Gluttony: The Dominant Sinner
In the long-awaited finale to the Seven Deadly Sins series, the Duke of Argyll—London’s most dangerous sinner—faces the one craving that could destroy him.
He is a duke without restraint.
She was never meant to survive his attention.
Feared and desired in equal measure, the Duke of Argyll has built his life on indulgence—gaming, vice, and pleasure taken without restraint. He does not love. He does not soften. And he certainly does not want a wife.
Until one woman alters the course of his carefully controlled world.
She enters his orbit believing herself easily lost, easily replaced.
He draws her close convinced he can remain untouched.
But when danger closes in and desire sharpens into something neither can control, the man who sought a life without feeling discovers the one woman he cannot afford to lose.
A seductive Regency romance of danger, obsession, and a love that was never part of the plan.
For readers who crave dangerous dukes, emotional intensity, and passion without restraint.

This is the seventh book in a series from this author, in which each book illustrates one of the seven deadly sins through its characters.
In this tale, the Duke of Argyll, Gregory Goodheart, is the bad boy that every woman has chased yet still slips through their fingers. He has excessive wealth, seductive charm, good looks and no desire to ever marry.
Miss Daria Kearsley is odd. She is definitely a wallflower, usually clad in black funereal dress, but it doesn't bother her. She is concerned with more ethereal pursuits. Daria has a special ability that has placed her in a rather sticky situation, and the only solution, in her mind, is to make a major change. Daria must convince a complete stranger to marry her, and he is the Duke of Argyll.
There is nothing like a reformed rake now is there? The question is will she reform him. Is that something she even desires or has the time to do?
This story is unique, quirky, has humor and heat. I thoroughly enjoyed it. It makes me want to reread the entire series all over again.

I loved both Gregory & Daria, he’s the consummate rake & she’s a wallflower with a difference. He’s used to women falling over themselves to just be near him, whereas she doesn’t in fact she doesn’t seem interested in him. When he agrees to her proposition he didn’t realise how much his world would be rocked on its axis. I loved it & loved how Gregory was redeemed. It left me with both a smile & a tear

This is the 7th & final book in Christi Caldwell Seven Deadly Sins Series. Although characters from previous books aparear in this story it can be read as a standalone, though the whole series is worth reading.
Gregory Goodheart, Duke of Argyll is a rake who leaves a trail of broken hears behind him. Apart from his younger sisters his only other love is his wicked club Forbidden Pleasures where he spends the majority of his time. More recently he has been pursuing the sister-in-law of his former friend, the Duke of Craven in attempt to get revenge by marrying her.
Unbeknownst to him the young lady has surmised his plan and had enlisted her friend Daria Kearsley to help her. Since watching her father die in front of her when she was younger Daria has been rumored to have foresight, leading her to have an oddness about her, especially when she wears only black. Daria believes she is the one destined to marry Gregory not her friend, leading her to confront him.
As expected he isn’t onboard with this plan, however what follows are some very humorous moments. Gregory comes to the stark realization that his life is very empty & Daria makes him feel alive. Although there are some dark elements to this story as with the whole series there are also some lighter moments. This is a story about redemption & finding love in the unlikeliest of places. Having followed Gregory throughout the series I was hoping he could be redeemed & thankfully he was. I thoroughly enjoyed this story and highly recommend it & all the series.

The quirks make this tale shine
Our hero, Gregory, the Duke of Argyll, is damaged goods thanks to his father and how he was raised. Our heroine, Daria Kearsley, meanwhile is a bit “touched” as she would have been labeled in the time period of this historical romance. She likely is neurodivergent and also has visions.
Author Christi Caldwell has said that the inspiration for Daria is Wednesday Addams as portrayed by Jenna Ortega in the Netflix series. I can certainly see that, which likely is why I adored Daria. Although Daria seems odd to the rest of the ton, she is able to see below the surface and actually understands Gregory better than he himself does.
The time frame for “Gluttony” was short, about a week from Daria’s proposal to our expected HEA. The action moved quickly and Caldwell again put her secondary characters to good use. Daria’s youngest sister is a real delight. I’m hoping she makes a future appearance when she comes of age.
“Gluttony” includes a storyline that has run throughout this Seven Deadly Sins series. A note to readers: the storyline is not finished with this Book 7. Caldwell has promised it will continue in her next series. Still, “Gluttony” is able to wrap up these tales all centered around the Devil’s Den gaming hell.

Another great book by a great author. This is the last book in the Deadly Sin Series, you do not have to read the other books, but I think you should because they are all good. This book is about The Duke – Argyll and Daria. Argyll is a charming duke, who can get any woman he wants and most of the time he does get them. Daria is a unique woman who dresses in black, says what is on her mind, and believes in the curse which is on her family. It throws Argyll because he can’t charm Daria, most of the time she does not even get his sarcasm or teasing. I loved reading the sections with Argyll and Daria’s family, I love how he thinks about something and then does the opposite. The Kearsley ladies are so funny and different, they do not fall for Argyll’s charm either. Reading this book kept me up all night because I did not want it to end, but I wish we had more chapters, because I did not want their story to end, I want to know more about these two who were perfect for each other.
I received an ARC of this book, and I am leaving my honest opinion.

Gluttony delivers a wonderfully different flavor from the rest of the series; quirky, unexpected, and quietly powerful. Gregory Goodheart, the Duke of Argyll, is every inch the untouchable rake: wealthy, wickedly charming, and determined to remain unclaimed. Enter Miss Daria Kearsley, the odd, ethereal wallflower in black who sees the world differently and needs a husband for reasons she’d rather not explain. Their dynamic is fresh, funny, and full of surprising tenderness.
What truly elevates this story is how beautifully Christi Caldwell redeems Gregory. She peels back his layers with such care that his transformation feels earned, intimate, and deeply satisfying. Daria’s uniqueness isn’t a quirk - it’s the key that unlocks him. She writes with warmth, wit, and a deep understanding of flawed characters who deserve love, and she makes you believe in every step of their journey. The only thing missing for me was an epilogue, because I wasn’t ready to leave them yet.

This is the last book in the series "The Seven Deadly Sins". It can be read as a standalone.
Gregory, The Duke of Argyll, is handsome, ruthless, and has no desire to marry. Daria, is a wallflower who always wears black, has a quirky personality and believes she has the ability to see the future, in which she is married to Gregory.
The chemistry is interesting between the two, with Daria usually not understanding Gregory's teasing or comments.
Her family is also quirky, and don't like Gregory.
There are some steamy scenes, characters from other books in the series make appearances, other great secondary characters and some tension between Gregory and his business associates.
I loved this book! It was a great read, and not as dark as some of the others in the series.
I would love to see a follow up story with Gregory and his former business associates.

I had such a good time reading this book. It took me just over a day to finish it and there were moments that I was just cackling to myself over Daria and her family.
Daria feels very autistic coded to me, she is blunt and honest and does not always understand nuance and jokes when interacting with people. Her initial conversations with our love interest, the Duke of Argyll, are absolutely fantastic and our charismatic, extroverted duke, doesn’t quite know what to make of our slightly introverted heroine. He has had quite a difficult life and the opening scene shows how messed up his family was and how much it damaged how he sees love and relationships. This book is less about outside forces and more about him learning to let people in, whether it’s his wife, or her enigmatic family (her youngest sister steals the show! I adore her). I can’t wait for the rest of her sisters to find love.

Least Favorite of the series
I know Christi posted in her readers group that she rewrote the story because she didn’t feel the original heroine Emmy was the one for Argyll, but I don’t think Daria was the right one either. The paranormal aspect of her character was unnecessary. Her personality is too dark and depressing for a romantic novel. Frankly I think the heroine is unlikable in my opinion. I fought to finish the book and was glad I read it on KU and didn’t buy a copy. I have read all Christi’s books and this one is definitely my least favorite of them all. It won’t stop me from continuing to read her new books and I hope the coming books alluding to the continuing war with Diggory go back to being as good as the first 6 from The 7 Deadly Sins series were. I wish I could give it more than 2 stars as I had high hopes for the finale to the series but this one just didn’t hit any marks for me.

Daria has just become my absolute favorite character from Christi Caldwell. This story completely swept me away and has ruined me—in the best possible way—for all other romances. The dynamic between the two opposing characters is nothing short of magnificent. Their chemistry leaps off the page with every interaction, making it impossible to put the book down.
The dialogue is spectacular—sharp, witty, and heartfelt—perfectly capturing the tension, longing, and eventual connection between the leads. The plot unfolds like magic, drawing you deeper into the world with every chapter, and the journey of these characters coming together builds to an extraordinary and unforgettable ending.
Christi Caldwell has truly outdone herself with this one. A must-read for anyone who loves beautifully written, emotionally charged romance!

I am so sad after reading this book. I loved Argyll this entire series. Yes, he is a rake and yes he is sometimes harsh but I like male characters that way. They can be redeemed. I do not think he was done justice in this book. He deserved a better story. I, unfortunately, did not like Daria at all. It was not her oddities, it was that she was dull as dirt. This story was over less than a week and it went nowhere. I can see where others will love this story. The timid woman redeems the big bad rake. I just did not think it worked. I will concede that the end of the story was lovely. I dislike rating books low, I have loved everything Christi has written and was so excited for this story, but it fell way short for me.

Best of the Sinners...
Emmy would not do for Argyll. He needed a power beyond what is normal for redemption, and while the paranormal aspect was a little cheesy, the Duke's reaction to Daria was at times funny and kind, something missing in the other Sin books. Another love hate, families fueding, blackmail, compromise blah blah romance would have been boring. Daria and her family were different and Argyll's reaction to them showed he had potential to be a good man. I'm glad he didn't
come across as a pimp and the F word and sex was used sparingly because it left more time for romance. Emmy will get her turn. Perhaps that young Earl or the drunk vicar.

If I am to be honest, I wasn't so sure about this book the first few chapters. I am a big fan of Christi's work and I know how much heart she puts into her books so I kept an opened mind. I was not disappointed. One of my favorite tropes is arranged or forced marriage. Christi did an amazing job with Argyll and Daria's story. There was the angst and confusion, but done in a perfect amount of time. Not overly drawn out to ridiculousness. Once the book got going, I could not put it down.
I have loved the series and the appearance of previous characters. I truly hate for this series to end, but look forward to future work by the talented Christi Caldwell.

This book took such an unexpected turn. I thought, based on the other books in the series, this would be dark and full of intrigue. However, it was a story of two people coming to know the best version of themselves and falling in love with each other. I loved the representation of neurodiversity; the character of Daria was carefully written and filled with compassion. Also, seeing another side of Argyll also gave another complexity not only to this story, but to his character. This character-driven book was an unexpected and moving love story. I highly recommend this Book.
Review of advance copy received from Author
The conclusion of the seven deadly sins does not disappoint. This series has been the best yet of Christi’s books.
Argyll is a shallow twisted character with no redeeming values - or is he?
When fate says you must marry a thoroughly reprehensible rogue does Daria have to accept it or can she find her happy ever after?
I’m only sorry that this is the end of this series. It’s been an enjoyable journey through the London underworld.

Finally, the delicious Duke of Argyll gets his story! Miss Daria Kearsley is unique, even amongst her unusual family, but endearing in her directness. It was satisfying to read how her forthrightness transformed him. Christi Caldwell is best when she's redeeming rakes and blossoming wallflowers. There is an amusing conversation composed of Shakespeare quotes that was surprising. I wish it had an epilogue. I received an ARC of this book and have reviewed it with my own honest opinion.

I Don’t Want A Wife
Book 7 was about Gregory and Daria. Gregory make her his Dutchess, but he only loved The Pleasure Den. Sex was safe for him but he couldn’t love anyone. Daria’s love by destiny or fate healed and transformed Gregory. So much hurt and sorrow for both of them, but love set them free. I’m sad to see the 7 deadly sins end and have loved them all.

Loved this passionate, tender steamy romance, absolutely loved Gregory and Daria's story of marriage, passion love and a prophecy that should hopefully never come true.

Wonderfully written angst filled, emotional romance. The Duke of Argyll falls hard. I loved the dynamic connection and chemistry between Gregory and Daria, his little raven.
