FMC PMO
Format: Kindle
I just felt like two things
1. The character development wasn’t there the character consistency wasn’t there, especially with the FMC.
2. The FMC would literally make the guys feel bad and keep bringing up that they don’t want her there, but then her whole thing has been. I don’t wanna be here so either you wanna be there or not but if you give off vibes that you don’t wanna be there people are not gonna want you there.

Kiss
Format: Kindle
Was a great read. What a fantastic Hidden Gem I hope doesn't stay hidden. This was a great darkest reverse harem. The FMC was kidnapped in abuse in her past her and her mom are staying on the property of a different Mafia that uses Greek names. Hiding there for safety. The only person that knows is the leader's wife who is friends with the fmc's mom from high school.
The FMC gets involved with the leader son and his two friends. They're all written really well Aries definitely stands out he's a really well-written great character. But I like them all. There is some other woman drama, so heads up there. But I would call this like a medium burn. They get together this book and there are some spicy steamy scenes. But I'm really here for the plot the plot is great the characters are great. I kind of had a feeling of one of the thing is going down from the title of the next book and just a feeling that I got. There are multiple povs it's more the fmc's point of view but we got the guys povs only need them which I really liked.
I really love the story it's really enjoyable I'm so excited for next book and I'm really excited to see that the authors would be putting out a book every month after this book I can say I'm excited to read anything that she writes I'm hoping they're all RH.
There were some like typos spelling errors but it did not hinder my reading experience. Just Small Things having someone do a once-over on could pick up. But honestly like it's is a five-star read in an extremely impressive debut and even if it wasn't a debut I would say it's impressive. It's hard to balance a story with this type of feel a lot of times I think it came out really well and I'm completely enthralled I can't wait for more highly recommend

Run little rabbit
Format: Kindle
Though a familiar trope, it had these teases of intrigue that are enough to keep the story interesting to pull the reader to keep reading, to invest in the plot. Enemies (bullies)-to- lovers, mafia, and RH tropes are all so overworked that there is very little new in the way of a storyline. While I can't say this story is utterly unique, I found myself enjoying the characters and their dynamics together. I look forward to seeing how things go from here between the guys and Emmy, and even how Paloma will fair.

awesome
Format: Kindle
I’ve never read a book by this author before, but she knocked it out of the park! Thanks so much for thinking of us readers who are left with book hangovers and just need the next book in the series. I just downloaded the next one. I don’t normally write reviews but this author needs to be out there so everyone can find her. Great book, excellent characters and pacing. Wonderful storyline.

pleasantly surprised!
Format: Kindle
So, I’ve been on the Find Me (WITSEC) book train and trying to find a book to hold me over until the second book comes out and omg now I’m going to have to do the same for THIS book!
I was drawn in from the beginning. The characters, the multi POV (which is one thing WITSEC lacks), the world building! Excellent! I love a good grovel and I think these guys are headed that way now! I can’t wait to see where the next book takes these characters!
Now….what do I do while I wait?
