My Big, Fat, Accidental Billionaire Husband

by Catto Love

A Standalone Vegas Wedding, Billionaire Romance (with a ripped bikini top)

First rule of Vegas Girls' Avoid accidentally marrying your boss's insanely hot, notoriously commitment-phobic billionaire friend.

My Vegas "let loose" weekend started with a mortifying poolside encounter involving billionaire Dominic Rossi and a ripped bikini top.

One ridiculous dare and several hazy, high-octane hours later? I wake up in a strange penthouse suite with a pounding headache, a gold band on my left ring finger, and the intensely gorgeous, equally horrified Dominic beside me.

Annulment is the obvious, immediate plan.

Until the tabloids plaster blurry photos of our 'nuptials' everywhere, threatening to derail his $1.5 billion resort deal.

Suddenly, Mr. Control-Freak-Commitment-Phobe needs me.

His Stay married for exactly 30 days. Save his empire, get a payout. Simple, right?

Now I'm living in his stunning penthouse in NYC, trying to maintain my professional composure while navigating the undeniable heat simmering between us. He's chaos to my carefully constructed order, haunted by shadows I don't understand, and infuriatingly capable of seeing straight through my defenses.

After being spectacularly left at the altar before, letting anyone close feels like tempting fate. This arrangement is purely transactional. Getting tangled up emotionally with my temporary, accidental husband? That's a complication my organized mind refuses to allow.

So why does fighting with him feel like foreplay, and why is pretending to be his wife starting to feel dangerously real?

My Big, Fat, Accidental Billionaire Husband is an entertaining contemporary romance that finds its lead protagonist Tatiana in Vegas with her besties celebrating one of the groups recent promotion.
Who should she spot by the hotel pool, non other than her bosses friend billionaire Dominic Rossi, there celebrating a friends upcoming wedding.
Avoiding him becomes impossible after an accidental trip has Tatiana climbing his legs to stand up then loosing her bikini top in the process.
She and her friends are then invited to Dominic’s party and the one thing I didn’t like was the designer drug they got talked into using by one of Dominic’s friends.
The effect along with their alcohol consumption, unfortunately or not has Dominic and always professional on Tatiana ending up in a quickie Vegas wedding.
In this case what happens in Vegas doesn’t stay there.
The next day they wake to find out the billionaires marriage faux pas is all over the news. With a big deal on the line Tatiana agrees to a thirty day reprieve before the marriage is annulled, just until his deal goes through. But of course they now have to live together to keep things on the up and up, and the count down begins.
Whoosh there is a lot to unpack in this story but it was an enjoyable one because they may have married for the wrong reasons but the attraction was definitely there.
Tagging along as they reached that epiphany themselves was fun, though not communicating those feelings mixed in some drama, family secrets, personal vulnerabilities, and emotion to a nicely written and crafted story. HEA.

She is in Vegas celebrating with friends, when she runs into her bosses best friend, and they join his party. They unwind a little and the next thing she knows she wakes up in his room with his ring on her finger. They think they will be able to get a quickie annulment until it hits the news because her new husband is a billionaire with a deal on the line. She agrees to hold off on the annulment so he can finish his deal...but they have to live together so everything looks on the up and up. Of course once they are living together it gets harder to ignore the attraction they have for each other, and the lines become blurred. Things get hot and steamy for them, as they try to figure out what they are. The author has a great writing style with lots of humor that adds to the character development. They are engaging, have strong attraction and are a little bit flawed. Finding love when you least expect it. Getting a happily ever after you never saw coming, it is always an adventure and worth the ride.

This was my first time reading the author and I was immediately hooked to her writing. The characters were great and perfectly suited. The narrative structure also cleverly let us see them meet when they were more open, joyful and free of their emotional baggage. You catch glimpse of the secondary characters which gets you invested and intrigued in the overall series. The plot was simple, but engaging. The writing had humour, great dialogue and flowed well. There were some elements that were difficult and frustrating to read but worked with the plot and perhaps the forgiveness at the end was a little too immediate, however it was clear that long term changes and work to change was being done, so that's only a tiny issue. Overall I really enjoyed and was captivated by this love story and am looking to read the others in the series.

This is book 3 in Love's Big Fat Bigwigs series and can be read as a standalone. I've enjoyed each of the previous books in this series and we get just a tease of who our main characters will be in the next and here we have Dominic and Tatiana. I love these two opposites. These two have great banter as well as chemistry and I love how we have a great balance of both sweet and heat. A smooth flowing and captivating storyline. I just so enjoyed these two and the overall development as the read progressed. A great read and I'm looking forward to more from Love!

Very, very good

I couldn't put it down at times, but having to because of something else! The whole story was quite interesting and intriguing!
Even though there was a Episode that was included, I had to put the story away. Then I couldn't get the Free Special Episode the next day to try and continue the story of how the concluding characters did certain things!
So I had to go ahead and start reading the next book. To continue the story that way!
It's still a very good story.
I wish that I could go ahead and read the Continuing Special Episode. But since I can't get it to play, I'll continue with the next book!

Tatiana and Dominic

Such a beautiful story. They had a rough start, but it together and made a life with each other and then a baby. Such a great happily ever after.

Billionaire books

This is the 2nd book in the series I read both in one week.
The story lines keep you glued in until the end.

While not a traditional love story I actually enjoyed Dom & Tatiana’s tale to their happy ever after. It had ups and downs and some spice as well.

DNF: I don’t date man-children, even in fiction

Honestly, I should’ve quit in chapter 2 when everyone casually took GHB like it was normal—that was insane. Dom was unbearable the entire time: hot and cold, immature, and constantly playing with Tatiana’s feelings. And the cherry on top? He actually told his brother that after the contract was up, he’d “set them up.” He keeps saying he feels guilty, worrying she’ll hate him when she finds out… but still strings her along. Still intends to set them up. Sir, please.

Tatiana was supposed to have a backbone, but instead she let him treat her like trash, and we’re supposed to believe they fell in love in under 30 days? Add in sloppy continuity errors and nonsense subplots, and I finally tapped out. DNF.
