Celtic Lover's Knot

by Annalynn Nicole

I thought being the Boss of the Irish Mafia would be the hardest thing I would have to conquer in this world, but I was wrong...so wrong.

Not long after, I handed my kingdom to my eldest son.

My foundation, which had held my world together all these years, came crumbling down in a way I never expected.

The love of my life was handed news no one wants to receive, especially not at this stage in our lives. 

This can’t be happening to us.

How will we explain this to our kids?

And

Will we still get the forever that we promised each other all those years ago?

ARC Review:

I was mad at the beginning of the book.

Then I was sobbing my eyes out.

HOW DARE YOU!

Stars: 5/5 for emotional damages.

Finally, We get, Peter and Graces story. Grace was in college when she was informed that She would be marrying Peter O'sulivan. Once she found this out, she was going to argue with Peter about the "change of plans" however Peter kindly reminded Grace about the video he had of her with him that he would send to her father. Peter and Grace end up being married for 30 + years when Grace is diagnosed with Stage two ovarian Cancer. After talking over her options Grace decided to start chemotherapy then have surgery. However. Grace did not want to tell their Kids until after her surgery and their 3 grand babies were born. When Grace Finally tells her kids of her diagnosis they are upset she didn't tell them sooner, as they would have been there to help/ support her and their dad. At Graces Cancer remission party Ellie goes missing. What happened to Ellie? Peter and Grace are perfect together. Grace is the calm to Peter’s crazy. I do understand the waiting to tell the kids about her diagnosis, but I keep wondering how differently her recovery would have went with her kids support.

I am obsessed with Annalyn Nicole's books and this one didn't disappoint.

Peter knew that Grace would be his and he did everything to make sure that stayed true. Grace wasn't unhappy but she wasn't the happiest she could be. Peter was keeping her at a distance emotionally until she ends up pregnant for the first time. Soon, Peter doesn't want to keep her away. He gives her everything including his undying love. Their the happiest they've ever been until they get the results about Grace. Peter isn't sure he can survive the news; Grace is his entire world. But with Grace's news, and then something going on with one of his twins, he's not sure of anything right now.

Only thing I didn't like was the cliffhanger because I mean who likes those? I can't wait to see what's coming.

"I finally get to spoil you and pamper you without anything else going on."

This book is classified as Mafia Romance, and is book four of tan interconnected series. It does have a trigger warning list: arranged marriage, bullying, cancer, control, DV, EA, family conflict, hospitalization, illness, medical procedure, organized crime, pain, sloot-shaming, phobia of needles, medical treatments, surgeries, and pew pew violence.

Grace is studying American Art and is put into an arranged marriage with Peter. Kayleigh is their daughter and she is studying to become a nurse.

Warning: this book does end on a cliffhanger.

Celtic Lover's Knot is book four of the O'Sullivan Series.

We get a bit of a snippet into the history of Peter and Grace. While some of the men in this series can be @$$holes, Peter isn't as bad. Yes, he does some things to Grace that are corrupt. However, he doesn't belittle her or cheat on her or do anything really bad. He knows they are going to be together and keeps an eye on her until she can be informed on their future together. We see them struggle with some bad aspects of marriage and see how Peter really works on being a good husband to Grace.

Now the ending really sets us up for the next book in the series which I think might be a bit of a doozy.

What a fantastic Novella. I loved getting to read Peter and Grace's story, we have seen so much of then throughout the other books it was enjoyable to get their back story and how they fell in love with each other. Who knew he basically blackmailed her in the start. Seeing Peter show strength for Grace when she needed it was heartwarming. When she finally comes clean regarding her diagnosis to her family they hold firm in their support. They truly showed up for their mom. Then we are hit with that cliff hanger at the end and now I can't wait to see what the next book entails. I was given this book as an ARC for my honest review.

Annalynn Nicole has done it again! Couldn’t put this book down.

Peter and Grace started out as any arranged marriage but then you see how much Peter changes to make their relationship better. The love they have for each other and how he’s always there for her is so heart warming. They still have their hands full with some of their kids but definitely stick together and handle things as the strong couple they are.

This one hit a bit close to home and definitely had me in tears. Absolutely love how Annalynn keeps everything flowing.

For Peter, stepping down as a leader was easier than dealing with domestic life, where the younger children constantly bring conflicts he does not agree with. He knows that one day they will behave differently, but also understands that this will only happen when they find something — or someone — they truly love and feel the need to prove they are worthy of.
Peter fears his children may not have the same support he once had. And what frightens him most is not knowing how he will guide them… without her.

Loved it!! I can't (okay I can) believe the way she left us hanging with that ending... I can't wait for the next one!! Getting to see these other stories has been so fun and some have be frustrating with the way they start their relationships... this one was no different I wasn't happy with MMC at the beginning and it got better and to where we all know them and love them but doesn't mean we like them all the time.. :)

Another good book! This series is definitely interconnected and you truly need every POV to get the ever growing picture.

That being said even though it’s a big series, you can read the book as a stand alone. You’d just be missing Tis bits here and there but nothing major.

LONG LIST OF TRIGGERS. DO NOT READ IF SOMETHING ON THE LIST IS ONE OF YOURS!!

I love learning more about everyone that gets mentioned in the series! Cant wait to read more

I was not prepared for Peter’s and Grace’s story. This story pulled at the heart. I learned so much about them and their marriage. We have seen this couple in the books about the DeLuca’s but I never got the backstory. This book answered those questions. This is a can’t miss if you have read the rest of the series.

I loved finally reading about Peter & Grace's story! This was a very quick read, but I loved it. They've been through so much together & I loved seeing their relationship grow into what it is. This is a love story for the ages. Although it started off rocky. Highly recommend this novella & author!

[Jessica M Rogers · Rating 5 out of 5]

You know I won’t lie I was so mad at the beginning of this book. But by the end of it I was sobbing like a new born baby. I was joked once again from start to finish and I can’t wait to read more from you girl m.

The story of Peter & Grace that, just like with Nonno & Nonna from the De Lucas, gives the needed pieces to a power dynamic I wish was desired in every relationship. Cant wait for their next journey.

[Selina Nagy · Rating 5 out of 5]

This is Grace and Peters story! The way was Peter loves and cares for Grace is something we all wish for. I can't wait to read the next book to see what happens.

Loved it, great characters storyline and plot, Action packed, dark, intense, gritty and so delicious. It's a rollercoaster ride, with twists and turns.

[Jonnica · Rating 5 out of 5]

Such a cute short novella telling us about Peter and Grace's story. You here about these two alot in the other books but getting the back ground story of how these two fell in love was really good. They finally get there happily ever after but then tragedy sticks! Will things turn out good or will it end in a sad way?

[Lori · Rating 5 out of 5]

Peter and Grace… heart wrenching beginning but oh so much devotion in the end. Super short story - loved it! Looking forward to seeing more of them in future books!
