The Tycoon

Rate this book
I’m the perfect southern gentleman. Wealthy, handsome, charming…I’m the devil your Mama warned you about, and the knight in shining armor you wished for.

But beneath my alluring facade lies a demanding, bloodthirsty beast. Unable to stop its vile craving, my family has found a way to profit from it. For years now, things have run like a well oiled machine. I feed the ravenous beast, my family’s wealth and influence grows. It truly is a perfect arrangement. Or should I say, it was. Everything turned upside down the moment a sweet little blonde by the name of Dolly Dixon entered my life.

With our love and future in jeopardy, will my Princess accept my darkness? Am I strong enough to permanently silence the beast? Can I find a way to escape the corrupt underbelly of society without losing everything my family has worked so hard to achieve?

Well, I suppose we’re about to find out.

🔥Age Gap
🔥Dual First Person POV

I love a morally grey mmc especially when he’s a total golden retriever for the fmc. Sutton and Daisy meet on a dating app. It is obsession from first sight for Sutton and decides he can’t go through with his original plan for her. Instead, he’s going to keep her. You see Sutton isn’t your average Billioniare bachelor, he and his family unalive people and sell their organs on the black market. He uses the dating app to find women. Daisy is finally settling into living in Dallas, working as a librarian. She’s sweet but strong, and her confidence grows throughout with the help of Sutton’s devotion. This man is what dreams are made of, but without the unaliving. Sutton has to hide his dark side from Daisy, so she falls in love with him before he tells her the truth. The spice starts with a sizzle that very quickly catches fire and doesn’t let up. Daisy feels like she’s known him her whole life and knows right away she’ll marry him. Their instant and obsessive love made for a fast paced romance. He does everything he can to spoil her, including buying all the books on her wish list. Their relationship is Dom/Sub, but he’s so gone for her, so punishment for her bratty behavior is usually more of a reward. I look forward to reading more about the Douglas brothers.

A Few Favorite Quotes:
“I swear he’s five of my book boyfriends rolled into one real, live man.”

“No man has ever made me feel this desirable, or this special. I swear Sutton Douglas is too good to be true.”

“Princess... God has no place here. If you need to pray, pray to me. I’m the only one who can take you to heaven,” he growls.”

“Every book that was on your wishlist is in these boxes. You only had fifty of them on there, I wanted to get you more. So, what you’re going to do is make me a whole new wishlist. I want you to put every book you’ve always wanted on it. I don’t care how old, or what edition. If you’ve ever wanted it, add it. If the authors are still breathing, I will do whatever I have to to get them signed and personalized. We’re going to make sure our home has a library just for you,”

Y'all! Summer Riley is pulling all the punches with her first book in 1st POV! I was blessed to be an arc/beta reader for her and was blown away with these characters.

Dolly Dixon is one of us. Middle class family, raised in the church, a librarian, and a woman looking for love.

Sutton Douglas isn't any of that. Born with a silver spoon, works in his family's business, morally gray all around, and only looking for the next warm... body to be inside.

She turns his world upside down! I absolutely love the way Sutton falls so hard for Dolly from their first date. She is his. Imagine you're on a rollercoaster that just keeps going up and up... that's the rollercoaster ride Dolly is on. While it impossibly feels too good to be real, I love when the world starts to come down around them.

From Sutton's struggle with his dark side and keeping up the family business to Dolly questioning his promise of forever. These two make an amazing couple. The spicy scenes are incredible especially with his reassuring words when she is insecure about her inexperience... you're gonna need a fan!

I promise you are going to laugh, have your heart in your throat, see the darkest parts of a serial una!vër, and feel the love between Sutton and Dolly.

This is a good dark romance novella. If you want a read that is a little less than 300pgs I would recommend this. We have a sweet fmc and an ott unhinged protective mmc with a real dark side that runs in his family. At the end she has to choose between her morals or the love of her life. Please as always read your tw before reading.

I love you Dolly. Fiercely, uncontrollably. Undeniably. I am yours till my last breath 🥵🥵🥵

After loving Mine and Ours, I went into this with super high expectations and it did not let me down! Such an easy read but it had me hooked all the way through to the last chapter. I’m seriously hoping there’s going to be a follow up because I need more!

I really wanted to like this book. The triggers and stuff didn't bother me ...

It was the characters.

The sub/Dom relationship, uh.. there was no safeword

I felt like there was no real chemistry. Dolly felt, in a sense, childlike and then turned around and acted cutesy.... I understand the dynamics, but it was much more than that..
Maybe if she had just expanded more on her
character.


Sutton felt like he was the sub to his mother, more the actual Dom.

Things he said like , "Yes, Mama." His mother treated him like a child, not the grown man he was supposed to be.

It also never did explain for his sudden moments of him being in a paralyzed awakened state. ..It kinda felt off.

Maybe if she had expanded their story more, it would have made more sense.
Even at the end, he basically gave her an ultimatum.Yes ot No?? or !!!!!???😬💀

He's the madman dom and she's the sweet sub who just wants to be loved and oh does he love!

He will make her, his everything, luckily she let's him.

He has a dark secret that makes things complicated, family and political ties that are unhinged

This is Book 1 in the Douglas Brothers series and i cant wait to see what the other brothers are like and I'm sure I'll love them just as much as I love Sutton

This was such an interesting book. It dark and twisted🙈🙊 (Summer you did it again😋). The story is quite short, easy to read and it feels somehow as a psychological thriller. It's well written and has some action too. I do love Sutton's way (b@d boy). He gives spice to the book (3/5🌶).
This is for all readers who enjoy a fast paced short book with a hint of danger.
Love💖💓💕

ARC Review | Tycoon by Summer Riley

Summer Riley has done it again. Tycoon is a twisted, sexy, and utterly addictive deep dive into the mind of a man who was never meant to fall in love—and the soft-hearted librarian who brings him to his knees.

Sutton Douglas is dangerous, dominant, and deeply deranged… but when he meets Dolly Dixon, all bets are off. She’s innocence wrapped in temptation—everything he never knew he craved—and she might just be the one thing that saves him from himself.

Dolly is the kind of heroine you want to wrap in a blanket and hand a knife to. Sweet but not naive, submissive but never spineless—she’s the perfect match for Sutton’s brand of darkness. And whew, when these two finally collide? It’s fire.

This book delivers:
🖤 A morally gray antihero with a violent streak and a need to protect
🖤 A cinnamon roll heroine with submissive dreams and a backbone
🖤 Obsession, bloodshed, mind-melting spice, and a twisted found family
🖤 One hell of a satisfying HEA

Riley balances danger and devotion like a scalpel—and Tycoon cuts deep. If you love obsessive love, dominant MMCs, and a little organ-harvesting chaos with your romance… this one’s for you

Dolly's life has been marred by a string of bad relationships, leaving her yearning for genuine love and acceptance. Then, Sutton Douglas bursts into her life, a powertul figure with a commanding presence and a need for total control. But beneath his polished exterior, Sutton harbors a dark secret - a beast lurking within, driven by an insatiable hunger. As Dolly and Sutton's whirlwind romance reaches a fever pitch, the stakes grow higher. Will their all-consuming passion be enough to tame the beast, or will it ultimately prove to be their downfall? I devoured every word of this book, desperate to unravel the mystery of Sutton's secrets and the fate of his relationship with Dolly. Get ready to be seduced by the world of Tycoon.

The Tycoon is the first book in the Douglas brothers series. The book is written in dual POV, which I believe really added to the story by hearing from both of the characters. I was given the opportunity to read this book as an ARC by the author. This is the first book of Summer Riley’s that I have read. I am intrigued to read the storylines of the other brothers.

Sutton Douglas is our dark seri@1 un@1iver who falls hard and fast for the sweet librarian Dolly Dixon. This book took a minute to really start cooking with gasoline, but once it got there it was crazy. The entire book took place in a very short timeline, like less than two weeks (except the epilogue). The one thing I wish that we got more of was the black market storyline. I was getting to the end of the book and was worried we would not get answers to burning questions. Hang on because you will get there by the end! The end of the book was fast paced. It is an easy read and perfect if you are dipping your toe in the dark romance “good girl” deep end.

I hope this is not the last we see of Dolly and Sutton in the Douglas brothers series. I want to see their love develop over a longer period of time. Also, let’s not forget about Mama! I know she runs that family like a boss! I can’t wait to see if the other brothers are just as dark and twisted.

"Fine. I'll buy you a house. How many bedrooms? 5? 6? How many kids are we going to have?" - Sutton.

Swooning! ☺️

I wasn't ready for this. Heart racing, cheeks burning, and it's only the beginning 😍

"That's my good girl," he purrs, and God help me, I promised I'd be just that. I'd be a good girl for you, Sir 🙈

And Dolly... she discovers parts of herself she didn't know existed and proves that sometimes the right man doesn't just change your life. He awakens the woman you were always meant to be, and it's beautiful 🩷

Secrets, family, and all the heat, this book has it all 🔥

A 4.5☆ read. When he murmurs, 'Good girl,' it isn't praise. It's a command, a promise, and a threat rolled into one. The kind that makes your knees weak and your body obey before your mind catches up. Sutton! 🥵

⚠️ Check the trigger warnings. Your mental health matters 🌼

This book felt dark, and impossible to put down. Dolly Dixon came across as sweet, and relatable, while Sutton Douglas carried that dangerous charm that made every scene with him magnetic. Their chemistry exploded on the very first page. I really liked how Sutton’s obsession to protect Dolly clashed with his darker side, and how Dolly stayed soft but never weak, finding her own strength in the middle of all the chaos. The Douglas family added even more drama, and an energy that made me want to know more about them. The writing was sharp but emotional, with a pace that kept me turning the pages fast. In the end, it left me hooked and already craving the next chapter of this world. Thank you so much to the author for giving me the opportunity to read the book in advance, I received this for free and I'm leaving an honest review.

This was a spicy slightly mysterious book. Until about chapter 10, Sutton kind of gave me the ick. I just felt like the type of relationship he had with Dolly was a little rushed and it was a little inconsistent, she almost exclusively called him Sir but then would address him by name randomly. Dolly’s ex roommate was the actual worst though. It was pretty cute how quickly Dolly and Sutton fell for each other because Sutton was very much not the relationship type. Uncovering the truth about him and his shady family was awesome and I genuinely didn’t know how it was going to end until part way through the epilogue. Dolly meeting Sutton’s mama and completely charming her was great. The spice in this was really delicious and I’m excited to read about the other Douglas brothers next.

The story has enough twists and turns to keep me hooked. This was a dark, seductive romance that grabs you by the throat and refuses to let go. Sutton Douglas is the kind of man that is unhinged and protective that you shouldn’t want to but can’t stop obsessing over, and the dark side his family is something your brain says run but of course you don’t. Dolly is a down to earth, relatable FMC that is hard not to feel connected to her, she’s middle class, religious family and just looking for someone to love and be with. The chemistry between these two were Off the charts. the plot was dark with a twist, it’s funny in unexpected places, that kept me hooked to the very end. I truly loved this story and can’t wait to read more about the other Douglas brothers.

Explosive Chemistry + Dark Romance = Addicted!

This was my first read by Summer Riley, and wow—what a ride!

Sutton is the definition of a morally grey alpha: dominant, rich, dangerous, and completely manipulative… in the best kind of dark romance way.

Dolly is such a sweetheart—gentle and kind, but with a quiet strength that really shines. She may be submissive, but she’s no doormat. She gives Sutton a run for his money, and their dynamic is everything.

The chemistry between them is off the charts from page one—intense, raw, and magnetic. If you’re into dark romance with a bit of an edge, this book will absolutely deliver.

Definitely recommend for fans of possessive heroes, strong-but-submissive heroines, and steamy power plays. I’ll be picking up more from Summer Riley for sure!

I'm normally not a huge fan of dom/sub, but this one didn't give me the ick. Sutton was definitely morally grey, but in a sweet way! Dolly bugged me the first couple chapters, but then she grew on me. I love that she had a backbone. This was my first read by the author, but won't be my last. I hope we get to meet more of the Douglas clan.🖤

I just love Summer Riley, I met her on Insta and she is just an amazing person..So when I was asked to ARC read her first book written in 1st person pov, I said "HECK YEAH!" I loved Sutton and Dolly!! Dolly is a sweetheart, normal, everyday girl with a heart of gold but also a backbone. Sutton was born into the riches of his families "business", is a morally grey man with a taste for dominance and blood while also still a Mama's boy. Sutton’s devotion to Dolly shined throughout, and the spicy scenes were definitely delicious! This one kept me flipping page after page! There was intensity, bloodshed, steamy heat, SHE'S MINE, and a lovely HEA. If you're looking for a dark romance read that you can eat up in a day or so, check out The Tycoon!

I received an advance review copy for free, and I am leaving this review voluntarily

Review in exchange for ARC**

OH MY LANTA. Summer Riley has crafted the perfect spicy book boyfriend in Sutton Douglas. A MMC who is absolutely swoon worthy. This book was fantastic and a wild ride from beginning to end. With a nice fast pace and plenty of spice this book was impossible to put down. Every time I thought I knew what would happen in the next chapter I was proven wrong and my jaw was on the floor. We can hope to be so lucky as to have more installments of the Douglas Brothers in the future.

Summer Riley delivers big with her first 1st POV novel! I was lucky to read an ARC and loved every moment. Dolly Dixon is relatable and grounded, while Sutton Douglas is her complete opposite wealthy, morally gray, and used to flings. But Dolly flips his world upside down, and he falls hard from their first date. This story is a nonstop rollercoaster of tension, emotion, and scorching chemistry. The spicy scenes are next level! Prepare to laugh, swoon, and feel the undeniable love between Sutton and Dolly

Book one in The Douglas Brothers series. Dolly is a simple girl with dreams like us. Family, marriage and a love that books write about. Sutton is dark rich with a darker family trade. Lies and secrets come to lite. Sutton has to choose between duty or love. Dolly has to choose between accepting his legacy or walk away. Love d it he’s amazing. So dark yet amazingly sweet when it comes to her.

ARC Review of ‘The Tycoon’

First off, I thought it was going to be another ‘billionaire falls in love with innocent girl’ romance.
I was wrong, it was more than that.
It had some thriller aspects in it. Especially when finding out what he does for living. That made go oehhhh yes! Now we are talking.
But, it didn’t go deeper into that side of the storyline, which eventually made me give this rating. Would have loved to see more of that world he is in.
Sutton was fine as a dark crimson wine, enjoyable, but if you drink too much, boy you’re in trouble lol.
Dolly, guess she is everything a wannabe innocent girl would be. Her character was nice.
The mom? I dislike figures like that, because they really do exist.
Sam? I super liked the graphics that happened to him🫣🤣
Their 🌶️ is a delicious buildup where Sutton really takes his time and the lead in bringing everything out in Dolly.

This is a gorgeous billionaire plot with a dark twist, dominating MMC, innocent big eyed sweet FMC with sizzling playful dynamic.
A 4/5⭐️

Sutton instantly turned into a big teddy bear for Dolly, and she got his cold heart beating. But he is hiding a dark part of himself and his family, and needs to come clean before bringing her into the business. But can sweet and innocent Dolly look past the beast that lurks in the shadows?

So I wanted to say I loooooooooved the insta-love between the MCs 🥹 Sutton and Dolly worked so well together although being complete opposites. And how the Douglas family keeps their money and reputation 👀 honestly wasn’t expecting it (but I do tend to go into books blind 🤭). It was a quick and fun read and I can’t wait for the next book!

Thank you for the opportunity to read this as an arc!!

Wow I read it in a day. I loved the dom/sub relationship in this. Sutton and Dolly were an amazing couple. I also absolutely love mama. She is a character that will live rent free in my mind. Mama and Sutton reminder me of Vincent from Elle Thorpe’s Start a war and his mama but Suttons was definitely more loving. I would love to read more of this family. Definitely a dark romance so check the trigger warnings.

What a perfect mix of a beautiful and spicy book!
Sutton is the ultimate sexy billionaire! He's dark and mysterious but turned to mush the minute he met Dolly.
And our sweet Dolly! She's charming and so bubbly and she's down bad for our boy Sutton.
Their romance was fast and so spicy, but its also sweet and passionate. Sutton is a Dom and with Dolly's very limited bedroom experience, she made the perfect sub for him.
This book contains some pretty serious and heavy topics, so I highly recommend checking trigger warnings.

The writing kept me turning pages, and the overall concept was unique and intriguing. That said, I did find myself wanting more depth in certain areas. The characters could have benefited from stronger development and more backstory to make their choices feel grounded. Some plot points felt a little rushed, which left me wishing the pacing allowed for more buildup. The FMC at times came across as childlike and immature, which made it harder to fully connect with her. Also, while there was a sub/dom dynamic, it was never really explored in a meaningful way, which felt like a missed opportunity given how it was teased.

Overall, it’s a captivating read with great potential that just needed more depth and polish in character work and pacing. Still, definitely worth picking up if you enjoy dark, edgy romance with a unique setup.

Summer Riley never disappoints me. This new series is a thrilling journey. I can’t wait for the next Douglas brothers story.

Tycoon has many twists and turns that has me guessing what would happen next. I absolutely love this in a book. Summer threw me a couple times. I really thought I knew how it would end and man I’m so glad I was wrong!

The family dynamic from the very beginning was so fun to read. The first few pages had me hooked and ready to find out what this family really is doing. What do they know about Sutton’s killing? Do they know? Do they help him? Will Dolly make it to the end? Read Tycoon to find out. You will not be disappointed!
