It starts with a sext to the wrong number

This is a great, well written, entertaining story. With an ex's older brother office romance, family drama, brilliant character chemistry, triplet surprises, banter, twists, romance and love.

When Mona sends a text to the number the guy at the bar gave her, she didn't mean to send her sext to a wrong number or expect him to reply, but after their messaging gets heated they agree to meet and pick up where the messages were heading.

But realising the one she's been chatting to is her boss is embarrassing, finding out he's her ex's older brother is worse; but they can't stop texting each other or keep their hands off each other when they're alone.

When Mona's then framed and made a scapegoat for corruption in the office, Deck knows he needs to work to help clear her name.

What a read! This book is full of intrigue, plenty of dry humor that totally works, friendships that don't waiver and a love that grows from mistaken identity!
Ms. James has, once again, given us a story that is extremely difficult to put down once you start. Her characters are intense, yet giving. The plot is full of plenty of stops and go's that keep you on the edge of your seat, digging in just enough, giving just the right amount of insight to make the reader think they know what's going to happen next, only to deviate and make you second-guess your choices.
Mona and Deck will keep you on your toes as they navigate not only their way to justice, but to a love that will have your heart thumping irregularly, one beat at a time.
Very well written and a definite must read!.

I really liked this book. Mona texts Deck by mistake some sexy content she meant for someone else. He took it and ran with it. Eventually, they met and had chemistry that was super hot. There was a lot of drama around Deck and Mona and who she worked for that was a little complicated but it finally got resolved. The story had some surprises, misunderstandings and throughout all of it, he supported her completely. It was really a very good story.

OMG I have never laughed so hard like I did when I read the very first chapter of this book by Summer. When Mona accidentally sex texts someone by accident her actions is hilarious, but don’t worry things will definitely heat up.
This is a 10-star hot romance book that will have you sitting on the couch and swooning over Deck. The intense heat will make your body tremble with excitement while reading what I say is the most exciting and amazing romance story ever. Hot and Sexy cover plus the characters are Hotter. Summer delivers a phenomenal romance story that you need to read now.

Just Couldn't Get Into This Book

The writing was very choppy, with no fluidity to the storyline. Think undulating waves on a calm ocean or sea. Fluidity. There were lines tossed in with the dialogue exchanges that were nothing more than something to fill in the gaps. And the single word responses didn't help. That, too, added to the choppy writing. So, I decided to give up. I've had less trouble reading and understanding time and space, along with Einstein's relativity (E=MC-squared; the speed of light).

[Mindy · Rating 4 out of 5]

This is a Book in the Billionaire Ex Appeal Series by this author, and can be read as a standalone. It is an age gap, off limits, workplace romance between Mona and her ex's older brother, Deck. These flawed but likeable characters and the unique plot makes for an interesting read. It is a love story with drama and steam, sexual tension and chemistry, humor and charm, suspense and intrigue, and twists and turns, plus appealing secondary characters. Quite a page turner.

Sending a sext to the wrong person can be embarrassing enough but this is next level. This book has a little of everything. Deck and Mona have off the charts chemistry, it brings a lot of sizzle to the storyline. There is good drama and lot of misunderstandings but the one consistent is the support that Deck gives Mona. This is such a great read.

I wont lie, I was a bit skeptical when I started. Just took me a bit to get into the story. Once I got past that though, I was hooked. There's drama. There suspense. There's love and the greatest HEA ever. I really did LOL, had a bit of tears forming in my eyes, and swooned at the love being built. Wasn't sure if this was going to keep my interest, but it surpassed all expectations and I couldn't stop.

I really like this book. The story goes back and forth between the FMCs point of view and the MMCs point of view. They find each other through a sexy text sent to a wrong number. The spicy is spicy. And the HEA includes triplets.

Scandal Comes Crashing

Deck and Mona connect one evening, not knowing they have a shared past. When it comes to light things between them change, just as corporate scandals try to push them apart. It was entertaining and steamy as Mona and Deck try to survive the outcome of it all.

I enjoyed reading this book. Unlike others with this theme, we don’t find out until much later that Deck is her ex’s brother. They had the same last name so how was that going to work out. It also had a much bigger plot than I was expecting. Well written with wonderful characters and great steam.

[Summer Stanley · Rating 4 out of 5]

The story is good and Mona is humorously relatable. The kind of awkward most of us are but pretend not to be. It's definitely got a lot of drama and depth. Bonus is all the spice in it.
