This Love is Undeniable

Rate this book
Life under a microscope is stifling for anyone, but for Grace Easton, the world’s most recognizable pop superstar who has both feet firmly cemented in the closet, it’s particularly hellish. After walking away from the love of her life five years ago because she wasn’t ready to come out, she’s become a master of smiling for the cameras that hound her every step to hide the fact that she’s miserable.

Most days, Veronica Adams would say that she’s happy. Her work as an actress is fulfilling, and while it’s not easy to heal a broken heart when the woman responsible for it is a global superstar, with every year that passes, the ache in her chest gets a little easier to manage. She’s not over it, but she’s past it.

Or so she thinks.

Theirs was a love story that once played out in secret before being crushed under the weight of the world’s attention. When they’re thrown together in an impromptu chemistry read and then by an unexpected offer, they’re forced to confront the past. Their broken hearts are proof that love isn’t always enough, but maybe, just maybe, this time will be different.

I've read quite a few lesbian celebrity romances. This certainly wasn't one of the most exciting. It was all so detailed and therefore a bit boring. At times, it felt like a behind-the-scenes documentary.

There was barely any storyline. I kept waiting for something noteworthy to happen. That moment never really arrived.
I don't know if it was just me, but I just couldn't quite stay focused.

While I can certainly appreciate an extended sex scene, this book had a lot of them, but they dragged on for ages, and it was pretty much the same old every time.

There were some really good parts, but even those were sometimes dragged on too long.

Such a good story

MJ Duncan is one of my favorite authors. She tells the whole story of how the two MCs where together but had split up. They are put together by chance and the chemistry is still there. They work through their differences hoping for a second chance together. Yes, there are plenty of love scenes that are written beautifully, but is that not what we do when we get together. This is a wonderful and beautiful written second chance love story that everyone needs to read.

Not my favorite of MJ's!

Although I've loved so many of MJ's previous books, I'm sorry to say this one just didn't do it for me. Maybe I'm just too old for this much sex! The beginning and end were terrific, the telling of the movie making was very interesting, and the passionate intensity between mega pop star Grace and Irish actress Veronica was deeply felt, but there was so much repetition even down to "the hands between her shoulder blades." If three or four chapters had been cut from the middle, the book would have flowed better. I prefer a journey of the romance, not just the physical aspects. However, this will not prevent me from reading another of MJ's books. She is a terrific writer!

Good start. There aren’t misunderstandings at the beginning and I am settled in to see how the mains cope with probably the same challenges that broke them up before, this time round.
I enjoyed the fact that most of the memories of the relationship, at least initially, were good. Also that the “I don’t know if I can trust you again" seems real and reactions are consistent with that.
40% in and I am not sure where the story is going. Yes there is a certain amount of tension to see if the main that ran away last time, will run away again, but if they don’t, I’m not sure what will fill the book other than descriptions of how wonderful life is now, which since we didn’t live through at the time the awful experience of the split, doesn’t have the same pay off!
So many intimate scenes means the writer is using a lot of different words to describe basically the same thing over and over with the result some of the word choices are possibly only made because they hadn’t been used yet, not because they are the right choice aesthetically for that type of scene.
I am forcing myself to read on because there is no tension and I am just reading about them being happy. To alleviate the feeling, I took a break for a few books, and it worked because going back to reading about them being happy was nice. However I kept thinking there would be drama or angst. There wasn’t. If you are looking for a happy escape with loads of intimate scenes and minimal, bordering on no drama, them this will be perfect for you! If you are looking for more, this will not be the right answer.

This book had potential, the popstar Grace is back from a tour and is asked to write the music for a movie. A movie where the lead is her is her old girlfriend Veronica that she broke up with five years ago because she was not ready to come out. When visiting the set Grace is asked to play Veronica’s love interest in the movie and she accepts. This could have led to some awkward moments, some resentment over their past but no. Veronica forgives Grace at once and then the rest of the book is just about hooking up on and off the set and the sex is not even hot, it is just never ending, repetitive and boring. I am sorry to say that one of the most boring books I have ever read, and I will never understand how so little storyline can be dragged out on 480 pages. I regret I did not choose to DNF.

Slow Burn & Engaging

So this is different in a good way. There’s no Third Act break up … that all happened years before page one.

What tou get is two women learning to forgive and reforge their connection so they can rebuild a relationship that will endure. One MC must find the strength and courage to come out and the other has to learn to trust her again.

It’s obviously well researched, and is leaps ahead of the typical celebrity romance trope. The attention to detail from this writer is evident and appreciated. Many indie writers who do the celebrity romance trope, especially, do little to no research (as evidenced in a glaring lack of details) and the details in this one truly enriches this story and helps with reader engagement.

I would have liked to see more non-sexual development between the MCs, maybe some on-page emotional development. I really liked the style of the story and that there was no present day breakup, but it felt like there was just a little something lacking.

Despite this, it is still a great read … it just felt like it fell a bit shy of being fabulous. Like it was well written, but not as superbly crafted as it could have been. I would still recommend this book for those new to this author, and especially for those who have read her other works.

For more selective readers, this falls a little short of the bar set by, say, Midnight Rain, for instance. But again, it is still a GREAT READ, one I recommend without hesitation.

Mega pop star Grace Easton and actress Veronica Adams had a romance that ended badly, but time moves on. Grace is called in to do songs for a new film, and V is there, the lead actress. However, finding a costar is becoming a issue.

Veronica is stunned to see Grace there, but hides it. This is also a lesbian film, and as Grace refused to out herself, she figures that will be that and she'll leave.

The director and producer suggest Grace and Veronica read a scene so Grace can get a feel for it... and the chemistry is so good they ask Grace if she'll costar in the film!

(We find out that photographers chasing them triggered a car crash that hurt V. I'm getting Grace's issues on this more, now.)

I did kind of go huh as Grace owns her record company. Why be worried to come out? I guess the fans could turn on her but still...

The supporting cast are also very solid. The actors and each heroines' best friends are really entertaining.

3.5 stars, rounded up to 4. My only gripe is it lacks conflict, really...

I like a Hollywood romance and there were definitely things to like in this. A decent length book (as usual by this author) and a nice second chance romance. The intensity of feelings between the two MC’s is well conveyed. I also liked the way that Grace didn’t mess about on the coming out issue - once she’s got Veronica back, she’s all in!
Less great was the lack of much drama and action in the plot, the number of times the MC’s said ‘I love you’ to each other (too many to count, but a LOT!) the overuse of an Irish term of endearment apparently meaning ‘sweetheart’ and an excessive amount of kissing, love biting (who likes being marked all over the place with hickeys?) and a surfeit of sex.
Certain aspects of this reminded me of the wonderful ’And Playing the Role of Herself’ by KE Lane, but that is far superior IMHO.
N.B There’s a typo in the first paragraph of Chapter 6 where MC Veronica Adams is misnamed as Victoria. That threw me out for a moment as the famous Victoria Adams is of course ‘Posh Spice’…and now Lady Beckham!

Cute

The story is cute. I didn’t enjoy it as much as some of MJ Duncan’s other stories though. More of a me issue than a story issue. I didn’t really connect with either character.

Grace’s entire issue seems to be that she just couldn’t take a stand and that seemed weird. Also, all the wishy washiness of ‘we can’t come out because people will make a big deal of it’ was… ehh?

Like, alright, the biggest music star in the world. She’s worth millions. Who cares if some of her fans get upset because she’s not the hateful Christian they want her to be? Just come out and let the bigots get over it on their own damn timelines.

Also, I loathe the term ‘break the internet’. Don’t use it. Just because your crappy little website was slapped together by your teenagers friends and it can’t handle a few hundred thousand visitors, it didn’t break the internet.

It’s a nonsense term, and shows how little you understand about it.

A feckin great book. This is how a wlw ROMANCE book should be, lots of love scenes and other beautiful moments. Nobody's grandma, grandpa, mother or father had to die in this story. Nothing but pure happiness after Veronica and Grace ... I don't want to spoil what happens. I will just say brace for plenty of romance and love scenes. Read this book if you are tired of someone dying in a lesbian romance, read this book if you want more loving in a lesbian book. I don't know how some people gave it a bad review by saying too repetitive. How in the hell can kissing and lovemaking be too much in a LESBIAN book? Geez, put some happiness in your life and read a good lesbian story where the main characters meet up again and nobody dies, nobody goes for a man and it's nothing but lesbian nirvana in the book.

OMG!

So, I’m a huge fan of Duncan’s books. I love that they all kinda link together through the Easter Eggs included in each book. If for whatever reason you haven’t noticed them I’d highly recommend reading the back catalog.

This book is seriously great, definitely had me hooked from the first few pages.
Loved the characters, the setting and timing. I’ve seen a few reviews saying it has too much spice? I’m gonna disagree with those people. These two had 5 years to catch up on… 😏
I’ll admit to wanting at least one more chapter. Possibly more, but that’s an issue I have with most books I read. I would love to know how the film was received etc.

I’ll also admit I pictured V as Katie McGrath the entire time. As for G, well, yeah, you guessed it, Melissa B. I guess I basically read this as a supercorp fanfic. Am I ashamed of myself…nope 😏

Always great

This author knows how to write lesbian romance books and there is never a bad book from this author. Really good on world building, entertainment and heat. Yes the author is also good with the love screens. However I struggled to finish this book. Not because its a bad book, but simply a matter of preference.

I prefer characters not so much in love right at the start of the book. The "in between" ; that moment from 'just beginning to fall in love' to 'can't live without you ' is lost. And I really love being "part of" that journey. So a great book...but lost the best of what does it for me.

MJ Duncan is one of my favorite authors and after thinking to myself “hmm this is about the time of year MJ Duncan releases a new book” I was so happy to look on Goodreads and see This Love is Undeniable!

MJ Duncan writes beautiful characters and you can feel their emotions. This one had my teary eyed in the first 2 chapters, laughing as the characters fell in love, and crying happy tears by the end. Grace and Veronica had insane chemistry throughout the book and this story made me blush, kick my feet, and performing a dramatic retelling to my wife.

I know I can always rely on MJ Duncan for an incredible story and am so thankful this one came out while I was in a reading slump.

A Second Chance To Do Love Right!

I gave this five stars respecting the way MJ created a story for Veronica & Grace. The history way back when, gave us a connection that was so special in Grace’s quest for a second chance. There were areas where you laughed, areas where you cried. Mostly the story captured their way back to each other and their relationship. The vocal lines being drawn displaying their love for each other without care or worry. Was it a little long, yes. The writer made sure we got the point. But in the world we live in now, love being expressed in every way over a few chapters is alright with me.

Lots of fluff and smut, little substance

I was really excited going into this because the couple is together fairly early on, and I was looking forward to seeing them navigate challenges as a team. It was well written and I genuinely enjoyed probably the first 30-40% of the story. However, I ended up stopping altogether around the 74% mark because the story felt stagnant. The plot ceased to move forward. the book may have worked better at a shorter length, as many scenes and conversations felt repetitive halfway through.

Great to read a story without the 3rd act break up drama etc. Enjoyed it.
Great use of the words susurrus and susurrous
I would have preferred a bit more of the acting and composing / recording written about and got a bit bored of the repetitive messy kissing / eyes rolling back / declarations of I love you in every conversation. I didn’t think ALL the sex scenes were necessary either but I recommend you read and see what you think.

If you’re looking for a love story with very little drama and mostly love, this is the one. This was a love story through and through, and I loved every bit of it. I was on edge in the middle of the book all the way to the end because I thought there was going to be a negative turn in the story like most books. I kept asking myself: “are they going to be happy throughout the rest of this book? This is too good to be true.” 5 plus stars.

Oh, my heart is thudding so hard! so much chemistry lights up this story!

M.J. Duncan certainly knows how to write a very touching (in more ways than one) slow burn love story. My heat index was over whelmed and I feared a burn out! These characters are brilliantly delivered with so much joy one cannot help but laugh out loud! The story is intense and sensitive. I really loved it!

This was a very angst and drama free little rom com. Once the initial second chance stuff was resolved, very early on, it was just a lot of repetitive stuff about the FMCs relationship and a whole bunch of sexy times. What's not to like? But if your looking for good writing with a gripping plot, this is not the one.

The first half of this book is absolutely amazing. The conversations between the two leads were absolutely heart wrenching, beautiful and gripping. I read some of them thrice, just to fully feel the impact of them.

Then after they got together again at the halfway point, it started to drag and become repetitive. They have the same disgustingly sappy conversation over and over again.

Best book I have read in a while.....

I knew this was going to be a great book from the first page; I didn't want to put it down. I loved the story and it was well written. Highly recommended and loved the two MCs. You will not be disappointed.

I loved MJ Duncan’s Symphony Series, but this book was her best so far. She developed Grace and Veronica’s characters with depth and motivation for who they were and how they grew throughout their relationship. The epilogue was the icing on the cake. This is a must read.

Highly recommend reading Halcyon Nights first then this book.

If you are looking for a book that the balance of sexy times to other activities is absolutely dominated by the sexy times this book was written for you.

This is low angst, has some quirky characters, some fun banter .

This was a decent read. However, it's definitely too smooth sailing for me. There was little to no angst throughout the whole book, and even the backstory wasn't fully fleshed out.
Overall, i loved the characters but the repetitiveness killed my enjoyment a bit.

Another excellent book

This book has quickly become another favorite from MJ Duncan. I will undoubtedly read it over and over. While it appears to be a long novel, it reads very easily and leaves you wanting another page to turn.
