Hidden Secrets

Billionaire Boss #3

by Lisa M. Miller

I’ve been in love with Kate ever since she walked into my bar six years ago, needing a job to help her through college. Unfortunately for Kate, bad things happen to the women I love but even this isn’t enough for me to keep my distance. I’ve not been able to get our night in Vegas out of my head and I’m done tormenting us both. Like I need my next breath, I need Kate.

Mike is my boss. My super broody, handsome boss. The guy gets me on so many levels, right down to the kinky stuff. He’s given me every opportunity since I started working for him. I’m his right hand. He depends on me for so much. Why will he not let me incompletely? Into his bed. Into his heart.

Whoa!!! I truly enjoyed reading this book with 5 sub characters from previous publications, which meant I'll be purchasing the ebook soon. This 3rd book from Billionaire Boss series can be read as a standalone. It's steamy, with dominant BDSM tendencies but Kate's character is strong, independent, sexy yet submissive to Mike.
Mike, who has unresolved issues, therefore was unable, unwilling to start a relationship with Kate, who is 18years younger but it all ends well.
I love how the author inserted the incidents from 6 years ago in the ending chapters and it blended well. Highly recommend this book if you're good with some BDSM.

In this last book of the Billionaire Boss Series we have Mike and Kate. These two have worked together for years in different clubs that Mike owned. In a previous book Mike and Kate hooked up. Mike then made it clear to Kate that it wouldn’t happen again. Mike decides to open a sex club and Kate says she wants to be a partner. As they work on opening this place they become closer and Mike finally decides to give in. It was so clear and obvious that they loved each other but Mike had demons he needed to deal with first. I loved how honest Kate was with Mike, telling him either we are going to happen or you have to let me go. Really great book with a couple who were honest and real with each other. Will Mike eradicate all his demons or will some linger and destroy their relationship?

This book revolves around Kate and Mike who have an 18 year age gap as well as a boss/ worker relationship that makes things rough for them at the start but once they move past that their relationship is allowed to blossom. From that point the book becomes fast paced and sexy.

Hidden Secrets was my first read by Lisa M. Miller and it definitely won't be my last. I really enjoyed reading Mike and Kate's story and the journey took to get to their HEA. The chemistry between them was off the charts hot. They spent an amazing night together but demons from Mike's past threaten to keep them apart. Definitely recommend this story.

This book is a wonderful grumpy sunshine, boss-employee, dom/sub trops. After over coming a troubling past romance and business follows. This is definitely worth a read.

Absolutely loved Kate and Mike x

Kate is so bad ass and just the right level of sass to keep Mike in check.

Mike is a broken man but wants to be the best for Kate x

This friendship group is just goals and just adds to the individual stories x

Great book x

18-year age gap
Friends to lovers
Past trauma
D/s

This book had all the spicy scenes and a touch of a D/s dynamic. Mike and Kate are fighting their attraction to each other as they embark on a new business venture. Things get heated and they can't keep their hands off of each other. The chemistry throughout the book is hot. One thing I wish there was more of, is more of a story. I felt the last few chapters rushed to the end. I would have liked the relationship to play out a bit more before the ending. I would still recommend this to anyone if you are looking for hot friends to lovers with off-the-chart chemistry.
