Not for me

"Daddy Kink" is not for me. Unfortunately I stuck it through. I didn't even feel the connection between the two. I need more about the sisters and their Father.

College student Penny and billionaire Wilder have one thing in common: Love is nowhere on their agendas. Penny needs cash to help her sisters out of a bad home life; Wilder needs to feel something real, something new he can observe and be challenged by. They strike a deal — Penny will spend a weekend with Wilder, giving him her v-card and her authentic self in exchange for $4 million. What was supposed to be a simple business transaction becomes less and less simple the longer they’re in each other’s company, but are the emotions being stirred up actually real?

This book was a surprising departure from most of the books I’ve read from Khloe. I still got the heat 🔥, the dominant alpha male 🫠 and the satisfying HEA (and accompanying epilogue), but what I didn’t get was the usual instalove trope. Neither Penny nor Wilder had the “eyes meet and they know they’ve met The One” moment, and their meet cute was him buying her off the internet. While v-card auctions are not an uncommon plot point in the genre, Wilder didn’t experience the immediate bone-deep instinct to protect Penny from the world that typically occurs in these situations. However, I’m not suggesting that the book was inferior for not following those norms. It still provided the best bits of instalove — the heat and the sweet, the dirty and the devoted, the filthy and the fun.

Let me be honest: I went into this book expecting heat and high drama. And yes—it delivered that in spades. But what I didn’t expect was the emotional depth underneath all that sizzle.

Wilder Stone is a billionaire who’s used to getting what he wants. So when he see's Penny's profile on the virgin auction, vulnerable yet fierce, he knows she’s different. He doesn’t just want a night—he needs to know her. All of her. And Penny… oh, Penny. She broke my heart and stitched it back together. She's not naive or helpless—she’s brave. Sacrificing her dignity for a weekend with a stranger so she can save her younger sisters from their abusive father? That’s not weakness. That’s strength.

Their attraction is instant and undeniable, but what makes this story shine is how they both carry secrets—fears, doubts, hopes—and how the act of choosing to share those pieces becomes the foundation of something real. Wilder’s transformation from controlled and closed-off to fiercely protective and emotionally vulnerable? Goosebumps. Absolute goosebumps.

And when Penny’s sister calls in a moment of danger, Wilder doesn’t hesitate. That’s the moment this stopped being a story about lust and became a story about love—raw, messy, beautiful love.

Khloe Summers does something rare here—she wraps emotional honesty in silk sheets and champagne flutes, crafting a love story where power isn't about money or control, but about showing up, standing strong, and choosing each other—even when it’s scary.

Perfect for readers who crave:
💰 Billionaires with emotional depth
🔥 Forced proximity with heart
🛑 Angst with a dash of hope
👧🏽 Strong women who fight for their families
❤️ A man who realizes too late that love is everything—and fights to earn it

If you love a story where love grows out of vulnerability, where strength looks like trust, and where happy endings are fiercely fought for, Marked by the Billionaire will absolutely mark you too.

Intense, Addictive, and Surprisingly Tender!!!

Marked by the Billionaire is precisely what I look for in a quick, high-heat romance: strong characters, explosive chemistry, and a storyline that balances raw passion with genuine emotion. Khloe Summers delivers another powerful installment in the Rugged Mountain Ink series, and Penny and Wilder’s story had me hooked from the very first chapter.

Penny’s decision to sacrifice everything for her sisters immediately gave me someone to root for—she’s vulnerable but never weak, and her resilience makes her a heroine worth cheering on. Wilder, on the other hand, is gruff, inked, and used to getting exactly what he wants. Their dynamic is intense, but what made this story shine for me is the way Wilder’s protective side slowly chips away at Penny’s walls, transforming possession into something more profound.

What stood out:
💎 A fierce, selfless heroine willing to risk everything for family
🖤 A dominant, tattooed billionaire who’s both commanding and protective
🔥 Instant chemistry that builds into heartfelt connection
🏔️ Rugged mountain vibes with a luxury twist
💖 A guaranteed HEA that leaves you smiling

This novella is perfect for fans of possessive heroes, age-gap romance, and high-stakes emotional drama. It’s short enough to devour in one sitting, but powerful enough to stay with you after you’ve turned the last page.

If you want a steamy escape that mixes grit, ink, and a whole lot of heart, Marked by the Billionaire is a must-read.

"... love isn't weakness. It's power ..."

Marked by the Billionaire is the second book in the Inked and Possessive. Rugged Mountain Ink series. This story is about Penny and Wilder. I will mention that if you are not into a DDlg kink that this story will most likely not be for you. Penny needs money quickly so that she can take her two younger sister away from their abusive father. She already works multiple jobs and goes to school full time so the only way to accomplish this is to auction her virginity. It may not be the ideal thing to do but she has her reasons and that is all that matters. Wilder is a billionaire who lives and works out of Miami. He has grown bored and unfeeling because of his privilege and that everyone around him always does and says what he wants them to. He longs for a new experience and buying a virgin may just be what he is looking for. Thus Penny and Wilder meet at the local Fall-Fest to establish the rules and then go from there. Let's just say that this story is quirky, sometimes was a bit harder to follow, completely OTT and a fun read.

This was a good book but there were a few things that bothered me….

Things I liked
- I love that he falls pretty fast and is OTT
- Reynold is great
- I love the found family for him with Penny and her sisters
- I did like the ending.
- The sex scenes were pretty good, but see below.

Things that bugged me
- I don’t get the title, I don’t see how he marked her.
- I feel like the sex scenes lacked enough descriptors of him, it’s mentioned that he’s inked and big and the cover supports that but the author doesn’t elaborate on that, a lost opportunity if you ask me.
- seemed like a lot of things could have been fleshed out much better.

Penny and Wilder

Marked by the Billionaire is Book 2 of the Inked and Possessive. Rugged Mountain Ink series.  It's a short and steamy, virgin auction, age-gap, instalust to love, forced-proximity, DDlg, opposites-attract,  curvy virgin gets her billionaire mountain man romance. Penny is a 21-year-old sweet and curvy girl who is auctioning off her virginity to help her family. Wilder is a hunky, inked billionaire who won her. He wants to feel something real and is attracted to Penny. When he makes her an offer she can't refuse, both realize their feelings are very real. I loved this couple. Wilder just wanted to take care of Penny and her family, and she deserved to have a partner to lean on. Their chemistry was insane and the ending was so happy. I loved it.

This story is pure fire from start to finish. Sloane is selfless and brave, doing something unthinkable to protect her sisters, and Wilder is the gruff, inked billionaire who surprises both her and himself when he claims her. What I loved most is that beneath his commanding, protective exterior, Wilder truly sees her worth and gives her the safety she’s been missing. Their chemistry is instant and intense, and the age gap dynamic makes every interaction even more addictive.

It’s steamy, a little over-the-top in the best way, and delivers exactly what you want in a quick, high-heat romance—possessive hero, curvy heroine, and a happily-ever-after that leaves you smiling. 🖤🔥.

Perfect!

The best thing about Khloe Summer's books is you get a full story, without having to spend 2 days or more reading, to get to any pivotal parts, and no complications with cheating, and heartbreak. That is always in the background history of the characters. Penny had a full load of responsibilities, since her Mother died, and her Father crawled into a bottle, and became abusive to her, and now her 2 younger sisters. Wilder bought a Virgin at an auction because he was empty, and looking for something. He just didn't know what. He is immediately drawn to her open honesty, and responds to her need for a protector. Wonderful HEA ending, for them all! Trish. A.

I received this book with the understanding that I could leave a voluntary and honest review.

In this book we meet Penny & Wilder. When this book opens we find that Penny is meeting Wilder for a business transaction. What she didn't plan on was the draw she feels for him. Wilder finds it had to meet a woman who isn't looking at him with dollar signs in her eyes. That's why this arrangement is perfect. The problem is one look at her and he wants more. Can they find a HEA or will the past be to much to overcome?

Another amazing hit by this author. I would highly recommend it to anyone

Wilder has everything money can buy. He buys Penny at an auction, she needs money and he wants her innocence. When he negotiates for a weekend with her, he had no idea what was in store for him. I have enjoyed this series and each book has wonderful characters and the plot is always great. I can’t wait for book three.

Penny finds herself auctioning her virginity to keep her sisters safe. Wilder is a man who is slightly wild and he buys Penny, having negotiated a weekend with her.
Their time together is more than of sex, as Penny and innocents get under the skin of Wilder. The wild man finds himself falling her.
This is a fast and sexy read, with strong, possessive and emotional characters.

The eccentric, older, billionaire Wilder is looking for something real and innocent in his life. Penny is working three jobs and going to college full time to help her sisters escape their drunk dad. She decides to sell her virginity to make some quick money. Wilder finds Penny a challenge and develops protector instincts almost immediately. Can two people make a good laugh that started off with a virginity auction?

Penny is desperate to save her sisters so she auctions her virginity on a website. Wilder wants to experience something besides business so he buys her virginity. Discover how what starts as a transaction morphs into something more. I loved this short book! The characters were real and it went in directions I didn't expect which I thoroughly enjoyed.

Penny will do anything to protect her sisters, including signing herself up for a virgin auction. Penny captures the attention of Wilder Stone, he is used to getting what he wants and he wants her. There is something about her is different and he does not think one night will be enough. The more he hears of her story the more involved he becomes.

Wilder takes protection to another level when her sisters need help.

The author has given us an older man/younger woman story that pulls us into the lives of Penny and Wilder. The heartwarming story keeps us turning the pages with buying an experience, connection, giving in to unknown feelings and steam.

Penny would do anything for her sisters, and when they need money she decides to auction of her vcard. Wilders life as a billionaire has lost more than just its sparkle, but it soon reignites when he spots Penny, he doesnt do love but hell claim her for one weekend, but will it be enough for either of them? Well written steamy fast paced age gap desires and more.
