Love is a Beautiful Feeling -
Rival CEO (Billionaire Secrets Book 1)
True Love Can Overcome Anything
This was a really interesting story about four friends who work together to not only try to become successful, but also want to ensure they are environmentally conscious whilst doing it. However, their path to achieving success doesn’t run smoothly, as they have to try to balance their professional and personal lives, as they find themselves having to make difficult choices. In addition, throw in a workplace relationship whilst living together made their lives a lot more complicated, but their determination to succeed and their hard work got them the results they wanted.
This was a truly invigorating story, that had me the edge of my seat as I eagerly turned the pages. Grab a copy of this book now and you won’t be disappointed. All I can say now is WOW, because if this is book one, then I am definitely looking forward to reading the next book in the series.
Bossy CEO (Billionaire Secrets Book 2)
Fighting the Inevitable
I was initially concerned when I saw the number of pages, but I can say without a shadow of doubt, that each page had a part to play in making the story a worthwhile reading experience. This captivating story had everything I expected in an Ainsley St Claire book, including angst, suspense, drama, steamy encounters, personal and professional sabotage, and a mystery that had me continuously trying to guess whether there was foul play involved or just plain betrayal.
I urge you to carve out an entire day free of any disruption before you start reading this book, because there is no chance you will want to take a break once you start. I think Ainsley St Claire may be on her way to be crowned the Queen of the Cliffhanger, as she leaves her readers itching to read the next book in the series urgently.
Grumpy CEO (Billionaire Secrets Book 3)
Being in the Right Place at the Right Time
OMG! I think Ainsley St Claire should definitely be nominated for ‘Queen of the Cliffhanger Award’, because each of her books take you on an an adventure filled with drama, secrets, betrayals, romance, amazing camaraderie and wonderful happily ever after, but it always leaves the reader craving to to read the next book in the series. I can tell you without a shadow of doubt, that this book is no exception in the way I was hooked on the story from the first page and didn’t take a break until I reached the end. Grab a copy of this book now and indulge yourself for a few uninterrupted hours of an amazing reading experience.
Player CEO (Billionaire Secrets Book 4)
Secrets and Lies Always Come to Light
OMG!. I thought books one and two were great, but I can say without a shadow of doubt, that book three was definitely on different level above the other two. I started reading the story hoping everything would turn out fine, but by the time I finished reading chapter eight, I was on tenterhooks and every single one of them became a suspect in my eyes. However, my decision changed when the evidence started coming in and was clearly directed at only one.The conclusion to the Justin saga was heartbreaking, but also wonderful as it led to a two people finally getting the happily ever after they deserved, after dealing with so many obstacles in their lives.
It took me the whole day to read this book, but by the time I finished reading it, I felt like I had just been on a rollercoaster ride and came back to be chased by a coalition of cheetahs. I urge you to read books one to three before reading book four and I highly recommend you make sure your entire day is free from disruption, before you devour this fantastic book. In my humble opinion, Ainsley St Claire has definitely hit it out of the park with the Billionaire Secrets series and has left me looking forward to reading the next series.
I read each book in the boxset individually as part of the advanced review team and I absolutely loved all of them. If you are looking for your next weekend read or vacation indulgence, then grab a copy of this collection of amazing books and entertain yourself.

This is one of my all time favorite authors and series. Each book follows one of the men behind EnergiFushion as they deal with their business partners disappearance and new relationships. This is one of those series that will have you on the edge of your seat while laughing and crying. I can’t wait to see what Ainsley has in store for us next. 🖤🔥🪫🔥🖤

This book series.. I didn’t expect much going into it, I’ll be honest. I expected light, sexy, billionaire stories that connected. I was very surprised in the best way with the drama, suspense, character development, and how it ended. It has left me feeling countless things and I cannot wait to read what else this author has done.
