The first few chapters were a little slow and I couldn't really connect with the story, but it was cute.

౨ৎꨄ︎ 3.5

cute, fun story and the summer vibes are on point. but the chemistry between the characters? non-existent.

the introduction to the story and the build-up is great. whilst i found some things unrealistic (like for instance why was she set on only that one club and didn’t plan to search for a job somewhere else?), i did enjoy how isabel's journey in ibiza started.

r.s. grey didn’t just focus on romance, but friendship and coping with grief are huge parts of this story and what a beautiful journey it is! i enjoyed isabel’s relationship with her new friends, how it not only helps her with her plans and hopes, but it also pushes her to realize how unhappy she truly is back home.

i actually liked isabel as a character. she might come from a rich family, but she’s so tough and sassy! she’s obviously still struggling with the loss of her sister, but i love how she honored her through the bucket list.

whilst i find cristiano hot, caring and very ambitious, i feel like layers still remained that should have been peeled in order to get to know him better. it's not just the limited povs, but i feel like not even isabel knew him that well? also not the biggest fan of his overprotectiveness. yes, it's important when men care, but his actions were sometimes too much.

which takes me to their relationship. the moments they spend together are definitely beautiful and romantic. but why does their relationship feel like an insta-love? there’s banter (which is fun), but then suddenly they’re almost like a couple. their relationship had potential, but needed a deeper connection.

i also found the ending a bit rushed. the pacing of the entire book is great and it's easy to read, but the ending had a potential to be a bit better.

but i still really enjoyed this story and some moments. it has beautiful scenes and setting, perfect for summer reading. definitely recommend if you’re looking for something cute and quick!!

This is going to be a long review, so buckle up lol.

I’ve been a huge fan of R.S. Grey for years, and she’s honestly what got me into reading in the first place, starting with Scoring Wilder back in 2014, so I was really excited going into this one.

Our Secret Summer has everything I love about her writing. The tension, the enemies to lovers dynamic, the setting, the characters… it all just worked so well for me.

I completely fell in love with Isabel and Cristiano. Isabel’s storyline was especially beautiful. Watching her travel to Ibiza, not just to escape her life but to complete her sister’s bucket list, added such an emotional layer to the story. It wasn’t just about romance. It was about grief, healing, and figuring out who she is outside of the life she’s always known. Seeing her slowly open herself up to new experiences, new places, and new people made her feel really real and easy to root for.

And then there’s Cristiano. I loved how guarded and off-limits he felt at first. That dynamic between them, especially with him being her boss, created so much tension right from the start. Their relationship had that perfect push and pull where you could feel the chemistry building in every interaction, even when they were trying to resist it.

And the romance… the slow burn was SO good. The tension between them was insane in the best way, and it just kept building and building. Every look, every conversation, every moment felt intentional. And when it finally paid off, it delivered. The chemistry, the buildup, the spice… all of it hit exactly how I wanted it to. It felt earned, not rushed, which made it even better.

I also loved how the setting played such a big role in the story. Ibiza felt like its own character. The nightlife, the scenery, the energy of the island all added to the vibe and made everything feel very immersive and very summer coded. It made me want to be there with them.

I found myself highlighting so much throughout the book, which is always a sign I’m fully invested. There were so many moments that just stuck with me, whether it was emotional, romantic, or just really well written.

Overall, this was the perfect summer read and exactly what I want from R.S. Grey. It had the fun, flirty energy she’s known for, but also had more emotional depth than I was expecting, which I loved.

If you love enemies to lovers, strong tension, emotional character growth, and a slow burn with a satisfying payoff, I would 100% recommend this one.

It isn’t often that I have a physical reaction to a book, but this one? There were definitely tears streaming down my face by the end… happy tears.

So grateful for the complimentary copy sent my way from NOVL because I genuinely might have missed this one otherwise. I ate this book up in a single day. I was completely swept away by the escapism and how perfectly it hit all the romance beats I love.

Millionaire/Billionaire Romance ✅
Vacation Romance ✅
Feisty FMC ✅
Dark, brooding MMC ✅
Plot-driven, non-cringey spice ✅
Found Family ✅

And that’s just scratching the surface.

What really stood out to me was the balance between the FMC and MMC. Neither of them needed the other in a dependency sense—there was no damsel in distress, no over-the-top “rich man fixes everything” dynamic. They both stood firmly on their own, which made their connection feel that much more genuine. It was about want, not need, and I will always eat that up.

If I had to nitpick, I would’ve loved a bit more depth when it came to Cristiano. I want to know who he is beyond the business, what really drives him. But at the same time, that slight mystery added to his allure and absolutely kept me turning the pages (which I happily did at lightning speed).

And let’s talk about the spice for a second… because yeah, there is spice, and it was completely in line with what I enjoy. It’s entirely plot-driven, never gratuitous, and hits that perfect balance of being exciting without tipping into cringe. Every scene felt intentional and connected to the emotional growth of the relationship, which made it land so much harder.

My only complaint? That I didn’t read this sooner.

Opinion Breakdown
The Good: The premise, the side characters, the H.

The Not-So-Good: The h was too immature for who she was supposed to be IMO.

The Bad: The ending. I felt like it was too abrupt and didn't leave me with nearly enough closure.

Overall: This was cute! I was going in writing this review thinking it was going to be 4 stars, but then once I started voicing my struggles with it, I went down to a 3.5 star review. The ending is the main reason (see closure section below). Then it's the h. I struggled with her being a 26 year old with a MBA that had to hide things from her parents. She also was rude to the H at first in a way that felt like it was supposed to be cute. I felt like she behaved immature and didn't quite get the "overly responsible" characterization of her. All that being said, I didn't hate it or anything and I still enjoyed it a good bit.

Brief Summary of the Storyline: This is Isabel and Christiano's story. Isabel decides to take a trip her sister was planning and scratch off the bucket list items she created before she died. Only she has to go incognito because her protective and famous family doesn't know what she's planning. She instantly meets some friends and also keeps on running into her new boss, Christiano, and sparks fly. There are some sweet moments, some secrets revealed, some sexy times, and some fun side characters...and they get a HFN ending.

Point Of View (POV): This alternated between Isabel and Christiano's POV.

Overall Pace of Story: Good until the end. I never skimmed and I thought it flowed well otherwise.

Instalove: No, but instant attraction.

H (Hero) rating: 4 stars. Christiano. I liked how he reluctantly fell for the h and was instantly in protector mode.

h (heroine) rating: 3.5 stars. Isabel. I liked her, but I also thought she was a little immature for her age/life experience at times.

Sadness level: Low, no tissues needed

Push/Pull: Not really

Heat level: Good. They have some good tension, chemistry, and scenes -- but not so much it takes away from the story.

Descriptive sex: Yes

OW (Other Woman)/OM (Other Man) drama: Only some mild jealousy

Sex scene with OW or OM: No

Cheating: No

Separation: Not in the typical sense

Possible Triggers: Yes

Closure: This ends way too abruptly for me. All of a sudden we have a time jump in the epilogue and barely any closure right after the conflict was "resolved"?! Yeah, that was disappointing for me and while others might be fine calling it a HEA, I consider it a HFN

Safety: This one should be Safe for most safety gang readers

All I have to say is that on page 241 the mmc says “I’m glad you’ve been kept up on that shelf, waiting for me.” And I almost vomited lol I simply MUST stop letting sprayed edges fool me.

since it was my first day of summer vacation, i kicked it off with buying 13 romance books

and this was one of them, and it was decent. i liked cristiano but I thought of Ronaldo the entire time kinda bc he was Spanish

i think her parents had an appropriate reaction to her lying about being in France when her grandmother got hurt (but her grandmother lied to her parents for her so i don’t really think it’s entirely Isabel’s fault)

okay now im gonna read another romance bc its summer

I had to suspend belief but also kind of a great summer read?!! It was dumb and flirty and not too long. We really missed an opportunity for a great dancing scene though. I think it was like 2-3 🌶️

Secret Summer 💙

Love that Elle decided to take a risk & stepping out of her comfort zone. That her secret turns into friendship & love.
Sometimes taking a leap of faith (or jumping off a cliff in Ibiza) will help free your mind & open new doors...

Definitely not the best or worst book I’ve read. I do love when there isn’t a third act break up and when the MMC falls first but I felt there was no build up to them being attracted to each other or him falling.

Also if you want a good laugh, listen to the Spotify audiobook. The narrator for Cristiano was quite interesting especially when he had to do a female Australian accent 😂

This was such a cute fun summer read. I loved every minute of it. As an older sister, all the Winnie chapters twisted my heart so hard. I was invested in all the characters. 10/10 would recommend.

these books are a dime a dozen. the characters BLAND, the insta love is cringey, chemistry? NONE. how many times have i read the same book?? i feel like ive read this story 100 times before. The lack of character and development of the story really had me wanting to DNF, but since it was our book club book this month i wanted to finish it. the only reason i gave it 2 stars instead of 1 was because i liked simones character. but yeah overall this sucked, i need some depth in my books and this has 0

Very cute story, with some deeply emotional moments. I loved the overall story, the newfound friendships/family, the setting. Unfortunately though, the romance wasn't as organic and tangible as I had hoped. Still a fun, light read that kept me good company while doing chores and packing for my vacay ❤️ ~ yes, I did the 🎧audiobook🎧 haha. While the female narrator was absolutely awesome, the male narrator was fairly cringe 😬 I would still recommend it though! It is free on Spotify Premium 🫶

well….i’ve officially dnf’d my first book. i thought i could do it, but Cristiana was literally so annoying that i couldnt get passed it. the idea is fun, and i think theres more underlying things that could be explored (such as the rich girl trying to pass as normal for once), but it didnt hit the mark. the relationship is kind of trash and i had to give up. i wish i liked it bc its the perfect summer vibes but lowkey this book is what is wrong w modern romance books!!!

Oh. My. God.

This is a book I was dreading for all the best reasons, I have been a fan of R.S. Grey now for over 10 years, I love her books, and I hate when her books end. I didn’t want to start this one cause then it’d be over, but I’ve been thinking about it daily and monthly since I got my copy. I think this is easily a top five R.S. Grey book for me now, I loved it with my entire body.

The banter between Cristiano and Isabel in the beginning when she gives him an attitude from the first time they met was the literal best. One thing about her background, is she isn’t going to let a man get her down, nor let a man do anything without giving it back, and I loved how much she pushed him throughout the book from the beginning to literal end. The setting of this book was absolutely beautiful, all the books I’ve read set in Ibiza describe it so vividly that I just become desperate to visit, I can so easily picture each scene and it makes the book that much more beautiful.

The spice in this book blew me away, it was some of R.S. Grey’s best, and I was heated and enjoying every moment. The chemistry, tension, push and pull between them just added so much to their desire and connection beyond the friendship also building, I lived for every scene they were in together.

Finally, the friendship in this book between Isabel, Simone, and Annika was so good. I loved the support, the joy, the laughter and just seeing them all get along with no jealously, I’m so glad that R.S. Grey didn’t make the club a toxic place to work, but instead a safe place to land after Isabel hated working for her father’s company.

Man, I’ll be sharing this book with all my friends, I cannot wait to get a physical copy for my shelves!
