Six years later, she returns not as a forgotten wife, but as an untouchable prima ballerina. She has a fiercely protected daughter, and a heart Cassian no longer deserves.

But losing her was the one mistake the ruthless CEO couldn't survive. Seeing the little girl with his piercing green eyes shatters his world. Now, the man who took Luna for granted must do the spend the rest of his life on his knees to earn back the woman he broke.

Very good

I really liked this one. The OW manipulated him and when he was drunk, she gave him a hickey twice but nothing happened between them. She wanted him too but both times he was drunk. He didn't want to but he did admit he used her as a sound board and let her cross boundaries. You think? he fired her finally. He was just cold to the h and she put up with it until she heard him drunkenly say some very very vile things about her. It broke her heart so she left. And guess what? You won't believe this plot twist! She was pregnant! Be still my heart! So original right?? Lol I think I've read 20 books in the last two weeks with that plot twist. Then bam, its six years later and she is a Prima Ballerina in London with a little girl. She goes back to Washington for one month engagement and of course runs into hero. He has been celibate for six years because he realized he loved his wife. He never signed the divorce papers either. He wants another chance but its back and forth and back and forth. Meanwhile Cassian is getting close with his sweet little daughter. Only she told him, it wasn't his! That little girl was the best part off the book. She'd was so endearing. She'd pretend he was her real dad him learning to braid her hair was so cute and I loved it. Then he took her to a 'Taylor' concert and he sang along with the songs because he crammed on them the night before. It was so sweet. Of course there is more drama and honestly the heroine started to annoy me. The hero wasn't perfect either. But its definitely worth the read.

Notes for me

Cassian

Luna

Sloane - Cassian’s secretary

Cassian misses their third anniversary so she takes soup to his office after hours.

She finds his secretary Sloane half dressed in his lap. When Cassian turns to her he looks out of it. She leaves heartbroken.

Next night is a gala. Sloane makes it look like Luna threw her drink on her and ripped her dress. Out of the two women Cassian helps Sloane.

Reader knows what’s in Cassian’s mind. He’s believing Sloane was heartbroken in the office about a breakup and thought Cassian was him. Also he helped her first only to stop a scandal. He doesn’t realize Luna fell on the broken glass.

Last straw Cassian promises to make everything up on her birthday. His sister shows a sapphire necklace he’s bought her. At 10 pm Sloane calls saying he’s drunk at a VIP club. She hurries to get him. Hears him say she’s boring in bed, only a business deal etc. she opens the door. Sloane is sitting close to him and wearing the necklace.

Luna leaves for London and Cassian loses his mind.

Six years later she’s a successful ballerina raising his daughter.

Safety

Almost didn’t read because the only review on Amazon said on page cheating.

It sounded to me like no cheating. Sloane just set it up to look that way. However he should have handled her after the office scene. In his mind nothing happened, but the fact that Sloane pulled that nonsense was not ok. He does end up confronting her. Too little too late.

Also what happened with the necklace?

He was absolutely celibate during the 6 years.

"Washington morning traffic was light," has never been said nor written by someone who has actually seen Washington, DC, traffic.

The smex scenes are really gRape-y. She says things like no and stop and he keeps going then her body betrays her and she tells him not to stop. WTH? This is not smexy.

I hate Cassian.

Luna is lactose intolerant. At 72% she is eating ice cream and drinking milk. She's a prima ballerina. Hope she enjoys that painful bloat and gas.

This book desperately needs an editor. The timelines don’t make sense. Sentences drop off. It’s just poorly written. The storyline is all over the place.

The MMC definitely rapes the FMC and not in a dark romance dubious consent way. He’s literally just an asshole. He cheats and forces the FMC to sleep with him as part of his apology. Multiple times.

First time FMC finds him with the OW drunk in his office on their anniversary. He has hickeys from the OW and wakes up tangled in her. He swears nothing beyond the hickeys happened but he also says when he wakes up he doesn’t remember anything. Then he has the audacity to have the OW come help his wife get ready for a special gala. Second time he believes the OW over her and yells and hurts her defending the OW in front of the entire gala. Tells her to find a ride home and stays and parties till 3 a.m.

Let’s talk about the final straw the time he forgets her birthday to take the OW out with friends where the OW wears the FMC’s birthday necklace and he belittles the FMC to an entire group of people. He wakes up, again with hickeys. Eff this guy.

Again there is a surprise kid and the MMC is a good dad so it melts the FMC. Shit partners can still be good dads. No need to get back together and I wish they didn’t.

Not good

This had a lot of issues. First of all, the husband takes advantage of wife physically early on in an illegal way. Women could claim assault. It was not an enjoyable scene. Second, he sent Sloane to style her. He’s a POS and the fact the author wanted to save him was so disappointing. Lastly, it’s written like a teenager wrote it. Not very high-thinking dialogue. Needs lots of work and a new MMC and a non-doormat fmc who literally takes expensive jewelry and says his cheating is fine.

No no no

Spoilers

Did not even want read it past 2 chapters. 1st chapter she catches him cheating but he was drunk and it doesn't count. Happen to be on thier anniversary.
He yells at her, she leaves. Next day he goes home, he grapes hers. Because forcing her to have sex shows she is hers.

She is weak and disgusting, you know he cheated and you stay and you give into the force sex.

Yea, im done dont care. He will always cheat like his dad and she will always stay.

second chance

This story confused me- Cassian is terrible and had no concept of consent. He was selfish and creepy and basically treated Luna like total crap. His secretary was gross and he chose the secretary in many instances. He did change by the end.

Luna left him and was a huge doormat for much of the book. I had a hard time connecting to any of the characters much of the book. You find out back stories and the people grow so it ended well with HEA.

Why on earth would a woman ever take a man like that back? Can you say toxic? Is she desperate? Can’t find a decent man? So she’s going to go back to that fool all because she ended up in his state while in tour? The man is a walking red flag! Run, don’t walk. And don’t look back. What kind of example is she setting for her daughter? Talk about setting the bar low. Poor girl. This story was just straight up awful.
Spousal abuse mentally and emotionally. But yeah, let’s that that loser back.

DNF

You know those short books that advertise apps or those short little movies, again that you get an app to watch, that show up on FB or TikTok? How over the top and cheesy they are? But sometimes they’re so awful that it’s hard to look away or stop reading…this book is like those. The MMC is SO bad that he doesn’t have any personality at all, the FMC finally leaves him after being neglected and harassed by his female assistant and moves to London. She then becomes, after YEARS away from dance and a pregnancy (yes, she’s pregnant when she leaves the MMC), the lead dancer for the Royal Ballet. The main characters encounter each other again five or six years later when company tours the U.S. and the first stop is DC. I mostly skimmed after this point but they got back together. This was a case of being fooled by a cover, the failed, second-chance marriage trope has been done so well in so many other books, unfortunately this wasn’t one.

A hard road to happiness

Ms. Cross did a heartfelt plot. It has a lot of emotions throughout with a lot of obstacles in this couple's journey. The downs far out reach the ups initially.

The characters are so real. Cassian did a lot of growing and changing over the length of the book. Thank goodness cause he was an obnoxious jerk at the beginning.

I highly recommend A Sinful Gravity. You'll start it and not want to put it down.

😐😐😐

I had to stop reading this book. Though Luna and Cassian were still legally married, he practically raped her twice. Once when they were still living together which I'm assuming when Laylah was conceived. The other time when she came to Washington to perform when he came to her apartment. If he can act like this with his wife still, how can they stay married especially with a daughter in the mix.

Ugh! So much promise

Honestly I hate when I DNF a book. I really tried but I just really didn’t like the MFC. Honestly the MMC was a jerk, but I felt she was a b.@&$ with regard to him and his daughter. And I was disappointed in his sister too.

it would be good if it wasn’t for Chloe

She meddles too much and literally treats her brother like sht. For once, she could have sided with HER BROTHER. But no, every time she talked to him, she made him seem like scum. I get it he messed up but nope, she just pulled against him.

I hated Luna and Chloe!!! She was upset that he got angry when he found out about the baby. How dare he!!! He didn’t think about how hard it was for me? Ma’am are you ok?

I have never in my life read dialogue as bad. Never. Every word each character spoke was like an AI Fruit script.
