Duke of Eccess: Seven Dukes of Sin, Book 4

Seven Dukes of Sin #4

by Mariah Stone, Shane East (Narrator), Justine Eyre (Narrator)

Octavius Everard, the wealthy Duke of Excess, indulges in London's most decadent offerings to escape the pain that haunts him—especially at Christmas.

The richest food, the best cognac and the most beautiful women make the "happiest" time of the year a little more bearable. The one sin he has sworn to abstain from? Seducing his three wards' governess. But when Miss Temperance Fields applies for the position, with her tight chignon and no-nonsense brown woolen gown, he's never been so fascinated. Little does he know she has a scandalous secret…a false identity.

Lady Agatha Temperance Hale is an heiress on the run! Threatened with forced marriage or the asylum, she is at the mercy of her gold-digging stepmother until she comes of age on Christmas Day. Being a governess gives her a place to hide. And Temperance is soon showing the duke the joys of the season and sharing her love of science with his wards.

But she never imagined the pleasures her gorgeous employer could show her. And when the virgin governess becomes a seductress, the Duke of Excess doesn't stand a chance of resisting…or guarding his heart.

Their passion is electric.
Their love is forbidden.

But when the truth is revealed, can he forgive the woman he has come to adore more than any indulgence?

[Jenn (The Book Refuge) · Rating 4 out of 5]

The Duke of Eccess, Octavius Everard, represents Gluttony in our Seven Dukes of Sin series. We get to finally learn what leads him to live a (seemingly) carefree lifestyle. The childhood trauma and pain that cause him to act out must come to an end though, when he is made guardian to three of his cousins children. They need guidance and a steady presence in their lives.

Lady Agatha Temperance Hale is on the run from a scheming stepmother, who is bent on forcing her into marriage or else having her committed. So she is desperate to remain undercover until she reaches her majority and gains control of her fortune. She gets a job as the governess to the Duke's charges and finds herself in a whole new kind of danger as she is drawn into the hidden sadness and lure of Octavius.

I really wanted to love this more than I did. I felt for Temperance so much, and I know she was in a difficult situation. I truly do understand why she might not trust men after how things had been for her the last few years. However, the way she put the children in danger, over and OVER again, by refusing to see how foolish she was by keeping her secret while still being within reach of her enemies? It was almost unforgivable to me...

Narrated in dual format by Shane East and Justine Eyre. As always, they do a wonderful job with the work they are given.

I feel like I can count this as my first Christmas book ahead of the holiday season. There’s ice skating, Christmas baking, a Christmas ball, and kissing boughs. While it serves more of a backdrop to a heiress hiding in a Duke’s household as a governess to unruly wards - I’m still counting it.

Temperance is unfairly known as the Mad Heiress due to her love for learning and conducting electricity experiments. All she needs though is to make it to Christmas Day to come into her majority and inheritance. An advertisement leads her to finding refuge in Octavius’ household as a governess. I felt for Temperance and understood why she had a hard time trusting others.

Octavius enjoys his hedonistic lifestyle but recently noticed his habits wearing off on heir and ward. Then he’s up for consideration by the Prime Minister for the President of the Board of Trade, if he can rid his house of scandal. Plus with the addition of the new governess, Octavius starts abstaining from pleasure. I really enjoyed how after this started, he also started opening himself up to emotions that led to his joy of watching others experiencing pleasure. As well as, finally confronting trauma from his childhood.

The stakes were high for Temperance and I didn’t want to put this book down. Wanting to see if or how Temperance would succeed. The children get a lot of page time and I found them endearing and essential to the story and character arcs.

I only felt there should’ve been some groveling from the hero.

Overall, it was an enjoyable story and was left intrigued with what is in store next.

Duke of Eccess is the fifth book in the Seven Dukes of Sins series.

There are two open door encounters plus an additional scene in a bonus epilogue available in a newsletter signup. There are also mentions of a room of sin and restraint that are unfortunately unrealized on page.

I received an advance reader copy from the author. All opinions are my own.

This story is all about abundance and excess. An excess of love, loyalty and bravery. Temperance is a woman who stands her ground and is willing to do what she must to gain her independence. This is how she lands on the step of the y of Excess and becomes governess to his wild wards. Through her kindness, her determination and her iron will she wins over all their hearts and converts Excess into a man who uses his excess for the happiness of those around him instead of just indulgence for himself. I have loved each and every one of the Seven Sins and how their lady love’s have taught them to use their namesake for the good of all.

Shane East and Justine Eyre are two names I devour in historical romance. Shane has the gravel and grit to truly dig into the gruff personalities of nobility. While Justin channels the soft decorum of a regency lady with her gentle tones and passionate expression. Their chemistry and skill take you back in time to a period of love and nobility.

Mariah Stone is a new author for me and this is only my 10th book by her. I read her Dukes and Secrets series and couldn't put them down. I don't read book descriptions anymore so I have no idea what I'm reading when I start a book. Makes for a more interesting read, I think. :) I added book 2 in this series to my favorite books read list for Jan, 2025 and book 3 to my favorite books read for Feb, 2025.

I really liked this book. I liked Temperance and Octavius. I liked the storyline. I felt they were a good match. I liked the suspense of it in regards to her family. I hate that women in those days were considered "mad" or "crazy" because they had a freakin' brain. So ridiculous. It just makes me realize men where afraid for women to be smarter than them. :) I don't usually like MC to have "wards" but I did enjoy Temperance and their interactions. Overall a really good read.

[Ashlyn · Rating 5 out of 5]

False identity is either a hit or a huge miss for me. But Mariah Stone knocked this one out of the park (sorry I’ve been watching lots of baseball lately).

This well written historical romance follows Temperance, a heiress who is running from her stepmother after her father passes away, and Octavius, the Duke of Eccess. These two characters had significant growth through the book. And while yes, there was a slight love triangle, I felt that it was handled extremely well and plays into the next book beautifully.

I honestly had a hard time putting this one down because it sucked me into the story and these characters’ lives. I look forward to continuing this series and seeing what Mariah has in store next!

I read and received an eARC of this book which does not affect my review.

Definitely my favourite in the series so far.

I’m very lucky at the moment, because books that I’m reading are turning out to be great entertainment, and Duke of Eccess keeps up with them.

That was a great story of deception, hidden identity and nice romance.

[Danielle's · Rating 5 out of 5]

A count down to Christmas. I’m a huge fan of the deadly sins and was so excited when the next instalment for the Duke of Sins landed on my kindle. I love the way this series weeps you into a historical time.

The heiress is on the run and a countdown to Christmas is end game. She needs to stay in hiding until she comes of age so her can escape her stepmother.

The Duke of Eccess is looking for someone to take care of the children who have ended up in his care. Ms Fields, our secret heiress applies for the job and the Duke gains more than a teacher for the children.

I really enjoyed this book and love the warming atmosphere. The world building really sucks you in and this couple have all the feels.

[Janet · Rating 5 out of 5]

They call her the Mad Heiress & she’s on the run from her threatening step mother – she just needs to hide until her birthday on Christmas Day when she can access her inheritance. Out of places to hide Lady Agatha Temperance Hale lets Octavius Everard, the Duke of Eccess, hire her as governess to his three impossible wards—never telling him she's the woman half of London is hunting with a fifty-pound reward on her head. Octavius lives for excess—the finest wines, the most dangerous pleasures, anything to numb the ghosts that haunt every Christmas season.
The fourth book in the series & whilst it could be read on its own the series is brilliant & the seven Dukes are such interesting characters. I loved Octavius & Temperance both had loads of baggage & I loved how they fell for each other but whilst he eventually began to reveal his past she couldn’t bring herself to do so. There’s also Octavius’ three wards who had seen off lots of governesses but Temperance’s calm demeanour gradually won them over, all three were a joy but James won my heart. A very well written romance which drew me in from the start & I just loved it & the surprise at the end added to the enjoyment

[Meghan · Rating 5 out of 5]

This series gets better and better. Not gonna lie, from the other books, Eccess wasn’t my favorite. I didn’t love him but now I do. What a troubled man (typical) who got his ish together because a woman came into it (also typical). I did want to punch him at one point but he fixed it. He could fight for me any day 😏

But what I think I liked most about this book was its leasing us to Enveigh who has set himself up to be the villain and I’m here for it. I need a good villain in my fictional life right now.

May I have another?!

what a fantastic read. this one was a thrilling twist and turns over and over. just when you thought it was going to happen big it slowed down and it was back and forth with the drama. I loved it.
the characters were amazing. the period time representation were spot on. highly recommend

Each book in the series just gets better and better! I love the heroine's intelligence, strength and resourcefulness and the hero's unrealized depth of character. Their chemistry is electrifying and the children in the story adds to the poignancy of loss. Love it when love triumphs!.

Octavius Everard, the Duke of Eccess, drinks too much, eats too much and enjoys sex with women. All of that needs to change when he acquires his cousin's three children as his wards and wants a position with the government. In desperate need of a governess, Miss Tempest Field arrives at the door as one governess is leaving. With no references, Octavius takes a chance and hires her on the spot.
You can imagine how three children can get into trouble.Tempest is in hiding until her twenty-first birthday. What better way to hide than as a governess in a duke's home. With patience, love and fear of discovery, Tempest changes four lives including her own. With an overlap of characters from the previous books, I would suggest reading the series in order. Very interesting dukes and ladies who become their wives. A little violence and explicit sex.

⭐⭐⭐⭐
🌶️🌶️.5

Duke of Eccess is the 4th book in the Seven Dukes of Sin series and it gives us a deeper look into why this duke lives a hedonist lifestyle. I loved the setup of this romance and I was hooked from the start.

Octavius Everard, the Duke of Eccess has lived a life full of debauchery. He drinks too much and has meaningless sex with his mistress as a way to escape the demons from his childhood. All that changes when he becomes the guardian to his cousin's 3 children. The kids are acting out and chasing away all their governesses, so he is desperate enough to hire Temperance Fields as their new governess even though she has no references.

Temperance has big secret though; she is actually Lady Agatha Temperance Hale the mad heiress on the run from her stepmother. She is in hiding till her 21st birthday, when she will receive her inheritance and can be free.

I really loved the connection and chemistry between Temperence and Octavius, but I was frustrated with how long she kept her secret even though he showed her he was trustworthy and he truly cared about her. That made the story drag on a little in the last half.

I am very intrigued by Duke Enveigh's book because he came off a little over the top with how he reacted in this one. Interested to see if he can redeem himself.

[Vania - My Little Book Reads · Rating 5 out of 5]

I've been waiting for Duke of Eccess for what feels like forever, because I adore this Seven Dukes of Sin series and I knew Octavius' story would rip my heart out and stitch it back better. And wow it delivered. Temperance is simultaneously exactly what Octavius needs and everything that could complicate his world. Her secret identity, her scientific curiosity, her bravery, all of it makes the "mad heiress" label feel like just the tip of the iceberg. And Octavius… I fell for him hard this time. His excesses, his scars, his guilt, and his gradual softening with Temperance and his wards, every moment was powerful.

I was glued to this book from Temperance running from her past through to all of the moments Octavius feels like he might lose her, or worse, lose himself. There are gorgeous scenes, emotional confessions, playful bonding with the children, plus that tension of "can I trust you when so much is at stake." The romance is there, but also layered: it's about healing, forgiveness, and whether two very broken people can build something real together.

Great book.

[Miaowwow · Rating 5 out of 5]

I loved this book it’s a little bit different from the usual governess/nanny trope and all the better for it, The FMC/governess is an heiress in hiding, a bit of a blue stocking and turns from innocent young Miss into a saucy temptress. Quite spicy.

The MMC is a bit of a troubled lost soul, trying his best but after all he’s just a man some what lacking in emotional intelligence though with a good heart.

There are twists and turns and as always Mariah’s characters are extremely well drawn and believable. I really enjoyed the inclusion of the three children as wards of the Duke of Eccess.


This is the fourth in the Seven Dukes of Sin Series. I have thoroughly enjoyed each of the three previous books and am impatiently looking forward to the rest of the series.

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

I can absolutely recommend these books and Mariah Stone has now joined my “Oh yes please!” author list.

Another great period drama showing the struggle women had to be taken seriously and survive

One wonders how many women were forced into asylums for made up reasons all so others could get money it seems like they would go to any length to do so maybe Mrs Bennett in P&P was right to be concerned re her daughters marrying

This tale around the seven Dukes series is great shows how some men encouraged and supported their wives in their ventures

Trust is so hard when you’ve been let down by those closest to you

Lovely romantic and bit steamy story

Very sweet and heartwarming. I love this series.

[Nicole · Rating 5 out of 5]

Mariah Stone never disappoints with her books..

Temperance and Octavius are characters that you instantly just want to jump through the book and give them the love that they both deserve..

Temperance is being betrayed by her own stepmother the one person who should have protected her after her father passed away instead of trying to have her put away.. Octavius's mother left him when he was a child and his own father made him feel worthless..

Octavius and Temperance are two different people despite that one common thing.. However one thing is certain they feel passionate about each other and 3 beautiful children.. and they will do anything for those 3 children..

This story is filled with love, tragedy, humor,heartbreak, angst and holiday season romance..

I can't wait to see what is in store next for this series...

Que hermosa historia de amor, una novela con personajes bellisimos de los que te enamoras, porque esos tres chiquillos me robaron el corazon. Oh claro Octavio también, ese hombre de solo imaginarlo, se me pone la piel de gallina y tenemos a una brillante heroína que superó sus miedos...
Me gusto mucho la historia en sí, esta bien pensada, muchos detalles y muchas descripciones que puedes visualizar.
Ya quiero leer lo que se viene con la hermana.

After being featured heavily in the previous book of the Seven Dukes of Sin series, it is now Octavius’s time to shine. However, the human embodiment of gluttony has had his wings clipped, metaphorically speaking, fairly early on in the story, and we find ourselves essentially becoming acquainted with a new version of him. This version may not be as entertaining as the previous incarnation, but that hardly means he’s less lovable. While his traumatic past brings a dark shadow to a character who’s previously only been used for levity, his struggling relationship with wards Margaret, James and Sophie, as well as his tenuous romance with Temperance, make him both sympathetic and relatable.
In regards to Temperance, your heart can’t help but go out to her- not only has she lost a beloved father, but she was betrayed by the very people who should have had her back from the start (at least in the case of her stepmother), and in the most insidious of ways- by either forcing her into a loveless (and undeniably abusive) marriage, or committing her to a madhouse, from which she would never escape, all to gain control of her money. Temperance’s fascination with electrical experiments may have been her stepmother’s excuse for wanting to have her committed, but it’s fairly obvious that the vile woman would have come up with *any* excuse to declare Temperance incompetent. This story gave me secondhand anxiety, as I worried for Temperance every time she left the safety of the house or had to attend a gathering with other guests (as it turned out, my anxiety was well-placed).
Her first (literal) run-in with Octavius saw her at her lowest- scared, desperate, and alone- and him at this worst- drunk, dismissive and disrespectful. Yet the attraction was there from the beginning, and never really wavered. In fact, in a very risqué move for a woman of that time period, Temperance was the seducer for a good portion of the story (once Octavius awakened her senses to all of the pleasures- food and otherwise- she’d previously denied herself). It isn’t often we see women take charge like that in a romance, which made for a nice change of pace (especially as it meant that someone as prone to excess as Constantine had to suddenly temper his *own* desires in an effort to keep her virtue intact). Their resulting affair was both believable and *very* passionate, and definitely had my stomach doing flips.
As much as I loved this story (I didn’t even touch on the well fleshed-out storyline with the children), there were parts that rankled me. Despite being so desperate for her freedom (to the point where she turned down a proposal from the Duke of Enveigh, who knew her true identity and was willing to hide her away until she came of age to claim her money), Temperance was unwilling to accept *anyone’s* help, even when it was freely offered by several people, to the point where she almost surrendered to the idea of being sent to the madhouse because she couldn’t succeed at obtaining her birth rite on her own. I wanted to shake her by the end because she was just *so* stuck in this way of thinking that she would have essentially been the agent of her *own* demise. (Thankfully, the realization that she was no longer alone struck her just before that could happen.)
Octavius wasn’t safe from my scrutiny, either, however- as was the case of the previous dukes in the series, he was constantly haunted by memories of his horrible father and the mother who abandoned him, and so it was constantly touched upon, along with his fear that he’d never be enough (ironically by being too much) for someone to want to stay with him. There was also an occasional mention of a carriage accident that haunted him, but it was never explained- perhaps it will be in the Duke of Enveigh’s story, along with Octavius’s sister who was frequently mentioned but never by name- until Archibald himself succeeded in finding her, something Octavius was never able to do. Archibald’s motives for doing this are undoubtedly for the wrong reasons, as he clearly seeks vengeance for Octavius breaking the fourth credo and claiming Temperance as his own, but we’ll just have to wait and see how that all pans out. I understand the need to connect the stories, but I do wish this one had more of well-rounded ending, rather than subjecting us to so many loose strings that we’ll have to wait heaven knows how long for.
Yet wait I shall, as Mariah Stone has crafted an intriguing overall concept with wonderful (and frustratingly human) characters that keep me coming back for more.

[Bonnie · Rating 4 out of 5]

Thanks to Booksirens for a copy of this ebook and this is my freely given opinion.

This is book 4 of the series and features the story of Octavius, the duke of Eccess. He revels in pleasure and overindulgence and in the previous books it has lead to him appearing sloppy and unreliable.

This story gives his backstory and redemption, showing the vulnerable, flawed man-boy behind the drunken, gluttonous facade. In this story, we discover much about Octavius and his family history - and it is dramatic and traumatizing leaving him deeply emotionally scarred. Hence his indulgences in food, sex, and booze - to obliterate the memories, and temporarily fill the voids in his life and soul with passing pleasures.

But his life has changed and he has become the guardian and only remaining family of three young, vulnerable orphans. Because of his fears and feelings of inadequacy, he avoids them, leaving their care to a series of governesses, and this leads to a cycle of them acting out in the face of their own losses and unmet needs - routing 6 governesses since their arrival in the Eccess household.

Lady Agatha Temperance Hale lost her own beloved father a couple of years prior, and has been put under the guardianship of her stepmother. But she has been labeled mad for her unnatural love of science and study of electricity, which was formerly encouraged by her loving father. Her mother seeks to control her inheritance and marry off Temperance to her own nephew, but Temperance runs away to avoid this until she gains her majority and can gain control of her own inheritance. She is forced into hiding when her stepmother makes public her supposed madness and the search for her, labeling her the Mad Heiress. Events prevail, including a dramatic meet-cute, leading her to hide under the persona of Miss Temperance Fields, newly hired governess for the wards of Eccess. At least for another few weeks, until her 21st birthday, on Christmas day.

A hidden identity, forced proximity romance with plenty of steam. Much is learned about Eccess and his childhood, leading to his current indulgences, and how they contrast with Temperance's childhood. He is in pursuit of a high profile government position, and seeks her help for the same, in managing the children, as well as aiding him in forgoing some of his former pleasures, and grows to trust her with some of his deepest secrets and fears. In the meantime, Temperance grows to love the children and Octavius, but is afraid to trust anyone with her own secrets, and fear of being exposed. This story also tests the credo of the Dukes, and appears to cause permanent breaks in the bonds of their stalwart brotherhood.

Sweet, steamy, and emotional, with some Christmas sentimentality.

Lady Agatha Temperance Hale is on the run from her stepmother as the woman wants to marry her off to her nephew or put Temperance into an asylum. So she went to her father’s solicitor for help and is in hiding being known as Miss Fletcher. So Temperance acts as Mrs. Barton’s companion while she hides and then a week later, a stranger comes with inquiries. Since Temperance is an Heiress and doesn’t want to marry her stepmother’s cruel Lord Langston, or go to bedlam, she runs again. But, it is night and she is a Lady alone on the streets. It has been 18 months since her beloved papa passed, she just has to turn 21 on Christmas Day, to get her inheritance and no longer be under Lady Auster control. Temperance loves science and electrical liquid and experiments which Lady Auster hates. Temperance is almost run over by horses, when a horse unseats its rider, who happens to be a nobleman. Temperance runs to the almshouse in Whitechapel that is run by Miss Grace Lockhart. But, she knows that other women need it more, so she is looking for a job/ place to hide.

Octavius, The Duke of Eccess, has taken in his cousin’s three children as his wards: Margaret (14), James (12), and Sophie (8). The children are too smart for their own good and the way the governesses that he hired worked with them, ended up with the women quitting and running. (lol, you’ll see). As one of the Seven Dukes of Sin, Octavius meets with the others- Sylvester, Duke of Irevrence; Archibald, Duke of Enveigh; Constantine, The Duke of Pryde; Lucien, The Duke of Luhst; Dorian, The Duke of Rath; & Roderick, the Duke of Fortyne. With the Dukes of Rath, Luhst & Pryde having married already.

Octavius has gone thru so much in his life that caused him to be the way he is, it is all understandable and heart wrenching. I cried. I laughed. I loved this book. In an advertisement she sees that a Duke is in need of a governess. So she goes and finds out that one had just quit and that it is the man she almost gone run over by. (I loved that meeting by the way- soooo entertaining). Margaret, James & Sophie need to learn and have fun and the way Temperance handle them is awesome. How they change in just a few short weeks is amazing. Temperance tells him of her life, in general, mostly not lies, and when the other Dukes comes (with those that have wives & children, coming as well), She realizes that she knows Archibald. She is terrified that he remembers her. I loved how Archibald handles the situation, but this causes problems later with Octavius. A lot of problems. The book was fun, hilarious, sweet, romantic, crazy with mischief and mayhem, steamy, heartbreaking, heartwarming, inspirational, and a bunch of other things. It was an epic emotional roller coaster ride. I can’t wait to see what happens next and it hurt me to see two of the Dukes so at odds with each other.

Eighteen months ago, Lady Agatha Temperance Hale’s father died leaving her a healthy inheritance. Agatha’s father had fostered her interest in science, specifically electricity, which her stepmother, Lady Auster, believed to be unnatural and unladylike. She declared that her stepdaughter was a danger to herself and others and threatened to have Agatha sent to an asylum. In order to maintain her current lifestyle, Lady Auster needed to access Agatha’s inheritance, thus insisting that Agatha marry her nephew Lord Bartholomew Langston, a cruel and despicable man. As Agatha was only a weeks away from turning twenty-one and reaching her majority, which ended Lady Auster’s guardianship, all she had to do was hide until then. Unfortunately, her stepmother found an unethical doctor who drew up papers stating that Agatha was indeed dangerous and needed to be committed, then publicly dubbed her the “Mad Heiress” and offered a reward for her capture. After being discovered while acting as a companion to the wife of a friend, Agatha barely escaped, later applying for a governess position with the Duke of Eccess, using the name Temperance Fields. Octavious Everard, the Duke of Eccess, had been entrusted with his cousin’s three children after they lost their parents in a fire. The three children, Margaret 14, James 12, and Sophie 8, were a handful and had gone through six governesses in one year. Temerpance was a good match for them and things quieted down. At the same time, Octavious was forced to curb is excessive ways as he was being considered for the position of President of the Board of Trade. His bid for that appointment required well behaved children and holding several social gatherings. Archibald, the Duke of Enveigh and one of the “Seven Dukes of Sin” recognized Temperance from her first Season and offered her is assistance…..and that’s when things got really complicated. The fear of being caught provides an undercurrent of angst which is only intensified by several narrow escapes. The children rally around their governess and there are multiple blissfully domestic moments. Of course Octavious and Temperance fall for each other, but Archibald and the truth she denies Octavious make things much more difficult. This story has lots of action, heartbreaking revelations, emotional ah-has, betrayal, vulnerability, steam and one delightful comeuppance. It is intense, creative, and masterfully told. This is an amazing series, with four down and three to go. I loved it!.

I have loved every book of Mariah Stone that I have read and this one has been added to the “loved” list. She always writes with depth and detail that draws me in right from the beginning. The plots are always so interesting and I don’t want to put the book down until I’ve reached the end. This particular series of the Seven Dukes of Sin has been a fantastic collection so far.

The Duke of Eccess, Octavius Everard enjoyed the finer pleasures in life; wonderful wine, the finest food and beautiful women and in generous quantities. He unexpectedly becomes the guardian of three young children when his cousin and his wife die in an accident. Eccess had an awful childhood so feels he doesn’t know how to be a proper guardian to these children who are going through a new governess almost every month. They are running wild in the household and no one can tame them.

Enter Miss Temperence Fields, who is actually Lady Agatha Hale. She is on the run from her stepmother, Lady Auster due to a choice she has been given. She just has to hide from her stepmother and her nephew for the next few weeks and then she will be of legal age and out of her stepmother’s control. Temperence turns up at the duke’s door and under her alias becomes the new governess.

Eccess notices a difference in the children’s behaviour shortly afterwards and has also noticed how attractive Miss Fields is physically and how she instinctively interacts with his wards who have quickly taken to her. She is smart and enjoys challenging the children who enjoy being challenged. Temperance is drawn to Eccess physically. Neither can stop thinking about the other. Both have issues and each could help the other overcome their problems if they can work together. But secrets have a way of coming out and possibly ending Eccess and Temperance’s future together before it starts.

I love the close relationship between all of the Dukes of Sin and the wives of three of them in these books. They are always there for each other like brothers. Although in this book there is a rift between Eccess and one of the other dukes that is not completely healed by the end of this book so I’m really looking forward to reading more about it in future books. The dukes feature strongly in all of these books as side characters. Each book can be read independently but for full clarity and enjoyment, reading the series from the beginning would be beneficial (and they are fantastic to read too).

Another great installment in the series that had me hooked from the start! The very well-written plot is once again highly emotional and brimming with angst, past dramas and traumas, anguish, a touch of suspense and danger, female empowerment and some steamy love scenes. The tropes are

- Opposites attract
- Hidden identity
- Heiress in hiding
- Employer - governess romance
- Redemption arc
- Found family

As in previous books in the series, Octavius is a tortured lead who tries to repress his childhood trauma and feelings of emptiness and loss with his excessive lifestyle. Temperance is a strong heroine who was raised by her late father to live a life of moderation and purpose, but is declared mad because of her interest in electric fluid and her inheritance.
The two are lovable characters who have sizzling chemistry from the start, complement each other perfectly, and have a positive influence on each other.
I particularly enjoyed the scenes with Octavius' three wards and how the five slowly grew together as a family.

Lady Agatha Temperance Hale, known in society as "the Mad Heiress" because of her scientific interest in electric fluid, is on the run from her evil stepmother and her nephew, who want to force her to marry him or send her to an asylum. She only has to hold out for a few weeks until she turns twenty-one and becomes independent, giving her access to her inheritance. So she applies under a false name as a governess to the Duke of Eccess for his three lively wards, who have driven away all her predecessors in no time at all.
Octavius Everard, Duke of Eccess, lives his life in overindulgence to fill the void in his life, believing that too much is better than too little. However, when he applies for the position of President of the Board of Trade, he is forced to moderate his lifestyle and tame the unruly children of his late cousin. This is where "Miss Temperance Fields" comes in handy, as she is able to connect with the children and also seems to recognize his inner demons. She is the opposite of him and was raised to be measured and purposeful.
As they grow closer, Temperance still cannot confide in Octavius, because it is always the people closest to you who can hurt you the most, and Octavius does not want to lose another person...

Overall, a poignant romance with very likable protagonists, great character development, a touch of suspense and spice, that I am happy to recommend!

I received a free ARC of this book. Opinions expressed in this review are completely my own and left voluntarily.

Oh, what a series this is proving to be. I have read all the books so far and can’t believe they just get better. Each one has such emotion, past along with the seven dukes always there for one another. Unfortunately, in this story two of the dukes will test that friendship and each will lose at the end. I was sorry to see that; I hope the next book will show how they end up and if they can remake their friendship. This is the story of Octavius the duke of Eccess. He had a horrible childhood, a very abusive father who caused his mother to flee with his sister, leaving him with the monster. Christmas is the hardest for him. He covers his hurt, sorrow and feeling of never being good enough, with overindulgence in everything he does. Racing, drinking, women all to stop his father's voice in his head, calling him the “piggy”. All due to him being a very large man, standing heads over most. Lady Agatha had a wonderful childhood even thru her mother died when she was young. Her father loved her and let her learn all that she wanted. He did not hold her back like most would be due to her being a girl. They would do experiments on electricity in his lab together. When he remarried, she thought she would finally get a mother, but her stepmother couldn’t stand her being different. Called her mad. When she finds out her stepmother plans to wed her to her evil nephew she runs. She needs to hide till Christmas when she will be granted her fathers, money and estates. She is almost run over by Octavius who is racing his friends at night, he is drunk, and she slaps him before running away. Later she finds he needs a governess and applies not knowing it is for the same man she slapped, a Duke! Oh, my what these two must overcome and learn before its almost too late. With the three children, Margaret, James and Sophie who are his wards now that his cousin and his wife died in a fire. All are super smart and in need of love and attention. He must change his way if he wants to prove his father wrong and get the Board of Trade appointment. Oh, my I could not put this book down. As Octavius and Temperance fall for the other will the secrets and lies and hidden fears be too much or will love win out? Run, grab your copy and get started. It is helpful to read the books in order, but each can be read as a stand along. I received an ARC from the author and wish to thank her. This is my honest, somewhat long review and am freely giving it.

Octavius and Temperance

“Duke of Eccess” is book four in the deliciously sinful series penned by Mariah Stone, Seven Dukes of Sin. In this offering Octavius is the Duke subsisting on gluttony, and not just food. You name it, he indulged in it—food, booze, women, racing, recklessness, pleasures—until the day he nearly ran over Temperance with his horse in the dead of night. Octavius is such a well written character, he drives the book with his overindulgence then his struggles with sobriety and change. This man struggled with Christmastime, the result of a horrible father and a mother who deserted the family with his baby sister. I felt the jolt when Octavius met Temperance. Temperance was a lady and an heiress on the run from her greedy stepmother and a forced marriage or the alternative, Bedlam. I really like the women in this series and Temperance fits right in. She is intelligent and scientifically gifted with a love for experimenting with electricity. Unlike Octavius, Temperance had a great father whom she loved and who supported her scientific study and independent spirit. Temperance uses her upbringing as a guide when she is hired as a governess to Octavius’s three unruly wards. Biding her time until her birthday on Christmas Day, Temperance hides her identity, not knowing who to trust as well as believing she has to do everything on her own. There is high heat and passion between these two opposites. It is like a raw electrical charge pulling these two together, it gets stronger as the story develops. I liked the fact that Temperance went after what she wanted from Octavius. The world these characters live in is extremely well developed. The pacing of the story kept me interested and eager to see what was going to happen next. I enjoyed the scenes with the other sinful duke in the series, especially the married dukes with their scientifically minded wives. The unmarried Duke of Enviegh, Archibald, is a thorn in this story, at times his motives are suspect and questionable. It goes to show that even the best of friends have rough patches. This series is still going strong, I can’t wait for the next duke and the woman who completes him. Definitely recommended for lovers of historical romance, fans of Mariah Stone, and anyone who likes a good story with standout characters.

Mariah Stone’s The Seven Dukes of Sin series just keeps getting better, and the fourth installment, featuring Octavius Everard, the Duke of Excess, might be my favorite yet. Octavius isn’t your typical duke—he’s a man drowning his past sorrows in overindulgence, especially around Christmas, while struggling to manage his three rebellious wards and salvage his reputation.

Enter Lady Agatha Hale, Temperance, an heiress on the run from a manipulative stepmother determined to control her future. Dodging an unwanted marriage and the threat of an asylum, she takes a job as governess to Octavius’s wards, hoping to stay hidden until she can claim her independence on Christmas Day.

From their very first meeting, sparks fly. Octavius is captivated by Temperance’s sharp wit and strength, finding himself opening up in ways he never has before. Temperance, wary from past betrayals, keeps her true identity a secret, even as her feelings for Octavius deepen. But secrets have a way of surfacing, especially when the conniving Duke of Enveigh steps in, threatening everything.

One of the things I adore about this series is the bond between the Dukes of Sin. They’re not just allies—they’re like brothers. Seeing tension brew between Octavius and Enveigh was tough, and I’m anxious to see how it affects their friendship moving forward.

This story has it all—humor, heart, angst, and just the right dash of spice. Octavius is a beautifully flawed character with a tender heart hidden beneath his rakish exterior, and Temperance’s resilience and fierce independence make her the perfect match. Their chemistry is undeniable, and watching them challenge and heal each other is truly satisfying.

Will Octavius forgive Temperance’s deception? Can she embrace love without sacrificing her hard-won independence? I could go on, but honestly—you just need to read it and find out. Trust me, you won’t regret it.

With lingering tensions around the Duke of Enveigh, Stone leaves us hungry for more. While I have mixed feelings about Enveigh, I’m intrigued to see how his story unfolds. If Stone can make me root for Octavius, I’m sure she has more surprises in store. Bring on the next book!.
