in this unbearable way actually feels like punishment for genuinely enjoying a book about worms. You got me!

I know this is certainly not a book for everyone, but with more thoughtful, character-driven ending that capitalizes on the incredible emotional velocity of Gelsomina and her owner's realizations that she is dying, I would have 100% stood solidly behind it. It's undefinable, all-consuming, and unbelievably sensitive to the interiorities of small things. Day is clearly a strong new voice, the way she writes the corporeal moments are wildly successful here, her editors needed to take a fine-toothed comb to the "philosophy."

Disregarding the last act, deserves to stand on the shelf next to PURE COLOUR by Sheila Heti or Ling Ma’s short stories

What a bizarre world that Day crafts within this novel!

This book does not give you a moment to catch your breath; it is unabashedly weird and absurd from the very first pages. I found the narrative choices in the novel to be incredibly bold, and sometimes even off-putting, but overall well-chosen. Day's writing is enticingly strange, managing to feel both dreamy and uncanny at the same time.

The world is also beautifully fleshed out, with a full and atmospheric setting that switches between mirroring and executing the stifling limitedness of Gelsomina's life. I also found myself impressed by Day's ability to capture how lonely it is to simply exist sometimes. Although there is definitely a lot happening in this novel, how alone we are in this world was a sentiment that was showcased in a meaningful way throughout the story.

Obviously, with bold strokes, there are bound to be flaws. While the majority of this book surprised me or had me anxious to find out what was going to happen, I still had critiques. The first was that I spent a fair bit of time just confused about what perspective we were taking, where exactly we were in the timeline, or if what was happening was real or not. However, my main criticism of the novel lies in the ending, which I think had the potential to wrap the story up satisfyingly and interestingly, but did not manage to completely achieve it. Although I loved the very end of the novel, the lead-up was too muddled and disjointed for it to feel like it really stuck the landing for me.

However, I did find myself really enjoying this novel, and I was incredibly impressed to discover it was a debut. I look forward to seeing what else this author writes. For all the freaks (or philosophy majors) in your life, have them try this one out.

Thank you to NetGalley and Astra Publishing House for the arc.

[eve is reading · Rating 1 out of 5]

in a bizarre turn of events i have now read two books from the perspective of worms. i really disliked both books. it is not because of the gross and slimy way the parasites describe themselves and their surroundings. it is just that this isn't very interesting to me. it is totally weird and should be thought provoking as there is plenty of existential thoughts flowing from both the worms and the dog- but i found this exploration unenjoyable and therefore ultimately pointless for me. the writing felt like it was excessive in trying to be profound, when things could have still gone into this territory without being as obnoxious sounding. if you like weird books, give it a go! it was worth a try for me though it ended up a disappointment.

Received through edelweiss+
A perfect blend of absurdity and philosophical musing, this novel takes on the perspectives of Gelsomina, an elderly French Bulldog, and the worms that are killing her. Controlled from the outside by the confines of her owners and now from the inside, Gelsomina provides us with beautiful meditations on autonomy, love, and the meaning of life. There is a stark contrast created by the pairing of heavy introspective text with base desire and the simple reality of existing that serves to better carry these complex themes, and it carries them well. The nauseating intimacy of parasitism is not to be forgotten and can even be found in the most surprising of places, like reflections on the glass house Gelsomina lives in. I find it almost hard to believe this is a debut novel and am ecstatic to see experimental works like these published.

[Elizabeth G · Rating 4 out of 5]

Day delivers a debut of astonishing ambition and genuine originality. The polyphonic structure, voices of dog, worms, and humans intertwining, could have collapsed into gimmickry but instead achieves something profound: a meditation on consciousness, domestication, and mortality that feels earned rather than imposed. Gelsomina's glass house becomes a metaphor for all bounded existence, her final sprint through the invisible fence both ecstatic and heartbreaking. The architectural precision, the sly humor, the unflinching gaze at what consumes us and what we consume, all signal a writer of serious gifts. Comparisons to Nunez and Baker are justified but Day's voice is distinctly her own. A singular, unsettling, beautiful novel about what it means to be alive inside a body that will fail.

[Kimberly · Rating 3 out of 5]

A book told from the perspective of a dying dog and the parasitic worms that are killing her.

I’ve never read anything like this. I enjoyed it at parts when it was really about the dog or the worms. The author has an architectural background and that is reflected in what felt like tangents about the house and the owners. I was much more interested in the dog and worms. I found their perspective was portrayed with rich prose and I appreciated the humor in the book.

This is a book that is going to work for some people and possibly frustrate others. I would recommend giving it a try, if for no other reason than the unique premise.

Thank you to Astra House for the ARC in exchange for an honest review.

An elderly French bulldog named Gelsomina, who lives in a glass house with her owners and their other French bulldog, ingests an orb of worms and starts seeing the world in a philosophical way.

I fear I do not have the literary chops to properly appreciate this novel. It was incredibly out there, and genre-defying which I admired, and there was a rhythm to the prose that I liked. However I struggled with it as a reading experience as I didn't really get it.

A very baffling book that wasn't for me, but there was something about Gelsomina and her little world that intrigued me, so three stars it is.

[Jimmie Kirby · Rating 5 out of 5]

told from the perspective of a dog who’s ingested parasites - and the worms living inside her? i was hooked instantly. there’s heart, there’s science and history, and there are plenty of “what the hell am i reading” moments (in the best way).

this book is delightfully weird - sharp, funny, and surprisingly tender. the alternating perspectives between the dog and the parasites were done so well. as a dog owner, it definitely unlocked a new fear; as a reader, it unlocked an entirely new world. i loved every bit of it.

the fact that this is a debut? unreal.

[Ally · Rating 3 out of 5]

Definitely one of the more unique books I've read.
You get perspective from both the dog and the parasites living inside the dog... Bizarre to say the least.

Love it or hate it, it's definitely bold and refreshing, but honestly, it didn't always click with me. If you're in the right headspace for it, it's pretty intriguing, but it's definitely not for everyone. Still, I was curious enough to keep reading and see where it'd go.

Thank you NetGalley & Astra Publishing House for the ARC!

What a deeply bizarre and philosophical book.

When I heard this was a weird story about an old French bulldog with worms from Astra House, I was so excited! And while I deeply enjoyed parts, some of the tangents left me bored.

Admittedly, I was not ready for how philosophical this book would be. The explorations of self, the meaning of life and death, and reproduction are thorough. I wish this story leaned into the humour a bit further, because those are the parts that pulled me in to the message the most.

If reading, get ready to hear about:”({i})”

[Olga · Rating 5 out of 5]

This novel is an experience unlike any other. It is not only a moving story about a cute French Bulldog, but a very nuanced take on beings' existence (and the existence of objects), consciousness, who we are and what it means to be alive. It is not only an examination of Gelsomina or the worms - but all of us.
It was definitely a challenging read, but the intricate vocabulary and prose forces you to pause and contemplate. And you need to with a book of this magnitude.
Unreal writing. Highly, highly recommend.

[Torie · Rating 3 out of 5]

I have a soft spot for books narrated by animals in existential crisis, and Gelsomina makes for an interesting protagonist. An aging French bulldog infested with parasitic worms philosophizing about the existence of a true self, the charade of how she is perceived, and the true meaning of life. Liked it, but went on too long for me; The prose choices wore me out after the first hundred or so pages, with how stylized and abstract it is.

[M.Regier · Rating 1 out of 5]

Meh. Interesting concept, but lost it's way. The hand of the author is obvious, so the story never really finds its own path. It just felt too forced and trying too hard to be philosophical. Tighter writing and focus may have helped - the characters didn't live, they were tools for another purpose.

[Eolann · Rating 3 out of 5]

Very interesting premise for a novel, to give full and considered attention to the inner life (in all senses) of an elderly French bulldog. I found the writing style to be a little rote, and overly similar to other somewhat experimental American authors like Lucy Ellmann and Joshua Ferris, but Day is able to maintain interest over the short length of the book.

[Valentina · Rating 5 out of 5]

This book changed how I see the world. It almost feels as though you get to walk inside death. You mourn people and beings that are still very much here. Also, now I lay in bed and wonder things like whether my cats can smell that I’m nauseous. Sobbed for a solid 1/4 of the book — a bajillion stars.

And we buck!
