The Jennings Family #3

Enemies with an Earl

Rate this book
An earl really shouldn’t sleep with his valet… Or should he?

He’s protective, composed—and hiding a dangerous secret.
Felix Jennings, the Earl of Bentley, has spent his life guarding his family's safety—and his preference for men. Now, he’s stuck with the man of his dreams for an entire week, and it’s threatening to shatter every last shred of his carefully cultivated control. Not even playing the part of unbearable arse can mask his attraction, especially when Felix swears he sees desire in the heated glares Thorne throws his way. But if he’s wrong, it’s his family’s livelihood and his life on the line.

He’s cavalier, sarcastic—and he’s hiding a dark past.
Samuel Thorne, valet and best friend to the Duke of Devonford, despises aristocrats—pompous, self-absorbed scum, the lot of them. And the maddeningly handsome Earl of Bentley is no exception. Sam was forced to valet for him once before and that brief stint was more than enough. Now, his best friend has dropped a he’ll be serving Bentley for an entire week. It’s shaping up to be pure torture—one where Sam isn’t sure if he’ll end up kissing the man or killing him.

It’s a volatile affair, where love and hate blur into one.
And just when they each start seeing with more clarity, Sam’s past comes back to threaten everything.

This story will break you to pieces and mend you back together with a tender and gentle hand. The level of angst and anguish was really unlike anything I’ve ever read. Maybe it’s the subject matter, the hurdles that must be overcome or maybe it’s just the skillful hand writing it. Whatever it was, it is pure genius! I don’t think I have ever been so moved by a story. Enemies to lovers is my favorite trope because I thrive on the angst and the banter, and that delicious burn when things seem utterly impossible. I expected that in this story, what I did not expect was the level of depth and emotion that would be wrung out of it. Just when you think things can’t get any more intense, Lizzie Koz steps it up a notch. While we’re talking about stepping it up, she definitely turned up the heat! These two are HOT, be forewarned. Reading in the hot tub, the water wasn’t the only thing steaming things up, let me tell you. I have loved every single member of the Jennings family and Felix was bound to be good, but he surpassed my every expectation. These two are angsty, full of banter but utterly sweet and devoted at the core. Simply two misunderstood individuals with tremendous heart searching for a place to belong in a cruel world. Once they are able to look past their own judgements, they blissfully find that place in each other’s embrace. Somehow their love seems the most potent of all and I am a better person for having read their story.

*updated from 6/1: As this is not out yet, let me just say WOW!

(I’m giving you nothing else now as I don’t want to risk giving anything away. I will return to fully review when this beauty is out in the world. I had the privilege of alpha reading, so I got really early access.)

If you’ve been around me you know I’m a big fan of the Jennings family- they’re a beautifully loving, slightly dysfunctional (but who isn’t?), hilariously good time and one of my favorite historical romance families. Felix has been the patriarch of the family for a while since his father passed before the series begins, and what a fierce, protective lion this man is. Getting into his head after reading about him for books was beyond rewarding, and everything I had hoped.

Sam and Felix are teased in the prior book, and getting to see their not-so-meet-cute and eventual falling in love was much anticipated. I love their dynamic so much, it’s instant vitriol for each other, and while normally I don’t love insta-hate, it so works here. Felix literally meets Sam on a no-good, bad day, and the two do not make a great first impression on each other. But despite their antagonism, there’s also this underlying attraction burning in them both. And the tension is HOT! But even more so, the banter is so clever and quippy that it’s easy to believe their chemistry goes deeper than just the physical.

These two are both facing some serious trust issues, and I think Lizzie does a really interesting job navigating this. So often I can get frustrated with characters with this problem, but both Sam and Felix have such real and raw reasons for these trust issues. And there are real dangers to them if they give their trust to the wrong person, which has happened to them both in the past. It’s heartbreaking and beautiful to watch them work through building that foundation. Lizzie likes to make her MCs work, but it’s always the most rewarding journey! My heart was absolutely ripped out and then stitched back together in the span of this novel, and I’d let Sam and Felix wreck me again and again.

I like how this series, and this book in general, explores the complicated dynamics between a father and son even when there’s so much love. Freddy was a great father and protector in so many ways, but his pride and duty led to some real trauma for his eldest son. Even with love, things are never simple.

I continue to adore the expanded Koz universe, and am so excited to see what happens next in this world. Every new character we meet is a nugget I can’t wait to dive into later. And I know Lizzie has treats for use we don’t even know to expect….🫰

Thank you to the author for an eARC of this book! All opinions expressed are my own .

2.5⭐️Overall, it's a fluffy Regency MM romance with plenty of smut, but it's not for me. Mainly because it drags on forever—seriously, the pacing is a total slog!

Felix and Sam—both dealing with major trust issues from past trauma—are brought together by a mutual friend when Sam ends up stepping in as Felix's temporary valet. What starts as pure physical attraction turns into a HEA after they help each other work through Felix's trauma and Sam's identity crisis.

Most of the book is completely eventless with zero plot outside of the romance, dragging on for hundreds of pages, only to suddenly devolve into a full-blown soap opera that left me completely dumbfounded.

As for the MCs, I felt completely indifferent toward Felix and actively disliked Sam. The fact that Sam dumps an ungodly amount of sugar in Felix's coffee just to spite him makes him feel like a 22-year-old instead of 42. And how am I supposed to root for a 42-year-old man who has zero life ambitions until a friend of Felix's mocks him as a kept 'stud,' which finally sparks his desire for independence?

I wasn't buying their romance either. They barely had any deep conversations, yet somehow they're dropping lines like this mid-hookup:

“Until you,” Fee said hoarsely. “You are my strength when I have none. You are my solid ground when I’m lost at sea. You’re my clarity when I can no longer make sense of anything.” Felix sank the rest of the way, hips meeting Sam’s arse.


Bro, you guys are literally still hiding your trauma from each other—what strength, what ground?! And seriously, who talks like that while getting railed?

😤 Back on the hunt for decent Regency MM romance.

Lizzie Koz coming in hot (literally) with another installment in the Jennings family series, this time centered on the Earl Felix and his friend Ash the Duke's valet Sam. The two met when Sam was having a terrible day and BOY did they get off on the wrong foot. Since they are both "drawbridge up, walls high" levels of self-protective after some truly terrible betrayals in their pasts, this "enemies" phase lasts quite a while. Oh, and those terrible betrayals? left them both Men Who Cannot Love, so you know what that means! Lots of secrets that only come out (too?) late, and mutual attractions that Felix (literally) runs from.

Once these two start to see real person the other is masking, the story gets emotional and hot. These two are drawn together against their mutual will, and we feel the inevitability of their attraction. Koz has done her research, and we see the ramifications if their relationship ever got out, and the near-impossibility of it working. Despite the odds, she brings home the HEA in an interesting and inventive way, that feels fresh and new. There's a lack of communication and failure to brainstorm the best option that seems like grown men (they are in their 30s and 40s) should do better, and a lot of "wow that person is really upset and emotional, I'll go talk to him...but later" going on. Oh well. I love a book where you think you learn a Big Secret but it was the tip of the secret iceberg, and we get that here.

Koz writes with such humor and fun turns of phrase. At one point Sam's assumptions about Felix are overturned and "Sam blinked. Some crickets chirped in his brain. What now?" She could also teach a masterclass in writing consent in a natural way that really only enhances the heat and emotion of her intimate scenes. "Thorne never failed to ensure they both were fully consenting in this, both on the same page with what was happening and what they wanted to happen." Her books are always a fun read, even when the subject matter is heavy.

If I have a quibble with the book, it's that the initial prank war when they were in dislike mode and having their little fun with each other only served to emphasize the power imbalance. When one of you can make coffee the wrong way so the other spits it out, but then the other can ring the bell pull knowing you have to answer all hours of the night, and (thinks he has based on your alleged role) the power to ruin you, I would argue the person with the power should simply not be doing that. It felt like punching down, even though I know Koz meant it for hijinks (and of course madcap and prank war are my least favorite things, so that might be on me).

While of course all the Jennings Family stories are closely intertwined, there is enough exposition and explanation that this would be an enjoyable read as a standalone, and surely just the thing to inspire a reader to pick up the other books.

Thank you to the author for the arc.

Infinity stars!!!

Felix, the Earl of Bentley, is a man caught between two worlds. He is rigid, composed and fiercely protective of his family, always appearing confident in the eyes of society. Yet, beneath his polished exterior lies a hidden secret: he is attracted to men. This secret weighs heavily on him, for he knows the expectations of his title. He feels trapped, trying to balance his public persona with his true self. The more he tries to keep his feelings in check, the more they resurface when he is around Sam, his temporary valet. Their relationship starts off with tension and dislike, but that tension hides a forbidden attraction. Little did he know, their relationship would become far more complicated than mere animosity.

Sam, on the other hand, had his own struggles. He had a traumatic past filled with heartbreak and betrayal. He despised the aristocracy, including Felix, seeing them as selfish and out of touch with reality. Despite his anger, there was something about Felix that intrigued him, and he could not deny the underlying attraction he felt towards the Earl, which only frustrated him more. Sam viewed Felix as a representation of everything he hated. Still, every interaction with Felix stirs something deep within Sam, creating a confusing blend of anger and attraction. The initial hate felt so real, but it was slowly transforming into something deeper, something they both feared and wanted.

As the plot thickens, Felix and Sam realize they are more alike than different. Both carry hidden wounds and have learned to build walls to protect themselves. Their character arcs are steeped in raw emotion, showing their struggles with loneliness and abandonment. The daring eyes they cast upon each other hints at the powerful love brewing beneath their hostile exterior and the intensity of their interactions shifts from irritation to deeper feelings. They learn that their past pain does not define them but can be shared, understood and even turned into strength. Their relationship teeters on the edge, caught between love and hate, making every encounter feel electric and charged. They challenge each other, pushing buttons while also finding common ground that adds complexity to their relationship. Together, they embrace the beauty of their differences and the heat of their desire, creating a life together filled with hope, laughter and real love.

Lizzie Koz masterfully weaves a narrative that hooks me on every level, breaking barriers by challenging traditional perspectives, creating a more engaging, inclusive, and impactful narrative. She seamlessly combines heat, humor, and inspiration, creating a tapestry of emotions that had me laughing one moment and wiping away tears the next. Their journey evolves from heartbreak to triumph, vulnerable to bold, clashing to harmonizing that gripped me from beginning to end.

The depth she crafts in her characters is unparalleled; they transcend the pages, making me feel their joys and heartaches as if they were my own. The well-earned happy ending for Felix and Sam is not just a conclusion, but a celebration of dreams realized, making the entire reading experience feel like a gift. Their story encapsulates the beautiful chaos of what love really is and that it’s always worth the risk. With every book, Lizzie delivers a rich, meaningful escape that speaks to the soul, leaving me craving for more of her beautiful storytelling. Not only do I highly recommend this story, but I demand that you read it!

This story contains multiple, MULTIPLE scorching hot intimate scenes that will leave you breathless and/or panting. This, dear readers, is a one hand read!

I was honored to read this story in the beginning stages and as an ARC (Thank you!) All thoughts and opinions are my own.

If the Jennings Family has one million fans, I am one of them. If the Jennings Family has one fan, it's me. If the Jennings Family has zero fans, I am dead.

I have been looking forward to Felix's story since I first met him in Compromised for Christmas. In my opinion, there is really not much better than the sorta starchy and definitely overburdened eldest sibling of a family getting absolutely obliterated by mushy feelings. And when that sweet angel's coping mechanism is flying like a bat out of hell away from love? Ugh. Nothing better.

Felix had come to terms with what his future would contain and romantic love just wasn't in the mix.The freedom to explore his identity no longer felt as safe or accessible as it once did and it was his duty to continue the family line. Despite the unconditional love and support of his family, conformity was the only way forward.

Then there's Sam, a man with just as much trauma and only the support of his dearest friend. Sam has every reason to be just as brooding, hardened, and reserved. He believes he has Felix completely figured out, but the more Felix upends these preconceived notions, the more light and playful energy Sam emits.

They are just so well matched that I want to kick my feet and squeal because they offer each other hope and possibility in a world where it really seemed foolish to wish for any at all.

It's a pretty long novel, but doesn't FEEL like a long novel. Every bit of it is not only necessary to Felix and Sam's story, but to the Jennings family canon. I easily could have read another 500 pages. I think this one could probably be read as a standalone...but like don't do that? Read the series from the prequel through Enemies with an Earl. Don't skip an epilogue. Don't skip an author's note. Just trust me on this one...and then immediately come find me so we can yell about the Jennings family together.

I received a copy of this eARC from the author. All opinions are honest and my own.

I don’t even know what I can say to convey how much I loved this book. I had to sit with my feelings about Enemies with an Earl before I could write my review because I loved it so much. I am usually scared away by long books, and this one is long, but not only was I ravenous for it, I found myself slowing down to savor it. I felt Sam and Felix needed every bit of the pages in this book to get to their HEA. Enemies with an Earl is beautifully written, and brought me to tears multiple times. It’s also incredibly steamy. Lizzie C Koz is the real deal. I can’t recommend Enemies with an Earl highly enough. It lives rent-free in my head.

Tropes and such:

Enemies to lovers
Hurt/comfort
Forced proximity
Class difference
3rd person, dual POV
Open door steam

I must be the luckiest girl alive because I got to beta read this, and if you know how much Lizzie loves M/M romance, you’ll be dying to get your hands on a copy. This is an extension of the Jennings family (Book 3); several characters crossover and I would encourage you to begin with Compromised for Christmas (you’ll love it).

Felix, the Earl of Bentley is the heir apparent who harbors the secret of his queer leanings from the world. A modernist family, the Jennings support Felix, but he struggles to live up to the standards he has placed upon himself, as an Earl who must produce an heir. Not only this, but Felix has a tortured past where his queerness was almost brought to light when a man he trusted with his first sexual encounter publicly turned on him before the magistrate. Is it any wonder Felix has major trust issues?

Felix never expects someone like Samuel Thorne to be the man to bring him out of his comfort zone, but Sam has a way of getting under Felix’s skin and niggling at all his insecurities (and fantasies!). Sam is the best friend of the Duke of Devonford masquerading as his valet as a way to keep his sexuality safe and protect his identity. When Felix visits Devonford and is given use of Sam as his personal valet, the animosity and sparks begin to fly. I absolutely loved the power struggle Sam had with being his true self and also restraining himself enough to be considered “the help”. He doesn’t look like your typical valet, all broad and brawny and hulking, and the juxtaposition of him in a submissive role when he’s anything but in the bedroom, creates the perfect amount of tension.

Initially Sam and Felix can’t stand one another—Felix is too “Lordly” and Sam talks back too much for his role, but boy is their attraction electric. If you haven’t read Lizzie before, she is open door, very descriptive, and quite creative with her sexual scenes unlike traditional historical romance. Queer people have always existed and sexual proclivities have always run the full gamut, so to see this featured in a historical is fresh and exciting. Sam and Felix struggle with some very real considerations for men whom could not be partners or marry and they beautifully work through past trauma to achieve their own HEA. I am so excited for historical romance to make room for more characters like these two boys, who just want to be able to live and love openly.

Rating: 🌟🌟🌟🌟🌟
Steam: 🪭🪭🪭
Trigger warnings: homophobia, betrayal and entrapment in regards to sexual encounter and PTSD, mentions of a parent’s death and grief

I’ve been (impatiently) waiting for Felix’s book since the beginning of the series when he was introduced. This book held up to those expectations and then some. Along with all the teasers that’s been placed throughout the series. I loved having all the pieces of the puzzle fitting into place. They were sprinkled throughout and added to the enjoyment of the story.

I loved Sam and Felix and their hard fought HEA. It was raw and messy but also beautiful and full of passion. I cried at a couple different moments and I don’t cry often. It was heartbreaking at times but still plenty of triumph.

Their story takes place over four years and I really liked and appreciated the pacing of the story, allowing time for Sam and Felix to work through their struggles. And while it weaves in and out of the timeline of the other books in this series, it’s very much a story focused on Sam and Felix. It’s a character driven story and the longest of the series yet I was so invested in the characters, it never felt slow.

I’ve fallen in love with the Jennings family over this series and didn’t want this one to end. It’s well written and so you feel the love and care the author’s taken but also the love between characters without it coming off sappy. Some new characters are introduced as well, hinting at what’s to come in a new series. I’m curious to see what’s in store next and I hope it’s not the last we’ll see of Sam and Felix.

This story would be best appreciated by starting at the beginning of the series. But I don’t think you’ll be disappointed you did.

Enemies with an Earl is the third book in The Jennings Family series.

There are eight encounters with lots of heat, passion, and healing.

This is an amazing M/M romance, a slow burn emotionally but (thankfully) not sexually. Felix and Sam are well fleshed out as characters, and the way they learn to relax and lower their walls is really well written. Their relationship happens in a society where they would face imprisonment or death if discovered together, and they must be extremely careful about how they present to the outside world and selective of whom they let into their confidence. Sam, originally of noble birth, almost hanged from the gallows because his family discarded him when he was caught in bed with another nobleman. Felix was betrayed by a lover and narrowly escaped jail thanks to his father's influence. Both men start out with animosity and reluctance to trust, but they are also deeply lonely, hungry for love and companionship. The book covers a long time period (several years) and allows for a gradual development of the characters and their romance. The physical relationship between Sam and Felix is very hot and unfolds in lockstep with their deepening feelings and their individual healing through mutual love and acceptance.

There are cameos by leads from other books and some very interesting new characters, including a Jennings half-sibling (!) who we knew would show up based on the prequel novella. I also appreciated the thought the author put into how an M/M pairing between two noblemen would be presented to the world in a way that would enable the two to spend as much time together as possible without raising suspicion.

Great book overall. A bit on the long side, but worth every page.

Many thanks to the author for providing a free review copy of the book. This is my honest review and I am leaving it voluntarily.

This is a fun, angsty journey for two men from fear and distrust to the love of a lifetime. Felix and Sam start out as valet and Earl, at odds with each other. It's a mask for their true attraction to each other at a time when discovery can mean death. The story also has a lovely and supportive group of family and friends. There is also plenty of heat, good times, and revelry with a very satisfying HEA.

Enemies with an Earl is the third book of the Jennings Family Saga. It follows big brother Felix’s enemies-to-lovers journey with Samuel Thorne, Ash’s valet and best friend. We’ve been privy to some… heated moments between Felix and Sam in Daring with a Duke, and now we finally get to see what sparked their flames of hatred and desire.

Just as Felix carries the weight of responsibility for his family, this book carries a lot of weight of the series. The stories of the other Jennings family members are continued, and we get to see further development between siblings, father figures, and in-laws. I adored seeing Mal’s role in the Jennings family, especially among Lydia’s grown children.

There is also a whole cast of other interesting characters that are introduced teasing new storylines. While the previous books in the series focused specifically on each of the main relationships, this book places the Jennings family in the larger context of society. I’m hoping we will continue to see more of this family in Lizzie’s future books. I’m also not above begging for some bonus content!

Unlike other historical romance series, where readers get to see tiny glimpses of upcoming protagonists, there were enough appearances in previous books and epilogues for me to totally fall in love with Felix and Sam. As someone who usually reads books for the FMC, I can attest that Lizzie writes some of the best MMCs in the genre. They are complex and emotionally-aware (even if they resist their own feelings), but still absolutely panty-dropping.

My heart absolutely crumbled for Felix and Sam. They both have tragic backstories, but cope in different ways. This creates simultaneous attraction, tension, and a fierce chemistry. I couldn’t wait to see them get their HEA, but was also unsure how it would look in a world where public knowledge of their love would have dire consequences. I was not disappointed though. In fact, I was bawling my eyes out.

I’ve said it before, and it still holds true for this book: Lizzie writes spice that’s super hot, like flaming hot (with lots of variety!), but also healing. Every scene serves a purpose, whether is individual character development or a transformation of their relationship. The characters don’t magically fix each other, but they help the other gain perspective that allows them to move forward.

If you haven’t read one of Lizzie C Koz’s books before, you really are missing one of the freshest voices in the genre. If you have, then I know you already plan on picking this one up on July 15th.

Thank you to the author for an ARC of this book. This is my honest review. I’m really this obsessed.

Some stories demand that you stay up late, devouring the love, pain, pleasure, angst, and passion until you finally, finally, get to see the happily ever after. This is one of those books. I didn't want to put this book down. 24 hours. It took less than 24 hours to binge this story (and it would have been less if I hadn't stopped to feed my kid). Unputdownable. A truly brilliant, heartwrenching, tear-jerking masterpiece of falling in love.

Felix Jennings, the Earl of Bentley, is a protector, family man, and exceptional big brother, with a secret love for men that has caused him nothing but heartache. Samuel Thorne, valet and best friend to the Duke of Devonford, has a past he won't discuss and a deep desire to make every aristocrat, aside from his best friend, the Duke, miserable.

When the Earl needs a Valet (Really, he needs to let poor Giles retire already!), the Duke's valet will step in - the Duke has too much to worry about, what with his son such. The loathing Sam feels for stodgy aristocrats like the Earl won't keep him from doing his job. But it won't keep him from pestering the uptight sod, either.

Thank God for the irrepressible Jennings family. Without the antics of a sister, Felix might have simply written off the big man who served the Duke as a poor excuse for a servant - hot, but not a good valet. But the universe has a way of forcing enemies together. They will both simply deal with their loathing. Problem is, Sam can't stand to see anyone being abused by the aristocracy; he won't stand for it. When he mistakenly thinks Felix is being inappropriate with a footman, Sam has to step in. But stepping in, it turns out, might be more like falling off a cliff.

This book is one of the best visceral enemies-to-lovers novels I've had the privilege of reading. There are precious few authors who can make an instant-hate/instant-lust scene work. The believability of the initial hatred or the shift to desire almost always leaves me wanting. Not here. Lizzy C. Koz is, by far, the best character writer working right now. I said what I said. And Felix and Sam are a tour de force of character work. Every action, word, choice, misunderstanding, and connection is so deeply rooted in who these two men are.

Felix and Sam's love story is a brilliant exploration of how repressed sexuality, adolescent trauma, and social strictures can warp self-concept, fracture trust, and still be overcome with honesty, trust, and commitment.

I am so thankful that I received an ARC of this book because I don't think I could have waited any longer for it. And it did not disappoint. If you are not a fan of M/M books please give this one a chance. It continues the story of the Jennings family and if you haven't read the previous books then go right now and get yourself the entire series. You will be so grateful for this advice. The other books in the series were wonderful and I wondered if I could possibly love this any more than the last one. But as I said it does not disappoint. It is the story of Felix, the Earl and Sam his new brother-in-law's valet. It's heart rending, both Sam and Felix have paid heavily for their sexual preference and yet they are compassionate and loving men who want to have a relationship and be together as two people who love each other do. The love scenes are really powerful and they show how special those feelings are between lovers. The story is quite long and I usually get to about 350 pages and think ok, this needs to be resolved. I really didn't get that with this book, I forced myself to go slowly because it was just such a powerful story. Lizzie C. Koz is one of the best new writers out there and this book may change how you feel about love and who should be loving whom. At the end of the day we should all have the chance at happiness with our chosen lover and this book shows us why that is true. This is a book that I will read again and again.

Sam and Felix do NOT like each other. Sam thinks Felix is an arrogant, insufferable hot piece of ass, and Felix thinks Sam is a snarky, disrespectful hunk. In the beginning, neither knows the other is attracted to men, which is impressive given the amount of erections inspired. Once they discover each other (in all ways), their hurdles are far from over, haunted by traumatic events in their pasts, and wary of the threats to their future.

The antagonism between Sam and Felix is filled with so much tension I was worried there was no way the surrender could surpass the build up, but it does. The emotional pay-off is one of the best I've ever read. Where the first half is fast and furious (and sexy), the second half slows down whilst slowing ripping your heart out, stomping on it, then patching it back up (all whilst still being sexy), culminating in a grand gesture that literally moved me to tears. I think it would be easy to say this is a great read for the spice alone, but that would be a disservice to the rest of the book. The character development, emotional depth, and social commentary are all top notch.

Returning to the Jennings family feels like a big hug. This story brims with love and laughter, descriptors that would normally be followed by "sweet" and "cozy", but here instead go hand in hand with powerhouses "yearning" and "angst". Its everything I've come to expect from a Lizzie C Koz, and more.

“Letting you know that for four months you have needled your way so deeply into my brain, I’m afraid I won’t ever be rid of you. I’m afraid I don’t want to ever be rid of you.”


Enemies with an Earl is a really solid mm historical romance, like super duper solid. my one and only negative really is the length, the book was a bit too long and started to meander a bit towards the end. other than that, though? solid. solid. solid.

for example, this is actually a slow-burn. the two leads (Sam and Felix) slowly develop and grow to care for one another over the course of a couple of months/years. the valet/lord dynamic between them is also very well done and i wish more historical romances took advantage of this trope.

another big plus? the side-characters. they all felt extremely fleshed out, and each character was intriguing enough that i want them to get their own book *cough* Rykerkozington *cough* oh and the historical romance vibes were pretty great. Felix was really out here serving Antony Bridgerton energy, and i wasn't mad about it.

“Sam?” Felix whispered, and Sam’s attention snapped back to those burnt-honey eyes. “When I’m with you… I feel like maybe, just maybe, I’m not broken any longer.”


all in all, i highly recommend this one and i'm excited to check out Koz's back catalog!!

Ok loved this. I very much enjoy the world of Koz so I was very ready to like this book. We've met Felix and Sam in previous Jennings books and this one gives you a lot more background on why they act like they do - for Felix especially. In Felicity's book he is an absolute nuisance about her longstanding and increasingly unwelcome betrothal and in this book you get more of a look inside his mind as to why he does what he does - misguided as he may be!

Do not want to spoil, so will not go in to the story too much but one thing is that it is quite long - so you get three (ish) different phases of Sam & Felix's relationship and a nice realistic reminder that finding your life partner does not necessarily mean you miraculously lose all your quirks / tendencies to make and stick to plans you haven't consulted anyone on (FELIX AGAIN!).

It's sweet, funny in places, quite spicy at times and also you get to see pretty much all the Koz-i-verse at one time or another with a one moment where you are likely to be prompted to squeak 'arrrgh send me Ironcrest's story RIGHT NOW!!'.

Have a read!

Enemies with an Earl (The Jennings Family series) is a M/M romance that can be read as a standalone. However, if you read Madcap with a Marquess and remember that delicious scene with Felix (IYKYK) get ready because this book is a scorcher!

Lizzie C Koz masterfully brings you into her world with a refreshing voice. Bringing bold and daring characters that protect and defend those who dare to attack those their families and those they love. It’s a wild, raw, and passionate adventure as we follow Sam and Felix, two loveable men who had their trust broken and over time will discover they are worthy of everything they desire.

✔ Enemies to Lovers
✔ Grumpy x Sunshine “Good Boy”

I have been excited for Felix and Sam’s story since that incendiary peek we had of them in Felicity’s book, and their story Did. Not. Disappoint.

To society, Felix is the powerful and controlled Earl of Bentley and that’s how he wants it. He uses power and prestige as a protective shield around himself and his family, because nothing matters more to him than his family. This also allows him to hide his biggest secret - he’s gay; a secret that could see him imprisoned, exiled, or even hanged, if exposed.

When Felix meets Sam, the snarky valet to the Duke of Devonford with his own secrets, his world is turned upside down by the undeniable attraction between the two of them. Misunderstandings and poor first impressions create hostility between them, but this soon sparks into a fiery passion.

These two freaking broke and melted my heart and I cried frequently. Because of society/the law’s treatment of their sexuality, they’ve both had traumatic incidents in their past that still hold influence over them. Felix buries his pain and trauma under his icy mask, but he’s got such a vulnerable and soft heart and he just loves so damn hard.
Sam’s mask is his humour and flippancy, making light of things and not allowing anyone other than his best friend close enough to his heart to hurt him.

I loved the dynamic between Sam and Felix. The angry hate sex was hot AF, but once those walls start crumbling? Bloody gorgeous. The sheer love and support they give to each other kept making me cry, and I thought their ending was just the sweetest. I love how Lizzie gives them their HEA in a world where they couldn’t openly love each other.

There’s new characters with so much potential and the wider cast of characters was once again delightful. The friendship and support was so lovely. There’s more of the Jennings family and I loved seeing them rally around Felix and support him.

This was an alternately heart-breaking and heart-melting story of two hurt, lonely souls finding love. Lizzie once again writes with a healthy dose of humour and heat that keeps me coming back for more time and time again.

*I received a review copy from the author - this is my honest opinion.

Beautiful Love Story!
This was a perfectly delightful story about two men who are desperate to find their happy ever after and will do anything to achieve that for themselves.
Yes, it is a longish story, but quite frankly, it could not have been written any other way.
It was easy to follow though I will admit that there were a couple of scenes which I personally could have done without, but I was prepared for them and I don't foresee any longlastng effects having read them.
I loved our main characters, Sam and Felix. They were so perfect for each other in every way. I loved the support each of them offered the other and their love was out of this world.
I have just finished reading an early copy of this delightful book and am happy to leave my voluntary review.

M/M enemies to lovers PERFECTION!!!!! 💙💙💙💙💙. This book is so good, I’m making up words…FUCKTASTIC! That’s this book! @lizzieckoz has quickly become a favorite author-she writes with so much passion, wit, heart and humor-I can’t get enough! Felix and Sam are HR couple goals-so imperfectly perfect for each other, so damaged but resilient, so mistrustful yet loyal to a fault. I loved everything about them and their rocky road to their HEA. If ever there was a couple who deserved happily ever after, it’s these two beautiful, broken boys! The book is brimming with sensuality, heat, twists/turns and LOVE! So! Much!! Love!!! It’s a must read for sure. I received an ARC copy but look forward to its release on 7/15 so I can get my hands on the physical copy and add it to my Koz collection!

I enjoyed this a lot. The writing is good, the characters are dynamic, there's plot mixed in the romance that makes it engaging. HOWEVER. In my opinion, this was far longer than it needed to be. I would have been content with the book to conclude at the end of Part 4 and allow me to imagine the way things could work out nicely for Felix and Sam's future. Instead, I read through another 120 pages for somewhat less-than-ideal concluding circumstances. Though I can appreciate the author's effort to work out the complex logistics of how Felix and Sam could be together, the 'reality' of it killed the magic for me a little bit. All this to say, readers can happily end this book after Part 4. Nevertheless, this was a good read overall.

I discovered this writer a few months ago and so far have enjoyed every book I’ve read. My favorite up until now being To my Scot with Love.

And then.. came this book. And it is something else.. It just blew me away. It is a deeply touching story of two H’s that have to overcome past trauma to be able to be together. It is not an easy journey but so worth it.

The characters are fully developed. As a reader you really get to know them. Also love is all around in this story.
Love from the two mains for eachhother, love between Sam and his best mate Ash, love between Felix and his family.

Very emotional story, funny bits as well, lovely writing style (I like the modern take) and the spice is excellent.
This is writing at its best. Please Lizzie, do continue like this. I’ll read anything you write.

I received an ARC. This opinion is all my own.

Felix and Sam's story is full of challenges, passion, and a love that warms you right through! MM love story that has you rooting for them both from the very first. For these two their love really is, potentially, a matter of life and death. Koz writes so well and brings such affection to her characters. Her way of blending the historical facts with the more modern 'take' makes her books fun and relatable and her characters are well rounded and believable and the spice is real and sizzles! Have enjoyed all of her books now, and she is definitely on my 'must have' list for any new title. Do yourself a favour and get this book!

I do not understand the rave reviews for this one, it is thanks to them I gave it a shot. Unfortunately I don t have the patience to finish it since I find Sam absolutely ridiculous. The story starts good, interesting characters but when Sam come on everything becomes a circus. I don t for the life of me understand why Sam's attitude as a valet was permitted. I don t care about his childhood trauma, there is no way a valet would be permitted to act as Sam did, rude, condescending, a complete jerk. Sure, he hates aristocracy but he is just a valet so acting like a spoiled, entitled Az without any consequences is bizarre.

3.5 stars. I enjoyed this even if the modern language was sometimes jarring. The beginning has a bunch of pranks and power struggles which I didn't love considering the huge power imbalance between the two characters' positions. It's sort of waved away with "the duke is my best friend so he would never fire me", but that should have caused Felix to have some major questions about Sam's past, but those never materialize. I thought the second half was better although I didn't like any of the scenes with the Harborage group - they were all too juvenile and frat-like for grown men.

much more than most others

Very good! Believable and long enemies phase, well-paced, developed and interesting characters. This is the first of this author’s work I’ve tried, and it actually prompted me to read Felicity and Ash’s story.

I really appreciate that Ms Koz doesn’t rush things. So many books rush through emotion and action instead of letting us sit it in vicariously with the characters, so this was a lovely experience.

I’m looking forward to the next one as well

I am not usually a fan of MM romance stories, but having ready about Felix and Sam in previous books in the series, I wanted to read more into their story and I'm so glad that I did.
Really enjoyed finding out how they finally got to be together, even though there were multiple obstacles in their way.
Looking forward to the next book in the series now.
I would thoroughly recommend reading this book and the other books in the series.

This story was incredible! And if I could give this book a 10 star I definitely would..

My emotions were all over the place with this book.. i just couldn't help but cry for the characters and get angry on their parts but the happily ever after was just beyond beautiful.. I can't give the proper words about this book because it's just not going to do it justice... All I can suggest is read it yourself and find out how beautiful this story is..
