Our Deadly Summer: 'Wistful, funny, sweet and just a small bit murder-y' Marian Keyes

Rate this book
'Tender, bittersweet and utterly hilarious. The final twist made me gasp' Daisy Buchanan

They said they'd never let a man get in the way of their friendship...


*

Laura and Dee haven't spoken since the day they buried a body together.

It was supposed to be the best summer of their lives. A break from university, from parents, from wasting their time on Irish boys with farmer's tans.

They'd imagined flirting with Ryan Phillippe on a New York rooftop. Instead, with summer jobs waitressing at a country club on Long Island, pickings are slim.

Mikey is a bully. Marco is off limits. Jose is angry. Mr Haight is a sleaze. Josh is too keen. And Other Josh… he's something else entirely.
It's a miracle only one of them ends up dead.

Dee is pretty sure she didn't mean to kill him. Laura, to her credit, never asked.

Not until she sends an email, out of the blue, more than twenty years later. It's finally time to mend the biggest heartbreak of that summer; Laura wants her best friend back.

A hilarious and heartfelt story about friendship, young women and bad men. Sarah Breen and Emer McLysaght bring their trademark Aisling humour in this completely new direction. Noughties nostalgia and a dead body, it's the novel you didn't know you needed.

345 pages, Kindle Edition

Emer, Sarah, my sisters in Christ WHO was drinking espresso martinis in 2001???

Look I'm a big Aisling fan. Love those books dearly, have returned to them more than once. They are all very real characters living in very real BGB as far as I'm concerned. So this just draws some probably unfair comparisons from me! But I didn't quite like this as much.

In the summer of 2001 Laura and Dee decide to go on a J1 to New York. Well, New York adjacent. They end up at a country club in the arse-end of Long Island. Despite that they have a great time. Sort of. It's up and down. It very much ends on a down with the two of them deciding what to do with a dead body on their last day.

I really enjoyed modern day Laura and Dee. They were so interesting to me! The reflections over that summer and their friendship versus who they are now was great. I think I just find people in their early 20s much less interesting to read about than older people so the fact that much of it was centred on their younger versions was unfortunate for me. I found the pacing a bit off too, it felt like a slog in the middle. Also if you cop the year it's set... well.

This is going to be such a hit this summer. And I will be glad to see it! Two authors that I will read everything from forever.

Laura and Dee haven’t spoken since the day they buried a body together in 2001. It was supposed to be the best summer of their lives. A break from university, from parents, from wasting their time on Irish boys with farmer’s tans. They’d imagined flirting with Ryan Phillippe on a New York rooftop but instead, with summer jobs waitressing at a country club on Long Island, pickings are slim. Mikey is a bully. Marco is off limits. Jose is angry. Mr Haight is a sleaze. Josh is too keen. And Other Josh… he’s something else entirely. It’s a miracle only one of them ends up dead.

This was such a fun read, packed full with nostalgia & humour, and I was engrossed from the beginning.

I loved how the story is perfectly intertwined, the present day merging with memories of the past, seamlessly flowing into one another, the reader being taken on this memory-provoking journey with Laura & Dee. There are laughs, there are tears, the friendship between these two best friends evident, despite everything that happens over their summer in 2001.

It gives a pure sense of reality throughout, the girls dreams of a perfect summer in New York not quite living up to expectations, balanced alongside the events that shape the future of the girls overall. I really liked the alternating character POV’s throughout, the two girls not quite having the same outlook of certain situations, giving the reader the feeling of embracing each moment with them. I would say this is definitely a book more about friendships than murder though!

I’m a big fan of Irish fiction writing and I am delighted to have discovered these two authors that I will definitely read more by. I have a feeling I will be having to check out the Aisling series written by these two authors, based on this I think it’s safe to say I will love! The perfect summer read, highly recommend!

Our Deadly Summer – Emer McLysaght & Sarah Breen
⭐️⭐️⭐️⭐️ / 5

Thank you to Rachel Quinn and Bloomsbury for my ARC copy.

This was such a fun, nostalgic, and darkly funny read. Our Deadly Summer perfectly captures that chaotic early-twenties energy - when friendships feel like the most important thing in the world and bad decisions somehow seem like good ideas at the time.

Laura and Dee’s story unfolds between the summer everything went wrong and the present day, and I loved slowly piecing together what actually happened. The premise alone is brilliant - two best friends who haven’t spoken in twenty years because they buried a body together - but the emotional core of the story is really about friendship, loyalty, and the complicated ways people grow apart.

Even though much of the story takes place in New York, it felt so wonderfully Irish. The humour, the voices, the observations about people - it all felt incredibly familiar in the best way. The cast of questionable men they encounter during that summer is both hilarious and infuriating, and the writing balances comedy with genuine heart.

And that final plot twist? My jaw was genuinely on the floor. I absolutely did not see it coming.

Sharp, nostalgic, and full of personality, this is a brilliant blend of friendship drama, dark humour, and noughties throwback vibes.

I thought this would be a fun book, “summer with a dead body and how to get rid of it vibes”, but so far what I’ve read is more about 20yo girls talking about hooking up with boys. and descriptions making me very uncomfortable. It might not be problematic for a lot more other people, reading is subjective after all, but this one isn’t for me.

Before writing this review, I wanted to check the premise of the book again because I felt like it promised me a book I didn’t get. Reading it again, I still feel a little like that but not as much as before. So it’s partly my fault too. But I have to say the title is pretty misleading as well.

When I saw this title, I expected this book to be more about the mystery. But after reading it, I find it fits more with general fiction than with mystery/thriller as a genre. There is a mystery, sure. But the book is about young women learning about the world they live in. It’s about nostalgia too which I’m not opposed to, I’m a millennial after all. However, the lack of emphasis on the mystery part, which was what caught my attention, impacted how I felt reading this book.
It started off well, to be fair. But the thing is that I expected it to be more about the present timeline and maybe the consequences of what had happened 20 years prior to this present time. And the book is mostly about the summer the girls spent in the US and everything they went through while they were there. So if that’s the book someone wants to read, this is a brilliant choice. I wanted a mystery and something a bit darker, maybe. I was looking forward to the Irish humour and their charm, which I did get. But sometimes it made me wish the book was more Irish, less the Irish girls are in the US and they’re fascinated by it. I’ve lived abroad so I get how it feels to do that but since it’s the US they went to, it felt less exciting for me personally.

The book is a lot about friendship but not just any friendship. The friendship of younger women, which is a genre on its own. I feel it was explored well here. Most of it felt very realistic and many of us can remember similar things we’ve been through at that time. The characters are a little bit older than I am but a lot of the pop culture stuff they mention is very familiar to me too, so that nostalgia factor was very well done as well.
At times, I felt it tries to make some commentary through the way the characters behaved in the past timelines but seen through who they are now. I can appreciate that but I felt it was a bit surface level. All the topics brought up felt a bit like that in a way. However, there was good commentary about all the girls and their different relationships with their parents and how that really affected how they behaved around other people. I did like that.

So when it comes to the mystery… it was very lackluster. I could guess what had happened pretty easily, even if there were some red herrings that were there to try and confuse the readers. I felt it was pretty obvious and I really feel that could have been expanded more in the present time when the characters talk about that person. There was just a comment and that was it. I don’t know, I felt I was constantly wanting more from the book but I never got it. And the ending was not satisfying at all.
Still, if what someone looks for in their next read is a book about that time period and about the complexities of female friendships, this is good for that. I wanted a mystery thriller so…we can share the blame for this one.

Thank you to Bloomsbury Publishing Plc and NetGalley for providing me with an early copy of this book in exchange for an honest review.

Pre-ordered this book last year so was I only delighted when Easons it shipped out this weekend just slightly ahead of its publication date.

In spite of it's grizzly premise, Our Deadly Summer is a witty and easy read that is filled with very early 2000s nostalgia (depending how much of a millenial you are, this could go either way) and a deep look at the complexity of young relationships - both romantic and platonic.

While the main plot of the book focuses on one terrible night in summer 2001 on a J1 and a dead body, perhaps the strongest themes in the pages are the ones the focus in on the the all-encompassing friendship that belongs to Dee and Laura in their early 20s. It is said that we never feel the same intensity in out later relationships than we did during out first love and the same goes for our early friendships. The characters of Dee and Laura gold up a mirror to young women and their first few years of earlt adulthood. They meet in college and instantly click, finally both happy to have a friend who understands them. They're besties and life out of each other's pockets during the time in college. This is a reality for most women at the same age when they have freedom from their families for the first time and their female friendships become the most important thing in the world.

But the authors are, as ever, true to reality, and don't shy away from the messy complexity that lives in the underbelly of many female friendships. Dee and Laura can be resentful, jealous and even downright cruel to each other throughout their summer in Long Island when one nabs herself a boyfriend and finds herself to distracted on what is meant to be 'the best summer of their lives'.

Woven in around this dynamic is the dead body at the first start of the page. This is a mystery with twists and turns that keeps you guessing until the very end.

More than anything, Our Deadly Summer is an ode to friendship, and the ones who would do anything for you. It is an ode to a time before your life changed and everything seemed so simple. It is an ode to a world we once knew that no longer exists.

Thanks to Netgalley and Bloomsbury for an early copy to review!

I’m only really giving four stars because this book was a little slow paced and I struggled to fully sink into it the way I usually do. But even so, I do think it was the right pace for the book and the story, even if it wasn’t quite for me.

TRIGGER WARNING: this book contains SA and violence, so if that’s not for you then feel free to avoid. It’s a big plot point so I’d avoid the whole book if this is a dealbreaker for you.

An odd thing seemed to happen while I was reading this book about two Irish girls and their summer abroad in the US as waitresses… I saw Irish women and things everywhere! Derry girls stars on tv quiz shows, Irish accents on drama shows I watch, just comments on Ireland coming up when i rarely hear much about it usually, very odd. It’s like the universe went on a theme matching mission for the week I was reading this.

So I felt a little closer to Dee and Laura this week. And they’re already lovely, flawed characters so this was quite nice actually.

Dee is a girl who is close to her family and worried about a lot of things; whether her family is proud of her, if she’s managing to save enough money, if she’s doing okay as a waitress, and how much she actually likes boys. Very easy to identify with, as someone who was a young woman who didn’t know she was gay and was a ball of anxiety.

Laura is less like me, but the insecurities of girls in their early twenties are universally identifiable. She’s the girl I thought I should be when I was younger, and I probably would have ended up just as unhappy as her if I’d been better at it.

Seeing them young and then how they ended up twenty-four years later was very sweet and emotional. Even ignoring the major event they go through together, it brought up feelings of inadequacy and worry about having made the right choices in life, a little tough but this book was just so REAL.

It’s an intense book, but in a good way. Give it a shot if that sounds like something you’d enjoy.

Our Deadly Summer is an incredible blend of dark comedy, nostalgia, suspense and heartbreak and the kind of novel that hooks you immediately. The authors have created a story that feels entertaining on the surface while quietly delivering something much deeper underneath.

Set between a chaotic summer in New York in 2001 and the present day, the novel follows former best friends Laura and Dee, whose lives were permanently altered by one terrible secret. The pacing is super: every chapter peels back another layer of what happened that summer, balancing genuine tension with razor-sharp humour and painfully accurate observations about friendship, ambition and growing older.
The friendship between Laura and Dee captures the intensity of youthful female friendships perfectly: the kind that can feel all-consuming, transformative and, occasionally even destructive.

McLysaght and Breen also evoke early-2000s nostalgia absolutely brilliantly. The New York sections are vivid and electric, full of freedom, recklessness and the illusion of invincibility that defines your early twenties. Yet beneath the glamour and humour is a constant undercurrent of dread that builds masterfully toward the final revelations. (My eyes were 👀👀 for THAT bit!)

The dialogue sparkles throughout, delivering laugh-out-loud moments without ever undermining the emotional weight of the story. I personally think that balance of funny and dark, warm and unsettling, is incredibly difficult to achieve, but this novel pulls it off effortlessly.

By the end, Our Deadly Summer becomes much more than a thriller. It’s a story about guilt, memory, reinvention, and the people who shape us long after we’ve tried to leave the past behind.
Sharp, addictive and surprisingly emotional, this is one of the most enjoyable contemporary Irish novels I’ve read in a long time. Perfect for fans of character-driven thrillers with wit, heart and a killer sense of atmosphere.

This was my first visit to the world of these authors and I read it in less than 24 hours - I just couldn't put it down.

Irish best friends Laura and Dee haven't spoken since an ill-fated summer working abroad during a college holiday, which ended with a dead body in their cabin. 25 years later and now in their mid forties, the death of their mentor for that summer gets them talking again and remembering their time waitressing at a country club in Long Island. The girls were best friends having bonded over the fact that neither fit in at such a posh university, and they were determined to have an amazing summer making money, meeting boys and generally having a deadly (great) time. But a country club before the Me Too movement was full of bad men with few morals and very little penalty for their actions. One of them was bound to wind up dead eventually. Dee didn't mean to kill him, but Laura will help her clear up the mess as that's what best friends do.

I started this book expecting a murder mystery but quite quickly realised it's far more of a coming-of-age story which happens to feature a covered-up death. We relive the summer of 2001 through Laura and Dee's eyes, with all the ups and downs that 20 year olds go through from falling out over boyfriends to boozy nights out and the perils of sharing a house with strangers. There were so many men in this story who were potentially going to end up dead because of their behaviour, and yet none of them felt like people I hadn't encountered at that age and around that era. Laura and Dee are a modern Thelma and Louise, even referencing it themselves at one point. When we move back to them reuniting in the present, it's lovely to see that they still haven't drifted apart emotionally despite years of radio silence. It's a realistic friendship and the whole story is so reminiscent of what early noughties life was like too. Oh and there's also a bad man who definitely deserved to be punished.

Like so many readers across Ireland, I completely fell in love with the Aisling series. Naturally, when I saw that Emer McLysaght and Sarah Breen were branching out into a brand new standalone novel, it automatically became a highly anticipated read for me. Unfortunately, while it was an interesting shift in tone, it didn't quite live up to the high standards set by their previous work.

In my view, a thriller or mystery that opens with a dead body is always off to an excellent start. The premise, centered around a chaotic noughties Long Island J1 summer and a long hidden secret, instantly hooked me. However, after that sharp opening, the plot really started to drag. We don't find out the true identity of the victim until very late in the novel, and while the authors dangle a few different possibilities throughout the pages, the middle section simply felt much longer than it needed to be.

Because the narrative felt like it was treading water, it was hard to maintain attention throughout. Don’t get me wrong, there are definitely a few witty lines scattered throughout that showcase the authors' trademark humor, and it isn't a bad book by any stretch of the imagination. It just failed to capture my heart or my suspense radar the way I hoped it would. The real momentum didn't kick back in until about the 85% mark, which made the final payoff feel a bit too distant.

If you are looking for a nostalgic, bittersweet look at female friendship with a side of mystery, this might hit the mark for you. But for readers expecting the relentless tension of a standard crime novel or the sheer, undeniable charm of Aisling, this one sits at a solid 3 stars. I was simply expecting a bit more given their incredible track record.

My thanks to NetGalley and the publisher for providing me with an ARC of this book.

Our Deadly Summer* by Sarah Breen and Emer McLysaght is the long awaited, much anticipated, new novel from the duo that brought us the beloved OMGWACA series. Story-wise, this is a complete departure from the ‘Aisling’ universe but there are a lot of similarities in humour, tone and style that many readers will enjoy.

Deirdre is from a small town, raised by loving yet overbearing parents, and has a healthy respect for money. Laura is a wealthy petrol station heiress, largely invisible to her family, but an apartment on Townsend Street and an unlimited allowance help soften the blow. Despite their differences, the girls are joined at the hip and off they pop in summer 2001 to New York City on a J1, determined to make loads of money (Deirdre) and shag loads of boys (Laura).

Working at a country club for the season, the girls spend their days serving high society and their nights drinking at the local dive bar. A series of men punctuate their summer, from grumpy groundskeeper José and abhorrent club member Mr Haight, to sexy Josh and his handsy pal Other Josh. But one run in with one particularly bad man sees the girls burying a dead body and never speaking to each other again. Now, 24 years later, they reconnect and are forced to confront some long buried secrets.

I can't say that I felt the same sort of magic from the J1 girls as I did with the ‘Aisling’ cast of characters. While I am conscious that the books are absolutely separate entities, I found it hard not to draw comparisons because Our Deadly Summer’s voice felt so very Aisling at times. With a May release, this book is going to do numbers as a summertime read and I anticipate it sitting top of the charts for many weeks. Out 21/5/26

This will 100% be the book of the summer.

Our Deadly Summer by Emer McLysaght and Sarah Breen isn't what I expected. I knew the premise; friends find themselves in a harrowing situation where they have to bury a body, an inconvenience on their J1 to long island. I knew it would be funny, but I expected more grit and misery, considering the subject matter. What I got instead was a strangely warm and beautifully nostalgic tale of soul friendship, centred around a seemingly accidental death. And I loved it!

Less of a whodunnit and more of who-carked-it, the book opens with Laura and Dee figuring out how to deal with the body lying on the floor of their country club cottage. As the story unfolds, it's quickly transparent that this isn't necessarily a book about what happened that night. It's a book about what it is like to be in the body and mind of a woman in her early 20s. It's about how our young adulthood years can form so much of who we become, for better or worse. It's about the ways in which we learn to protect ourselves, especially as women. Mostly though, it's a book about friendship, and McLysaght and Breen write the friendship between Laura and Dee so beautifully. They do such a brilliant job of showing that, although we might think we know everything about those closest to us, we all have our insecurities and our secrets.

I was so immersed in the peaks and troughs of their bond, and was rooting for them so deeply that figuring out who it was lying on the cottage floor was secondary to how their friendship would end up.

I couldn't put this book down. The last few chapters are so compelling and at times pretty hilarious. This will be clutched in the hands of every pool side lounger this summer, I can tell.

Thanks to @bloomsburypublishing for approving me to read an ARC on Netgalley. I so enjoyed it.

@emerthescreamer and @sarahjaybee make such a great team. But sure we knew that already!

‘You’ve always told me you’d help me bury a body, no questions asked, and …’ ‘I always said I’d be your alibi,’Dee finished.She was so relieved she managed a weak smile.‘I just never thought it would be the other way around.’

Dee and Laura haven’t spoken in almost 24 years, not since that fateful last day of summer. Once inseparable best friends, they’ve been no contact since they buried a body together. That is until an out of the blue email from Laura gives them a chance at reconciliation. What really happened that summer and can they be friends again?

Our Deadly Summer follows multiple timelines - following their summer in the states when they were 20, the last day of summer and the present day 24 years later. We see the highs of their summer and the lows. From nights out with their housemates, to finding love and falling out. Their summer is messy - but they were 20 and in a different country, so it’s obviously going to be. There’s going to be young love, drunken nights out and plenty of shenanigans.

I enjoyed how the book slowly pieced together the timeline of that last day of summer. I thought I knew where it was going but it took a turn I didn’t expect.

“It’s almost painful, the longing to go back and change things. The regrets. She finds herself sometimes drowning in memories of the time before, chasing the nostalgia like an addict. Imagining how things might have turned out.”

Despite the murder, this book was so funny and had a nostalgic vibe. Especially with the comparisons of modern day to them in their 20s. And I really enjoyed it! At its core it’s about female friendship, and I loved Dee and Lauras. This is a book I’d recommend.

Our Deadly Summer is a sharply funny, bittersweet, and wonderfully chaotic dive into the intensity of female friendship, the perils of bad men, and the kind of summer you spend the rest of your life trying to forget. Sarah Breen and Emer McLysaght take their trademark humour in a darker, twistier direction, and it works beautifully.

Laura and Dee’s story unfolds with the irresistible pull of nostalgia — sunburnt days, questionable choices, and the kind of friendship that feels like a lifeline. Their Long Island summer job is meant to be a glamorous escape, but instead they find themselves surrounded by a cast of men who are variously sleazy, cruel, off‑limits, or simply disappointing. The authors capture that early‑twenties mix of bravado and vulnerability with pitch‑perfect clarity.

The novel’s opening line — that the two haven’t spoken since they buried a body — sets the tone for a story that balances humour with genuine emotional weight. The mystery of what really happened that summer is threaded through with tenderness and sharp observation, and the final twist lands with a gasp. But the heart of the book lies in the complicated, fiercely loyal bond between Laura and Dee, and the ache of a friendship that once felt unbreakable.

Breen and McLysaght deliver a story that’s riotously funny, unexpectedly moving, and steeped in noughties nostalgia. It’s a clever, heartfelt look at the women we were, the women we became, and the friendships that shape us long after the summer ends.

Thank you to Bloomsbury Publishing Plc (UK & ANZ) and NetGalley for this ARC.

As a big fan of the Aisling series, I think it’s important to say straight away: this is not another happy-go-lucky Aisling-style read. And honestly, I think that may be why some readers are struggling with it.

I went into this one without expecting it to be the same kind of book, and I’m glad I did, because Our Deadly Summer is actually a really interesting read.

The story follows two young Irish women who head to the US for the summer after finishing secondary school. They are waiting for their Leaving Cert results, hoping to earn some money, and working in a hotel in New York. They are young, a bit naive, and very much at that in-between stage of life where you think you’re grown up… but life is about to prove otherwise. Rude, honestly.

When one of them kills a man in self-defence, the summer turns into something much darker, and they are forced to deal with the aftermath of one terrifying moment.

What I appreciated most was the way the book explored female friendship, growing up, relationships, loyalty, fear, and the complicated choices young women are sometimes forced to make. It has a much heavier tone than I expected, but I actually liked seeing the authors explore something different.

So, if you’re looking for another Aisling-type book, this is probably not it. But if you go in knowing this is a darker, more coming-of-age story with serious themes, I think there’s a lot to appreciate here.

A thought-provoking and engaging read.

I love Sarah and Emer, and enjoyed the Aisling series, but I'm going to be brutally honest (I'm sorry) and say that Our Deadly Summer just didn't do it for me. Plot, pacing, execution - all fell flat.

I'm the right age for this book, having grown up in the 90s in Ireland and having done several summers abroad (and all the madness that brings) in the late 90s and turn of the century during my university days, but I found the plotline here about Laura and Dee on a J1 US working holiday visa in the summer of 2001 very drawn out. Two characters named Josh and the ins and outs of restaurant service and rostering were a no-no for me.

The book opens with Laura and Dee confronted with having to hide a dead body. We know it's a man but we don't know who it is until the very end, so the reader is hooked to an extent.

I felt the story was somewhat redeemed by the last section set in the present day when the girls meet again. I saw a reviewer on Goodreads say that older Laura and Dee were so much more interesting, and I can only concur with that. I'd have enjoyed the story much more had more of it been set in the present. It felt more authentic, less reliant on Irishisms and drunken tropes than the 2001 storyline. I really hoped I'd love this but it wasn't to be.

Many thanks to Bloomsbury Publishing and to the authors for the advance copy via Netgalley. Our Deadly Summer is published this month (May 2026).

If there was ever a book whose ending came out of left field - so much so that if I was reading a paper copy I would have thrown it across the room - it's this book.
Oh dear... and it started off so well...
We start with two best friends taking the summer before Uni to go work in New York to get some life experience and money. They are going to work in a country club in a remote town. I say remote, it kinda is but there's still plenty of nightlife for their drinking and debauchery.
We also know from the get-go that there's a dead body that they need to deal with. And for the majority of the book the deceased is unknown.
We also know that since that night, after they left, they haven't seen or spoken to each other... but they start to reconnect via email...
Sounds a good book - well... it could have been. It's a great premise, after all. But, after reading through so much of the aforementioned debauchery to get to the "what happened that night" and then finding out who was dead... well... that just descended into farce and incredulity for me.
Oh and I am also not sure where the humour was... obviously not to my taste. I guess it's probably a me thing, I just didn't click with the authors' style...
I did have the Aisling books on my periphery but I think maybe I'll give them a miss after my experience herein. I actually wish that I'd DNFd this one...
My thanks go to the Publisher and Netgalley for the chance to read this book.

Our Deadly Summer by Emer McLysaght and Sarah Breen immediately snagged me with the synopsis - "Noughties nostalgia and a dead body, the novel you didn't know you needed" - and as a GenXr, I immediately got on board to relive those days, well, maybe not the dead body part, but I couln't wait to read the story of two intrepid friends of the era, even if they unalived someone right? Oho, I was not disappointed, what a spanker of a novel!

Laura and Dee were all ramped up for a glorious Summer. The besties were raring to go, but one man after another kept stomping on the good vibes and making life complicated, ultra complicated when one of the men appears to be rather expired

By now you will know I lovbe me a dual POV and throw in a dual timeline and I am hooked! The characters are easily defined and the character development is beautiful 2026 is the year of discovery imo and I am gratified to have discovered Emer McLysaght and Sarah Breen through this absolute belter of a novel. Yes please, more please!

Thank you to Netgalley, Bloomsbury Publishing Plc (UK & ANZ) and the incredible authors Emer McLysaght and Sarah Breen foir this awesome ARC. My review is left voluntarily and all opinions are my own

Thank you to NetGalley for the chance to read Our Deadly Summer.

Our Deadly Summer sees Emer McLysaght and Sarah Breen have written a book that’s both very funny and quietly reflective.

The novel centres on the characters of Laura and Dee, Trinity College friends who headed to New York in the early 2000s expecting sun, freedom and core memories. Instead, working at an exclusive country club on Long Island brings them face to face with entitled employers, awkward romances and mounting tensions. Then events spiral dramatically and a dead body changes everything. What begins as a coming of age holiday shifts into something darker, setting in motion consequences that echo for decades.

The story unfolds across timelines, with a later reconnection between the women forcing them to confront what really happened that summer and why their friendship fractured. It’s this emotional strand that gives the book its depth. The authors balance irreverent wit with genuine warmth. The 90's setting is well observed, full of nostalgia and cultural detail, and the dialogue has a natural, easy rhythm.

Entertaining, bittersweet and very readable, Our Deadly Summer blends humour with heart and was a pleasure to read.

Our Deadly Summer has a really intriguing premise and a strong focus on friendship that kept me interested throughout. The story follows Laura and Dee, two former best friends who share a dark secret from a summer decades earlier, and I enjoyed seeing how their complicated relationship unfolded over time.

One of the highlights of the book is the mix of humour and nostalgia. The writing captures the messy, chaotic feeling of being young and making questionable choices, and there are moments that are genuinely funny despite the darker subject matter. The authors clearly have a knack for writing relatable female friendships.

However, the pacing felt uneven at times. Parts of the middle dragged a little for me, and I found myself wishing the plot would move forward more quickly. I also struggled to fully connect with some of the characters, which made it harder to feel invested in the mystery behind the events of that summer.

Overall, this was an enjoyable read with an interesting concept and some strong moments, but it didn’t quite live up to the potential of its premise for me. If you enjoy character-driven stories about complicated friendships with a dark twist, this one may still be worth picking up.

I loved OMGWACA from the Irish writer duo Emer McLysaght and Sarah Breen so I was delighted to receive an advance copy of their new novel 'Our Deadly Summer' from NetGalley and Bloomsbury Publishing.
Dee and Laura are two college friends who are spending the summer of 2001 waitressing in an exclusive club on Long Island on a J1 visa. During that time they are faced with a challenge that at the end of the summer makes them lose touch. After 20-odd years they reconnect and reflect on their stay in America.
The story is told from the perspectives of Laura and Dee interspersed with flashbacks of what happened on the last day of summer.
I enjoyed reading about their adventures abroad and the feeling of being young, intrepid and away from home as we probably all have experienced at some time. However at times the story dragged a little for me. The last chapter which is set in the present I really enjoyed though. It also brought the story together. Laura and Dee are two very different but likeable characters and the novel focuses heavily on their friendship. The title is brilliant as 'deadly' here has two meanings, the literal one and in Irish slang for brilliant or great.
With it's summer setting and at times funny writing no doubt this will be popular for holiday reading.

I have mixed feelings about this book.

From the beginning you know the premise that there is a dead body, however it is not until the very end of the book that it is revealed who has been murdered. Naturally, I had thoughts about who it would be (I won't spoil it here) but the reveal of the person just did not make sense with the rest of the book. It wasn't a twist, it was completely jarring. There had been no indication throughout the novel that the person was potentially abusive and their sudden 'felon backstory' that no one knew about was really incongruous.

That being said, other parts of the book were really enjoyable. Five women in their early twenties working for the summer and sharing a house. We all know the carnage that can ensue and this is where I think the book gets it right. Set in the early noughties the fashion and pop culture references made total sense. The girls were portrayed as women you knew (or were) in your twenties.

I found that the pacing of the book to be a little slow. Not a lot happened in many parts of the book, which could be heavily edited to make it a shorter story and still have the same effect.

A nice read but not great.

Thoughts:
This is such a complex and interesting book. At its heart it’s all about women, femininity and female friendships but the mystery element of what happened on The Last Day of Summer added a building tension throughout. The quick chapters and changing timelines helped build unease very quickly, especially at the beginning. I liked the Dual POV and the way it let us see how the summer unfolded from both sides of the friendship. I found the victim from summer quite illusive with me at one point considering 6 people I thought it could be and I was still wrong. The girls in Deuce were all well thought out characters and it was interesting to see how they interacted coming from such different backgrounds, especially the rich English girl being thrown in with 4 Irish girls. I also liked some of the lesser mentioned characters, Dolly specifically because she was such a caring character when she was brought in and the barman was quite entertaining too.

Favourite Quote:
“You can tell a lot about a man by how he treats servers and I'd never once heard him say please or thank you. Manners cost nothing.”

I read the Ashling series of books that the authors released previously and really enjoyed them. So when I heard about Our Deadly Summer I was looking forward to reading it. The story revolves around Dee and Laura, two best friends in college looking for fun who decide to go on their J1 for the summer to New York. Sun, hunky guys and working at a country club, how much more “deadly” will their summer be?!

I enjoyed reading about the friendship between Laura and Dee during their summer with the girls in the US and how they felt now over twenty years later reflecting on that summer. I would have liked a little more focus on the mystery aspect of the story. I didn’t see the twists and turns coming throughout the book, which was a great surprise.

The ending really summed up the book well and I loved the focus on female friendships throughout the book. For any fans of the Ashling books, this will be a must read. Definitely recommend Our Deadly Summer as a summer read that will keep you gripped from start to finish. Thank you to Bloomsbury publishing and NetGalley for this arc in exchange for an honest review.

Have you ever said you’d help your best friend bury a body? Yeah, me too. But what happens afterwards.

Our Deadly Summer is a love letter to friendship and sisterhood wrapped in a layered tale of secrets and dead boys. It spans two decades, straddling the summer Josh died and twenty-four years later when our best friends collide again after so long apart. We see that fateful night before walking down memory lane into Dee and Laura’s history, and I could almost feel the sepia-filter, sunny nostalgia in my bones.

For me though, it felt very start-stop, and by the time we’d reached the present again I almost forgot what book I was reading. Even though the writing style might not have worked for me personally, the characters were absolutely the stars of the show. They were so real, so funny, so beautifully flawed — from their hot mess twenties to their adult lives acting like they know what they’re doing.

It’s less of a murder mystery with secrets and intrigue and more of a coming of age story about friendship with an unfortunate chapter.

I would like to thank Netgalley and Bloomsbury publishing Plc for this advance copy of Our Deadly Summer by Emer McLysaght and Sarah Breen. I would have read all previous novels (the OMGWACA series) and really enjoyed them, so i was eager to read this stand alone novel. We meet Dee and Laura, who become instant best friends in college, and then go to america on a J1. There isnt too many similarities to the Aisling books, and I thought this was refreshing. The book cycles between their college years in the early noughties, to present day. I absolutely adored this book. For the simple reason, I went traveling with my best friend in the early noughties, and this book brought back so many memories, and it recreated a lot of the feelings, good and bad of "being away".  But that aside, i think many people will relate to this story as the girls friendship is really brought to life, and is utterly heartwarming.... other than the ever so slightly serious subject matter of the book. If I could give this book 6 stars, I would. Or a lest 5 stars,  and a heart ❤️

combined, friendship, nostalgia, and a little bit if murder!

Our Deadly Summer follows the story of college besties, Laura and Dee, and a summer that changed their lives and their friendship forever.

The dual timeline and spilt POV worked really well with this story. It's very clear from the opening chapters that the two no longer speak, and there was instant intruige for me to find out what happened to fracture their friendship so deeply.

I found the "then" chapters that explore the summer, such easy reading, and the "noughties" nostalgia added a little extra for me, and whilst the middle of the book is a little slowburn, it cleverly explores potential victims and motive.

One slight critism for me would be that there's quite a lot of characters. It does work well to add mystery as to who the unidentified corpse could be, (there's a few s@%tty males in here), but I did get a little confused at times.

Other than that little niggle I found it a good read with likeable characters, some moments of humour and a book that brings the suspense.
