After the previous book and seeing more of Nora, I was basically beside myself at the idea of her getting her own story. Sadly, this was a huge let down

I love Nora. She’s smart and inquisitive and unapologetic for what she wants out of life. Con has potential, but I don’t feel like we even scratched the surface...perhaps it’s because there were only a few chapters of his POV. I didn’t see any sort of attachment between the two of them, except for a passing lust.

Plot wise, it was bland. There’s

I received an ARC from Edelweiss in exchange for an honest review.

The Duke Effect is the last book in the Rogue Files series and it can be read as a standalone. Nora Langley grew up learning medicine directly from her physician father. Unfortunately, the law restricts women from attending medical school, but Nora follows in her father's footsteps as her town's local healer and herbalist. She also exchanges letters with military officers who used to correspond with her father and provid
Sheena ☆ Oh, the Sheenanigans!

I am a little surprised by how good this was especially after reading ‘The Virgin and the Rogue’. Nora was a strong heroine that was outspoken, cared little for what others thought of her, and was true to herself while Constantine was always supportive in all of Nora’s endeavors, even the idea of her furthering her education in medicine and becoming a physician despite the views of women and medicine during that era. I thought her and Constantine (brooding hero in all its many sh

Beware the experimental herbalist!

It's that Nora ... again! The Nora Langleywho's happiest concocting various healing substances, setting bones, and generally physicking those around her. The same Nora who in 'While the Duke was Sleeping' had inadvertently given her sister something to alleviate her menses pain that ended up having an aphrodisiac effect. That was an interesting factor in the mix!
Well Nora's still using her healing abilities. This time however she ends up using ducal heir Constan

Real rating: 2.5 stars. I didn't like how the hero still didn't like her by 50-60% into the book and he only liked her after he tried her potion that made her sister aroused and horny in the previous novel. He said it's not because of the potion but there is no really other way why he would like her as the chemistry between these two lacked a lot. ...more

This was fun. Overall just continued to be a fun time like all of Sophie's books. It did feel a bit rushed to me though. The story was quick moving but then the ending was like so fast it was over too soon. I needed a bit more grovel.

Initial cover thoughts:
This cover gives me Johanna Lindsey vibes in all the best ways 😍

Sparks fly when an unconventional young woman with a sharp mind clashes with a rigid heir to a dukedom in The Duke Effect . Sophie Jordan’s seventh Rogue Files novel is entertaining and light on its feet, though ultimately the story suffers a bit from its rushed pace.

I adored Nora and Ms. Jordan makes it easy to do so. She’s intelligent, curious, and wants to be needed. Nora learned from her physician father and she’s a gifted, learned healer who would

I received an ARC from the publisher via NetGalley in exchange for an honest review. All opinions are my own.

I was deeply disappointed by The Duke Effect, and while my expectations weren’t sky high, I did enjoy the prior book, in which this book’s heroine, Nora, played a major role, so to have this book fail so epically for me was a letdown.

Nora for at least the first part of the book, is still fairly intriguing, as I like that she isn’t interested in marriage and has taken over her late father’

Nora's book was so much better than Charlotte's in comparison. I really enjoyed this one, and was happy that the love potion was also included in this story. Whenever there is a love potion, you know automatically it'll be hot and steamy, and it definitely had heat to it. I loved her personality, and her wittiness. To me she is the more interesting of the sisters. She is strong willed and not afraid to stand up for herself. She is not your typical heroine. She is a herbalist who as a little girl ...more

This was not my jam and I was so looking forward to this book. In Sophie Jordan's last novel "The Virgin and Rogue" we were introduced to Nora, who had created a potion for cramps that also made one hot and bothered. Nora had created lust in a bottle in hilarious fashion. I was looking forward to Nora's book.

Our quirky heroine had followed her father's footsteps and had been practicing medicine since his demise. She had even practiced medicine under his name. A long relationship by letters with

Constantine “Con” Sinclair had been serving in the army for years when he got the letter he never expected to receive – his uncle, the Duke of Birchwood is calling him home, all three of Con’s cousins have died and as improbable as it seems, Con is now the duke’s heir. He returns to London and throws himself into learning all there is to know about the dukedom and will do whatever it takes to please the duke and duchess, who took him in and raised him when his parents died, even marry his cousin ...more

Despite being surrounded by her happily wed sisters, Nora Langley prefers botany to ballrooms and would rather spend a lifetime in her laboratory than consider affairs of the heart. An expert herbalist, Nora has been masquerading as her late physician father for years, dispensing invaluable medical advice. She corresponds with people all over the world, including an old army colonel. But when the man shows up on her doorstep, he is nothing like she expected—he is a young, handsome heir

I received an ARC of this book to read through Edelweiss+. All opinions are my own. The Duke Effect by Sophie Jordan is the seventh book in her delightful Rogue Files series. All of the books in this series are fun to read, balancing the perfect amounts of steam, humour and angst.
I would recommend reading books five and six before reading this one as they involve heroines from the same family, and while Sophie Jordan does an excellent job of filling in the background, I feel that you will find

So the benefit of the previous book being... not good, is that my expectations for this were much lowered. That being said, this was very charming and sweet, and much more in line with some of the earlier books in the series that I really really really loved. The love potion/aphrodisiac makes a delightful reappearance here (with consent) in a scene that was bonkers in the best possible way.

The Duke Effect was an easy, but steam filled romance about Nora (and aspiring doctor) and Constantine (a military man with a strong sense of duty). Nora has been secretly corresponding with Con for years under a false identity and has to prove herself and her worth when the truth comes to light. Their romance was hot and fast, but I really wanted more depth between them. The fast seemed to take precedence over the development. I have not read the other books in the series and wonder if that wou ...more

Sophie Jordan has never let me down before and that held true for her latest. A bluestocking heroine and a stuffy, reserved hero will always bring me running. And also, if you read her previous book, I’m sure you’ll be delighted to know that a certain love potion makes another appearance. *eyebrow wiggle*

I will say that the pacing of this book felt a little unbalanced for SJ book. She’s usually spot on all way through but I did find myself nearly 80 percent through this one and wondering how she

Nora Langley prefers science and experiments to love and marriage despite seeing her two elder sisters happily wed. A skilled herbalist and healer in her own right, Nora has also been using her late father’s name as a physician when dispensing medical advice in letters. She has a robust correspondence, extending as far as an old army colonel stationed in India. She expects no harm to come from her writing and that no one will ever know, until the colonel himself appears in her drawing room and t ...more

Unlike her sisters, Miss Nora Langley cares more about medicine than men. She grew up as an apprentice to her physician father, and continued to answer correspondence in his name after he passed away. Constantine Sinclair was an army colonel until unfortunate deaths moved him from ward to Duke's heir. Thinking to help the ailing duchess, Constantine seeks out "Dr. Langley" for medical advice. But both Nora and Constantine are shocked to discover that neither correspondent is an old man. Angered ...more

“The Duke Effect” by Sophie Jordan tells the story of Nora, the aspiring female doctor, and Constantine the colonel turned heir apparent to a dukedom. Constantine is searching for Dr. Langley, with whom he’d been corresponding for some years, to help the duchess with her mysterious illness. When he finds out he’s been corresponding with Nora Langley instead, the good doctor’s daughter, he is outraged. This leads Nora to show up unannounced in London to prove that she knows her stuff. Of course, ...more
I was SO excited going into this book because Sophie Jordan did a wonderful job of writing Nora as a funny and entertaining character in the two previous books of The Rogue Files series. I really thought that this was going to be my favorite installment as Nora is the main character.

Unfortunately, that was not the case. First of all, I found Nora to be less interesting/dynamic in this book, and Constantine was likable enough as the hero, but I didn’t love him either. Second, I felt that Jordan w

I really enjoyed this book. But I really enjoy all of Sophie Jordan books...

This was a one sit read for me. It was an easy and lovely read. What I love about Jordan's books is that they are really romance centric- which may sound funny when talking about a romance book but these books hyper focus on the relationship and the love between the characters. This book was no different. I loved it. Can I say "I loved it" anymore? Probably!

You can't help but relate to our heroine. All she wanted was to
That stupid fucking aphrodisiac from the last book makes an appearance again. If you did not mind the idea of it this book is fine, I guess. I quite obviously did not like what I saw as the removal of choice, although to give this book a little credit. The hero volunteers to take it. The pacing of the relationship is way out of whack. Heated thoughts/glances for the majority of it, then that weird under-the-influence sexual experience (where It’s made very clear that the hero is not the aggresso ...more

I received an ARC from Edelweiss in exchange for an honest review.

I enjoyed it. The chemistry between both Nora and Constantine Sinclair (love that name) is solid and sweet. I am always a fan of the H figuring things out first -
I liked the realism of the issue with woman "thinking" and practicing medicine. The backlash that Nora felt, it seemed very real, true to that time period and we do go thru some of that even today.
There is a great line about being reasonable. I'm gonna keep that in mind

Sophie Jordan took her adolescent daydreaming one step further and penned her first historical romance in the back of her high school Spanish class. This passion led her to pursue a degree in English and History.

A brief stint in law school taught her that case law was not nearly as interesting as literature - teaching English seemed the natural recourse. After several years
