4.4 out of 5 stars 12,037 ratings

From New York Times Bestseller and BookTok sensation Rina Kent comes a captivating age-gap billionaire romance filled with power, desire, and betrayal.


Nothing is fair in war.

Jonathan King is every bit his last name.
Powerful. Untouchable. Corrupted.
He’s also my dead sister’s husband and way older than me.
When I first met him as a clueless child, I thought he was a god.
Now, I have to confront that god to protect my business from his ruthless grip.
Little did I know that declaring a war on the king will cost me everything.
When Jonathan covets something, he doesn’t only win, he conquers.
Now, he has his sights on me.
He wants to consume not only my body, but also my heart and my soul.
I fight, but there’s no escaping the king in his kingdom...

Reign of a King is the first part of a duet.

    My first book by this author. I think it's a slow start but getting more gripping as you get into it. I loved all of the characters and the story line. It is very well written and entertaining.

    I flew through this book as it was so good.

    I knew there was always some underlying mystery with the characters and boy was I right. Well, I don’t know how much yet but after the ending, there’s a whole load of stuff to be unraveled.

    Really great book.

    5.0 out of 5 stars Her books just get better!!
    Reviewed in the United Kingdom on 1 July 2022
    Format: Kindle EditionVerified Purchase
    As the title suggests, Rina's books just keep getting better than the one before it. I
    I started with Cruel King and followed the books from there!!
    Just when you think....
    "Yeah it won't get any better than this, there's no way she can do it again!!"
    That's your thought process and an assumption quickly dispelled, the second you start on her next book, within the RES world, and now following on with Jonathan and Aurora!!
    After all she's dealt such sensitive issues, through the RES world and did so with such grace, forethought, empathy and above all, extreme care and due sensitivity, that surely there cannot be anything else with which to tackle in such an intense manner!! BUT if you too thought that, then I'm afraid, we were both wrong!!
    This book...yes this must be about the fourth time in saying this...is definitely her best work yet!!
    The passion is there undoubtedly, yet it's the undercurrent of the story line, that packs the pages with a monumental size punch, and it's a punch you'll be glad to receive!!
    If you want a mediocre book, then I'm afraid this book is NOT for you. But if you want a book that you'll read in one sitting...and then, begrudgingly have to take a quick break from the next book so as to do the review....then trust me friend, this book IS for you!!
    As my friend would say....

    overall i liked it. the only issue i have was that johnathon was a bit too domineering for me/controlling. even though aurora stood up for herself most of the time it was a tad bit off putting. it lacked build up and connection before the smut started. but the flow and style of writing was good. i would get the next book to see what happens.

    'When Jonathan covets something, he doesn’t only win, he conquers.
    Now, he has his sights on me.
    He wants to consume not only my body, but also my heart and my soul.'

    Reign of a King is the first book in Rina Kent's Kingdom Duet.
    It's a Dark Romance based in the King's World.
    Johnathan is Aiden's Dad from the Royal Elite Series and features in their books too.

    Aurora is determined to save her company, she goes to a wedding with a friend and unexpectedly bumps into Johnathan King-Her dead sister's husband!! Johnathan goes after her and becomes involved in her business. Aurora is hiding from her past and trying to find out what happened to her sister. Shocking secrets are exposed that leave her reeling and scared, all the while having to deal with Johnathan and his 'ways.'

    The plot was captivating, pulling you into the King's world, a world I didn't want to leave.
    Johnathan is for sure my favorite, an alpha male who is a business tycoon and isn't afraid to go after what he wants.

    If you like Dark Romance, then this is for you. A plot full of mystery, spice, and secrets.

    1.0 out of 5 stars Spank you!
    Reviewed in the Netherlands on 4 September 2024

    Spanking, spanking and spanking. It was TOO MUCH that I had to skip these parts. Aurora is a typical character, deluded…she thinks she doesn’t, have choice in the matter but to get laid by her brother in law. Lacks dignity, self pride and self respect. Jonathan just likes to spank.

    I expected more but this was disappointing.

    ⭐ 3,25/5

    I was very curious to read Jonathan King's story after his brief appearances in the Royal Elite series books. His personality makes you curious about him and I was really looking forward to starting his bilogy, but it wasn't what I expected.
    Don't get me wrong it's not a bad book, I really don't think there's a RK book I won't like but after reading the Royal Elite series this book felt very basic and lacking a lot of substance.

    I thought that since it wasn't a single book, the relationship between Aurora and Jonathan was going to progress more slowly and that it wasn't going to be so sexual, something that for the first time in a long time I didn't like very much.

    Then, Jonathan's personality, he is so alpha male but not in a good way really, I like MMCs that are possessive but he is too ‘Aurora, my property, my body, unga unga’. And I do not know how I feel about the dob-sum relationship they have, there is something that doesn't sit quite well with me.
    I'm really more intrigued by the part of the plot involving the mysterious tapes Aurora receives and everything that happened in her past than I am with the love story between her and Jonathan.

    Then there's the fact that Aurora is the younger sister of Alicia, Jonathan's former wife and Aiden's mother, and to top it all, she's dead. It seems a bit strange to me.

    Although there were quite a few things that didn't meet my expectations, it's still a book that I enjoyed reading and I had a good time, I'm looking forward to find out what happens in the second one.
