The October Arrangement: A Fall Forced Proximity Billionaire Romance

Rate this book
One penthouse. One month. Ten rules. What could possibly go wrong?

Bella

After the company I worked for closed, I was offered a temporary job in New York.

A change of scenery. A chance to get my life back on track.

Thanks to my college friend Daisy, I even had a beautiful Manhattan penthouse to stay in while her cousin was away on business.

Except he came home two months early.

Simon Montclair is gorgeous, infuriating, and very unhappy to find me living in his home.

He wants me gone, but I have nowhere else to go. So, we make an arrangement.

I can stay until the end of October as long as I follow his list of rules.

Living with Simon should have been unbearable.

Instead, somewhere between our arguments, late-night conversations, and the undeniable attraction neither of us expected, I started wishing October didn’t have an expiration date.

Simon

I like my life exactly the way it is.

Controlled, uncomplicated, and relationship-free.

Then I came home and found Bella Castle in my penthouse.

She wasn’t supposed to be there, and I sure wasn’t supposed to let her stay.

But Bella has a way of getting under my skin and making herself at home in places she doesn’t belong.

First, my penthouse.

Then my thoughts.

And eventually, the one place I swore I’d never let a woman anywhere near.

My heart.

Our arrangement ends October 31st.

The problem is I’m not sure I want it to anymore.

Fall in New York gets complicated in this steamy billionaire romance featuring forced proximity, unexpected roommates, witty banter, undeniable chemistry, and an October arrangement that changes everything.

Really loved this book. Loved Simon’s character growth over the book and the banter was off the charts. This was a great read! I also really loved Simon’s relationship with his dad. Would have liked to see Bella’s relationship with her mom, but she was barely mentioned. Highly recommend this one!!

🍁The October Arrangement, Sandi Lynn
286 pagini

🍁Posibile spoilere!
🍁Bella Castle este nevoită, după ce rămâne fără slujbă, să accepte o ofertă temporară pentru o lună la New York, numai aceasta nu vine la pachet și cu o locuință și astfel apelează la prietena sa, Daisy pentru a o ajuta. Și cum Daisy are un var care este plecat pentru trei luni, o instalează pe Bella în apartamentul acestuia.
🍁Simon Montclaire este un bărbat care muncește pe rupte, care nu are relații și preferă liniștea și disciplina casei sale. Totul se schimbă când, întorcându-se mai devreme cu două luni de la Los Angels, găsește în locuința sa un intrus, asta dacă nu punem la socoteală și invazia de dovleci din apartament. Acest intrus este nimeni alta decât Bella, care se vede nevoită să dea explicații cu privire la motivul pentru care se află acolo și mai ales trebuie să îl convingă pe intransigentul și seriosul Simon să accepte prezența ei până la sfârșitul lunii octombrie, când contactul ei se termină.
🍁Bella mișcă ceva în inimă împietrită a lui Simon, iar acesta îi permite să rămână numai și numai dacă va respecta cele zece reguli impuse de el, reguli care sunt puțin cam absurde, dacă mă întrebați pe mine. Astfel cei doi ajung să petreacă timp împreuna, și cumva totul se schimbă deoarece cu cat se cunosc mai bine, cu atât scot la iveală tot ce au mai bun, și cumva primul care încalcă regulile nu este Bella, ci Simon. De ce le încalcă și cum se va sfârși povestea celor doi rămâne să descoperiți voi.
🍁Este prima mea întâlnire cu autoarea și cu siguranță nu va fi nici ultima deoarece mi-a plăcut mult povestea veselei Bella și a morocănosului Simon. Mi-a plăcut cum Bella dărâmă zidurile din jurul inimii acestuia, mi-a plăcut cum reușește să-l sculata din rutina zilnică și să îi arate ca viața înseamnă mult mai mult decât munca și planuri bine stabilite, mi-a plăcut să văd cum nesiguranțele Bellei sunt îndepărtate de Simon, cum acesta crede în ea și în munca ei, dar cel mai mult mi-a plăcut starea de bine pe care mi-a dat-o cartea și marele zâmbet cu care am încheiat lectura. Așa ca dacă vreți să citiți un roman cu aroma de toamnă, acesta este alegerea perfectă.

In theory I should freaking love this book, it got all the right ingredients:
Safe - no OWD or OMD
No third act break up
Cute MMC’s Dad
Richy rich MMC
Meet cute

BUT I just couldn’t put my fingers on why this didn’t shoot up in my favourite list. I’m not even sure what to rate this book. It’s just kind of fell flat for me with the first sex scene and it remained flat-ish, and the last few chapters is just a long epilogue but because I’m me I was expecting something to happen.
It’s also mentioned he pretty much only does ONS at least nothing more than a week, so at times it felt like the FMC was convenient.

The October Arrangement

This story was such a fun read. Two people who were so opposite, he was obsessed with everything being a certain way, and Bella just the opposite of it with his ways. Soon their back and forth banter is what made them both happy to be together, and drawn to each other. This story is so much better with them both, fun, flirty, his bossiness, her not having any of it. Her skill with her talent/skill in her job brought them even closer. Absolutely loved this story, great read.

Sorry but this is just not a good book. No plot, no conflict, no chemistry or tension, amateurish writing, cringey dialogue, and more than a quarter of the book is essentially an extended epilogue.

Funny. Lots of banter. Not love at first sight, but he falls hard.
No big drama. No OW, OM.
Simon has an adorable father.
Harold the pumpkin was a stand up guy.

I always have two emotions whenever a new Sandi book comes out. It’s the feeling of excitement but also hesitancy with it. The past standalones I’ve read by her have been questionable but good choices. For this one, I liked the direction it was heading in the beginning but then it kind of bypassed moments in time and skipped some key sex and intimacy scenes. I also felt like it did a sudden change in Simon that just happened and didn’t really build up the attraction he felt towards Bella. It didn’t do it for her either with him. He kind of just woke up one day and decided he didn’t want to stay away from her anymore. There wasn’t any longing I felt with him or Bella towards each other. There was an interest, but no carnal or passionate thoughts they felt with each other. It was more like, oh, she’s beautiful but I don’t feel like sleeping with her. I got a little bit more of that with Bella towards Simon but nothing that screamed she wanted to rip his clothes off and go at it with him. I didn’t get that vibe from him about her either. I would have liked more of those thoughts and feelings between the two of them. It would have set a different vibe for the story but I think the book could have benefited from that. It would have at least got me to give it a 5 if those feelings and actions played a more present role. If you take that away, the general plot of Bella going into Simon’s world and him adjusting to her chaos was great. I love a story about a woman who upends the man’s life and gets him to question everything he was doing before. This ends up resulting with the man basically being forced to change because he cares about the woman making the changes. He wants to see her happy even though he will moan and groan about it and deny it for years to come. Of course Sandi can’t finish the book with a proposal. She ends up having to do her signature adding of extra chapters that go into the future from 6 months later up to 13 years later which are always not necessary. When you combine that with the lack of passion or need of wanting a person so badly you can’t wait and will have them immediately then it loses some intensity and interest for me. In the end you wind up giving a 4 rating because of this missing element and the continuation of the story when it isn’t necessary.

I swear to god, I have no idea how some books get such ratings. I tried to power through this one but I just couldn’t. If someone I trusted let a total stranger LIVE IN MY APARTMENT while I was away, I would literally call the police on both of them. Your home is SACRED. What’s-her-face, the FMC, is incredibly immature and childish. Simon was a stereotype. I did like the dad trying to match make but that didn’t make up for the rest of it. If I read ONE MORE line like “‘blah blah blah whatever dialogue,’ I smiled”; or “‘blah blah blah whatever dialogue,’ he smiled,” I was going to LOSE MY MIND. There was also a lot of smirking through lines. Oh, and if the FMC said, “I’m from Massachusetts” ONE MORE TIME… 🤦🏻‍♀️💀 The was it was stated was always in this weird way as though Massachusetts was some tiny town, or at least that it doesn’t have large cities and culture and ummmm… FALL?! I can GUARANTEE you that fall anywhere in Mass is a far cry better than fall in freaking MANHATTAN. Here’s a hint: it’s like Central Park but it’s the WHOLE STATE that’s covered in colorful trees. There is also no mention of where in Mass she’s from. Boston? The Cape? The North Shore? The Berkshire half? The middle? Small town? City? The name of her former company might suggest coastal but who is happy to leave coastal New England for NYC?!?! Maybe some people, but not this New England girl. Oh and then she uses all this fake fall decor for her shots?! I don’t know what this company was selling but I wouldn’t buy anything that was advertised with a fake BLUE pumpkin with a bow tie 🙄 I also wouldn’t pay anyone for doing that work either. And was she just wandering New York with no parameters on what she was doing? I got to him asking her on a date-not-date with next to zero buildup or chemistry and finally quit.

Underdeveloped potential

Weirdly, this book was underdeveloped in the connection between Simon and Bella even with the device of using two point of views. The chemistry was simply stated rather than revealed through descriptions of their thoughts and physical reactions. The plot felt very rushed for them to have no time to learn about each other and fall in love in two weeks. The sex was rushed, skimmed, and unrealistic. I wonder if the author is scared to write a decent sex scene. Simon surrendered way too easily and I have no idea why he was so flatly portrayed in such a 2D way. It was hardly believable.
Way too much time spent on the after falling in love part. Scene transitions are weak and not consistently delineated. My advice to the author is to get a good editor to push you into elevating your craft. The dialogue is good, you have talent there. You can outline and craft a story, but the characters lack depth, flaws, motivations, and believable character development for how short the story actually is. The story telling reads as amateurish when compared to a master storyteller like Rebecca Yarros. It needed more plot devoted to falling in love and one short epilogue to balance it better. This could have been much better written.

A twist from the usual

I loved this story. Finally a man who knew what he wanted and goes after it. Simon, sturdy, always planning, had his rules for everything, and a quiet place to land, his penthouse, where nothing was ever out of place. Bella, A sassy, straight talking gal, with no holds barred. Bella comes to NY needing a place to stay and ends up in a penthouse without the owner's knowledge. Enter Simon, owner, and not happy to find a strange woman wrapped in a towel standing in his home, A pumpkin layout on his fireplace, and of course blue Harold in a bow tie on the coffee table. Who wouldn't throw a fit? A fit of laughter anyway. Anyway Simon lets Bella stay after she signs his 10 rules. William, Simon's dad, you gotta love him, Christian too. Both hilarious. The rest you have to read. It's a good story. Not the usual grumpy billionaire meets lady who sets his world on edge but he has to lose her before he can admit he loves her....so glad that wasn't this story, enjoy!

Five Stars for Bella and This Addictive Story! ⭐️

Omg!!! This book was SO good! 😍📚 October Arraignment by Sandi Lynn completely pulled me in!

I absolutely loved Bella! She is strong, talented, confident, and knows exactly how to handle Simon. And let me just say… Simon had NO idea what was in store for him when he came home to Bella! 😂🔥

I loved watching their story unfold. The chemistry, tension, emotions, and unexpected moments kept me turning the pages because I just had to know what was going to happen next. Bella is such a memorable character, and I loved her strength and the way she stood her ground.

Sandi Lynn definitely knows how to create characters that grab your attention and a story that keeps you invested. This was such an entertaining and addictive read!

If you love romance with strong characters, undeniable chemistry, and plenty of twists and emotions, definitely add October Arraignment to your TBR!

⭐️⭐️⭐️⭐️⭐️

Ten rules

What a totally delightful book. Full of humour and experiences of life that we can all encounter especially at the ends of the story. Bella is a down to earth character that finds herself out of a job and moving to New York, pulling in favours she arrives at an empty penthouse flat for 3 months rent free, but in charge of a cat called Raine. Bliss for her as her friend from college believes tge grumpy owner is in LA, for three momths!!! Not so on his return , Simon the owner of said flat is horrified to find a from mate!! The story really unfolds from this point and what follows is/ beautiful love story and a great HEA. The characters are well described and of endearing characters, and a lovely example of growing relationships emerge. A great storyline that is both interesting, absorbing and a delight to experience, and thoroughly recommended.

This was a really cute, simple read. If you’re looking for a short, sweet romance that comes in a pretty bow. This is for you.

Bella lost her job and moves to NYC for a new opportunity. Problem is, she has no place to live. A friend offers her a place to stay at her cousin, Simon’s penthouse while he is away on business for 3 months. Simon returns early and finds Bella in his penthouse much to his surprise. Simon is a little bit of the grumpy billionaire but eventually agrees to let Bella stay with him for 30 days. Over time the two become closer and eventually fall for one another.

This story moves at a face pace and there really isn’t a “problem”. The two are really cute together with no drama thrown in. It was sweet and simple. A perfect book between reads.

Another Great Happy Read!

I loved this cute story like slightly different from all the other books and I’ve read every single book Sandi Lynn and written! Been a fan since day one! I will say tho characters need new names just feels weird reading the same name from all the other books. But that’s all I love how her books are all feel good reads at least for myself personally. Big fan of Sandi Lynn!

Wonderful read

I rated The October Arrangement 5 stars because it is a well written romance with some of the best conversations and snappy repartee that I have read in a long time. The author makes it flow effortlessly, adding charm, wit, flirting and more. The story is entertaining with some interesting twists, making it an all around great story for contemporary romance lovers.
Loved it!

Perfect!!

I enjoyed Simon and Bella a lot. Simon met Bella when he came home early from a business trip to find her standing in his kitchen. His cousin let her stay there and he didn't know and didn't like it at all. He agreed to let her stay for a month if she followed ten rules which she ended up breaking them all. He didn't plan on falling in love with her. She definitely wasn't in his planned out life.

Just not very good… very basic, boring, sadly. I thought for sure this was a debut novel for a novice writer so imagine my surprise at how many books this author has published! I’m not even sure what to say because that makes it even worse. The writing & punctuation just seemed almost juvenile. To be fair, this is the only book I’ve (attempted) read by this author, so maybe the others are better? But this one was not for me.

Above and beyond

Well done Sandi, you got past the proposal, the Ring, the wedding and wrote a lovely story about what happens afterwards right until their twins come back from a visit from Harvard! Such a good story. Being there done that. The story started off slow with the usual tropes and I nearly gave up. I’m glad I didn’t. I think it was one of the most imaginative romances I’ve read for a long time. Thanks for that!

Cute enough

Simon's dad was actually my favorite. It was a pretty skimmable book. Not very spicy, if that's what you're looking for. It was way, way too long. I kept looking at the progress markers wondering if maybe she was going to start a sequel at the end, or if it was going to take some sort of crazy turn, like a death or bankruptcy, but no...marriage and pregnancy and babies and college...yeesh.

hilarious

Simon and Bella are absolutely a riot. They made me laugh out loud and also made me almost cry in parts.
What started as a stupid 1 month arrangement turned into a forever partnership of two complete opposites .
The whole story was captivating and thoroughly enjoyable .
Please make sure you read it, one of Sandi’s best.

A great story written for escapism.

Simon and Bella meet in unusual circumstances. I loved the banter between Mr serious that planned every moment of his life and Miss Spontaneous.

There was a couple of steamy moments with copious amounts of chemistry but the dialogue between the two was really funny.. Also Simon's dad was just has funny..

a little insta-love, a little too-good-to-be-true, and very fast-paced, but at 290 pages, that makes it an easy one- or two-sitting read. i wanted it to feel more like fall, but it gave me what i expected. it was nothing more, and only less in how quickly it moved. wouldn't not recommend, wouldn't run to recommend either.

cute

Very cute. I loved that it showed well into the future. Also, my first ultrasound at 8 weeks was the same and I legit had the same reaction as Bella. Our pregnancy also ended up the same if you know what I mean so that was relatable and very well written. Although I did end up pregnant again one kindergarten started lol. Very sweet story

Loved this story - great characters - good laughs, some teary moments and a fine romance. Sandi Lynn does this so well. I particularly like how she finishes her stories with no questions left unanswered unless they lead to a sequel.

Omg

Wow I loved this book. They started off as roommates. He wanted a quiet house. He got a woman who didn't talk his crap. The attraction grew and love followed. They were absolutely opposite of each other but perfect for each other. Great book
