This book seemed to be more about the locations and trying to be mysterious than romance. The MMCs were hot and very drool worthy however, Tessa was irritating in that she was so nosy and always putting herself in situations where she didn't belong. I just did not connect with this story.

Terrible nanny
Truth: I basically DNF’d because the FMC was nosy (not in a good way) and not a great nanny, which seems like it should have been a priority. Just not my favorite. . .

In Billionaire's Nanny, Tessa is a catering waitress. While working an event, she encounters Tabitha, a precocious 6 year old who is bored and seeking her own form of entertainment when left to entertain herself at her father's event. Taking the child under her wings and keeping her out of trouble, little does Tessa know that with that simple act, the trajectory of her life will forever be altered. Damian is Tabitha's father. He's wildly successful in the art world and a billionaire. Theo is his body guard and head of security, while Nico is his chauffeur (of any form of transportation that moves) and personal chef. The three travel everywhere together.
Damian is out to right the wrongs of the previous generations of his family. He wants his daughter to be proud of her legacy and he will do anything to ensure that she has this opportunity, even if it requires lying, stealing and riding the fine line between what is morally and legally right and wrong. In order to do this, he desperately needs the help of someone he trusts to watch over his daughter. Tabitha won't stop talking about Tessa and the time they spent together at the event. Without notice, Damian shows up on Tessa's doorstep and orders her to join them as Tabitha's nanny. Needing the money to help care for her siblings, Tessa agrees. What ensues is a quest for Tessa to learn who to trust. There is an air of mystery continually surrounding the three men that leaves Tessa feeling uneasy. Secretive meetings and phone calls. Continually jet setting from country to country. Locked vaults and rooms depicted on doll houses as nothing more than empty spaces. Who are these men? Are they good guys or bad? Tessa struggles with her growing feelings as she finds herself equally attracted to them all. As each man spends more time with Tessa and finds himself intrigued by her, each wants her for himself. These are three alpha males all vying for pole position in Tessa's heart. Little do they know, Tessa isn't interested in having only one in pole position. For her, it's all or nothing. Will they be able to give up ultimate control and learn to share?
Authors Sasha Moon and Cassie Cole have done it again! This is an extremely well developed novel. Normally I am quick to determine the plot and the direction it's taking. If there's a mystery in a plot, I've usually solved it by 25% of the way into the book. The plot of this book was hard to guess, which is actually what makes this book so fantastic! I love the twists and the turns; the hint at explanations without actually not explaining much of anything at all. LOL It kept me engrossed and wanting to know what the heck was going on. The authors did a fabulous job of slowly dispersing tidbits of plot weaving intrigue and mystery throughout the entire length of the book. This book kept me focused the entire time I was reading it.
I love that Tessa is a strong female lead. She isn't afraid to back down or ask questions when things don't make sense. She also has a soft side that just wants to be loved and to feel affection. She is like a mollusk, hard on the outside yet soft on the inside and in her heart. As much as she would like to trust, she has learned that you cannot blindly trust. So she asked questions. She watches. She tries to determine if her employer Damian is truly an individual that is upstanding and one whom she can trust with her life and her heart. The three men in the story are harder for the reader to get to know, especially Damian's character. The author slowly feeds you information with regards to their personalities, but even with the air of mystery surrounding them, there's something likeable about each of them. I couldn't help rooting for them all to get their HEA.
This book is an absolute definite must read!

This is the second book from this duo I’ve read. And I just can’t get into it. Like Cassie Cole books. Sasha Moon is new to me. This book has a decent storyline. Intrigue. Exotic places. Dangerous underworld. Tessa is plucked from her waitressing job to nanny for Damien. The billionaire art mogul and his 2 friends. They are deep into a new project that they call the Legacy Collection. She’s whisked around the world as she Nanny’s for the billionaire. My problem is that I just do not like Tessa. She’s quickly inserting herself into business she knows nothing about. Creeping around places she shouldn’t be and the billionaire and his security is okay about it. A slight talking to and that’s all. I like a strong female character, but she was often a brat. She just wasn’t likable to me. She was tolerable once they arrived in Greece, but I was too far gone at that point. Good level of spice. The scenes were hot. The guys were likable. Overall, I couldn’t wait to finish it but I found myself often putting off picking it up.

Author duo Sasha Moon and Cassie Cole delivered a well written reverse harem romance read in Billionaire's Nanny. Our female lead Tessa starts as a server at an event and meets a sweet lil girl Tabitha. Damian is Tabitha's father and after the event all he hears about it Tessa and so, in his billionaire style shows up unannounced to offer Tessa a job as Tabitha's nanny that she can't refuse. Damian may be the beginning but there is also Theo, head of security and Nico, chauffeur and chef. These three go everywhere together. I love how our authors introduce us to the art world, exotic places traveled. They weave together the heat and sweet so well and I love that there is a storyline with mystery, heart just as much as the heat the characters bring. A wonderful HEA is to be had as well! A really good read!

I absolutely loved reading this story about Tessa who meets Damien at a waitressing gig and meets his six year old daughter Theresa. She is surprised the next day when a helicopter arrives in the park across from her apartment and Damien knocks on her door and asked her to be his daughters nanny. Theo his bodyguard and Nico acts as his pilot and driver of anything mechanical and also his chef. Things become difficult and dangerous, and all three men are attracted to Tessa, and eventually start a relationship and the nanny gig turns into a permanent relationship, including all four. I loved the action and the intrigue and the little bit of danger that was in the story, but I also loved how Tessa worked away into everybody’s heart and they go on to have their happily ever after.

This book not only gives you a glimpse into the world of art but it also allows one experience the transition from one to three partners. Damien, Theo and Nico are currently trying to move through the art world and create their 'Legacy Collection' but they also have a six year old little girl in tow, Tabitha, who is soaking up every word and challenging them. Tessa is scraping by with her two roommates/ best friends in New York. A special event that she is a server at becomes the job interview she never seen coming. I enjoyed the story, getting to know the characters, loved their chemistry and how everything revolves around trust and loyalty. Enjoy!. I purchased the book as well for my library.

Heartwarming, Sexy, and Totally Addictive!
Billionaire’s Nanny by Cassie Cole is the perfect mix of heat, heart, and happily-ever-after. The chemistry between the heroine and her boss is off the charts, and I loved how the story balanced steamy moments with genuine emotion and family warmth. Cassie Cole always does a great job creating characters you can root for — strong, caring, and a little flawed in the best ways.
It’s the kind of book you pick up “just for a chapter” and end up finishing in one sitting. Sweet kids, a swoony billionaire, and a nanny who changes everything — what’s not to love?
Highly recommend if you enjoy spicy billionaire romances with heart and humor.

Job benefits aplenty
Billionaire's Nanny is a fun and entertaining RH romance by co-author's Cassie Cole and Sasha Moon. It finds Tessa, a catering waitress, working an event when she finds a sweet little girl named Tabitha. The event is being held by Damian, who is six year old Tabitha's single father. Tessa keeps Tabitha entertained and with that one kindness her world is about to get turned upside down. Tabitha tells her dad all about Tessa and since he is so obviously in need of a nanny he decides to find her and then offer her the job. But besides being a nanny Tessa quickly discovers the job is about to come with some other benefits, Theo the head of security and Nico the chef and chauffeur.

At 25%, I had to DNF. As some other reviewers mentioned Tessa is annoying AF.
She was constantly going into places that she was told not to go. And maybe if they had already established a relationship or she had been a nanny for a few months I’d let it slide because the curiosity built up. But literally the first or second day on the job she’s snooping where she was told not to. I’m sorry, did you WANT to lose your job that’s paying $1 million? That just seemed…stupid to be honest.
She does it again like a few days later. She’s caught both times. I just don’t think that someone who is literally so poor they can’t afford food, is so willing to risk this overly generous paying job. The stupidity was too much for me.
Also….she’s a shit nanny. And that’s the premise.

This joint venture reverse harem story was entertaining to read. Tessa our server meets a wayward little girl at the party held for Hawthorne Conservancy which leads her to be hired as her nanny. Loved our characters. Tabitha was a cutie. Our hotties: Damien, Theo, and Nico brought their own personalities into the relationship that develops with our nanny Tessa. Loved their interactions. The romance was hot. The story kept me captivated. This has all the wonderful things I'd enjoy from a Cassie Cole and Sasha Moon stories I've read. This is their second collaborated story the first is Lakehouse Nanny which I also highly recommend if you love reverse harem stories like I'd do.

As a server in a birthday party you would think that the birthday girl will not get lost in the chaos. Tessa helps Tabitha, the 6-year-old find her way back to her father. Somehow getting hired as the nanny was not her agenda or other bonuses she would later enjoy. Why choose when you have a billionaire, a chef/ valet and another one who likes to not be seen per se. They are different on so many other levels but meet in the middle somehow and that denominator is Tessa. Interesting situations that leads to steam it's simplistic or complicated as they may seem. Pretty good read.

I read this almost two months ago, and just realized I never posted the review here. In my defense, Booksprout still says the book's not available here. Anyway
Over all, I enjoyed this book. I do kind of wish more things the males reference were explained though. Like, even the "Ottoman auction" even was only vaguely explained, and I wanted to know what happened to Tabitha's mother
It's a relatively short read, and I finished it in two days (taking one day off for surgery). I'll definitely read this author again.

From Destitute to Decadent
Tessa goes from working three jobs to make ends meet to working as a nanny for billionaire Damien Voss Hawthorne. Along the way she meets pilot/driver/chef Nico and bodyguard Theo. The jet setting is beyond decadent, the intrigue is suitable mysterious and the heat is red hot. The story is not without its plot holes (nannying Tabitha seems like an afterthought too often - she’s left alone or sent off with others, Tessa’s New York friends are slowly forgotten and we never do loop back to her family), but overall, this book is a pretty great read.

Tessa's world changes from the mundane to the extravagant when she takes a nanny position that comes with a very active little girl and three men that takes their art world too serious. What starts out as a simple job turns into so much more leading to a relationship she never imagined. Will Tessa and her three men find their happiness. This thrilling story kept me glued to the pages.

Great Story!!
This was a great story however, it did seem a little short. Maybe a little rushed, but that could also be because I wanted a little more development of the characters as a family :).
Also, I love how this story doesn’t seem like there are two different authors! Whew :). I love that!!!
The only real criticism I have is that there are too many characters with names that start with the letter “T” and it makes reading the story a little confusing.

I liked this book. The storyline was nicely balanced with cuteness and heat. I thought all of the characters were likable and that the chemistry between them was potent. The addition of dama, steam, mystery and twists to this romance kept things interesting as things progressed.

interesting choices
So you are a billionaire with a daughter and you decide to hire someone you have met once to be a nanny. Yeah that’s going to work. But in fiction world it does, to an extent.
So many plot holes…

completely lost
I don’t know what I have just read but the main story was completely lost on me, the whole way through the book. The 4 main characters have good chemistry but what the child’s role within the story is, I have no idea.

DNF (~50%) I was liking the premise of this story, but it was continually ruined by Tessa. She was so nosy and kept recklessly sticking her nose into business that clearly wasn't for her to know. She was driving me insane.
November 22, 2025
Nice quick read. It's very well paced writing. Heart warming story. Excellent for a pallet cleanser. The spicy scenes are spicy.

This was a great read. There was drama and romance. Overall, it was a short, sweet read. Love these authors.

Too bored
I was not interested in the plot neither in the group together, Nico was the worst no chemestry at all too slow.
The first half I enjoyed but then was boring.

Suspense and sexy
An very interesting spice of sexy and suspense with quirky and funny dialog that brings out the best of each one.
Worth the read.

Tessa is thrown into a world of the wealthy when she helps a little girl find her father at a party she is a server at. The first half is the build up to the RH and the second half is the intense steam. I enjoyed the storyline and the spice but overall it just didn’t tick all of my boxes.
