Awesome story but…
Format: Kindle
The first half of the book needs a lot of editing. Normally I wouldn’t mind but there were a lot of mistakes.
If you take that out of the equation, it’s a solid 4. But this as it is for me is a 3.5
The story is somewhat unique and it brought emotions in the second part.

Dark Romance - Small Town - Suspense - Enemies to Lovers
Format: Kindle
I'm soo glad I read this book. Maddox plays the big tough man with a hard exterior wall. Meanwhile, Evie, who was always stronger than she thought, broke down all his walls. Like true enemies to lovers, Maddox and Evie got under each other's skin to the point they collided and explosions went off...literally. The banter in this book, yeah, chef's kiss. This book has offers a lot. Each character has their own flair to them. Each one showed a level of growth and depth. Sometimes when I read certain books, it feels like I'm just getting the shell of what could have been. Not this one. Tuesday brought the fire. Every human emotion possible I felt while reading this book. I screamed, laughed, cussed, rolled my eyes, and sobbed. Seriously, for all those who love dark romance books with a plot and an excellent characters, this one's for you. Oh - the SPICE be SPICING.

Cute small town and found family.
Format: Kindle
Evie and Maddox’s story was so sweet. Obviously there were many parts that I wouldn’t call sweet, but overall it was a cute love story.
I thought the author did a great job with the Grumpy X Sunshine trope. Cause Maddox is def a big ol grumpy.
The found family trope is so strong in this book and I think that might be my fav part!
Were there a few parts that Maddox made me realllllll upset? Ohh yes absolutely. In reality tho, that almost made him more believable. In no way am I giving an excuse for how he used her trauma against her. Cause that was absolute trash. But I did enjoy him spending the rest of the book attempting to make up for it. He could’ve groveled more tho lol.
I absolutely loved the twins relationship with each character in this book. I think they were so important to the story and added that extra bit. How they protected their mama so fiercely was everything.
It felt like some of these scenes were just thrown together. Meaning, some details were just dropped in but no other context with it. Like tidbits of info that didn’t really go with any part. Other scenes were clearly thought out with so much detail.
The storyline was really interesting. I enjoyed that the FMC/MMC were able to show their trauma and grow and heal from it. I loved how the author showed the MC’s were able to live outside of their trauma and be who they are, not who the trauma made them.
I think this was a very good debut novel depicting just how common the cycle of abuse can be, but even more so how you can break out of it. Not all homes are filled with love and understanding, but Evie was bound and determined to have that in her home.

Please do yourself a favor and read it!
Format: Kindle
So I saw this book on Instagram from someone I follow and was immediately intrigued. And let me tell you I am so glad I picked this up. I literally could not put it down and read it in a day. I am absolutely in love with evie and Maddox. I mean seriously Maddox 😭 I love him so much and that poor brute has been through so much but is just the most lovable thing. And Evie ugh that woman has been through it but is so strong. Every side character in this book is just as amazing too. The twins, Vic, Lou, and don't even get me started on the other Wilder boys😍 this book had everything, it's emotional, heartbreaking, thrilling and just an all around amazing love story. This will be a book I definitely re-read and I don't do that often. Also need to buy a physical copy like ASAP. But what I really need is Mercy's story like, yesterday. He is absolutely my favorite side character in this book and I will be so sad if he doesn't get his own story!

Grumpy Sunshine, Small Town Romance
Format: Kindle
ARC Review 3.75 ⭐️, rounded up to 4 ⭐️’s.
I really enjoyed the book and think the author did a good job of drawing her readers into this couple’s world. The characters were complex, but well developed. Even the side characters were amazing. The setting of the story was well thought out and came to life on the pages. There were definitely some plot twists that I didn’t see coming, and some that were anticipated, but with the way they were timed I was still shocked when it happened. And while this wasn’t the spiciest book I’ve ever read, the spice was definitely there. When it hit, it hit hard!
Overall, I really enjoyed Evie and Maddox’s story. There were some things that seemed repetitive and that could’ve flowed better for me, and there were errors that a good editor should have caught. I definitely look forward to more books from this author though and am thankful for the opportunity to ARC read this book.
This is a book you definitely want to check the trigger warnings before starting. It is packed with trauma and subjects that could be difficult for some readers.
Tropes in this book include:
Grumpy/Sunshine
Small Town Romance
Curvy Single Mom FMC
Broody Hermit MMC
