Darkness of Mine

Rate this book
*Spoilers for books 1 and 2 ahead - I highly recommend you go back and read Killer of Mine and Secrets of Mine before reading any further.*

She used to work for the FBI… Now she’s the one hiding from them…

Freya should finally be free. Safe. But her life is rarely that simple and the Cross-Cut Killer case is far more complicated than anyone realized. Now, it’s more personal than ever and the killer is determined to make Freya's existence a living hell. She did what he wanted, she ran from the men she loved and now it's slowly killing her.

Hiding out with her pseudo-sister Carmen may be a temporary solution but it won't heal the trauma she's been through and River, Jude, Eli and Oz aren't about to let her suffer on her own.

They're coming for her, whether she wants them to or not, and Freya is left with no choice. She can't avoid the guys forever, not if she wants to catch the killer, because it turns out he's not done hunting and this time a little girl's life hangs in the balance. Darkness of Mine is a full length, mature, New Adult romance with morally grey characters, forced proximity, darker moments and on the page spice. It is a why choose romance, meaning the main character has more than one love interest. This is the third and final book in the Of Mine trilogy. Please read the trigger warnings.

I am OBSESSED with this series, but this final book was missing so much of what I loved about the other books. We have a different threat in each book, and this one felt the most lackluster and dangerous to me, especially since he wasn't actively even really going against our main characters? I just felt like there wasn't a ton of urgency against the threat, so we really just followed the heroine kind of hanging out and handling her own trauma she's uncovered. And there was A LOT of spice that didn't help further the connections or the plot for me, and those two things are what I need to really enjoy the story. As the conclusion to the story, I just wanted the highest stakes in the series and it fell a bit flat for me.

I feel bad for Allie. I wish she had her own HEA. Though this book seems a bit rushed, I enjoyed it immensely. Really want a series on Carmen next.

Thank you Alexis Grace and Grey’s Promotions for the ARC in exchange for my honest review.

Unfortunately, this finale didn’t land for me. The first book had a great balance of danger, suspense, and emotional intensity, but this one tipped too far into spice-heavy drama.
The FBI angle—one of the strongest parts of the series start—felt almost laughable here. The characters made rash, unrealistic choices, and every serious moment seemed to get undercut by sex. It turned intimacy into a replacement for character growth, which kept me from connecting with the story.
The villain didn’t deliver the psychological impact I was hoping for, and while there were bursts of tension, the pacing dragged until the very end. By then, the resolution felt anticlimactic.
That said, I think readers who love heavy spice and protective MMCs might still enjoy this. But if you were invested in the thriller aspects and wanted real emotional payoff, you’ll likely be let down.

The first book, 𝐊𝐢𝐥𝐥𝐞𝐫 𝐨𝐟 𝐌𝐢𝐧𝐞, didn’t fully win me over — the mystery hooked me, but the romance fell a bit flat. The second book, 𝐒𝐞𝐜𝐫𝐞𝐭𝐬 𝐨𝐟 𝐌𝐢𝐧𝐞, was the best in the series for me, balancing investigations, character development, and a much stronger love story. The third book, 𝐃𝐚𝐫𝐤𝐧𝐞𝐬𝐬 𝐨𝐟 𝐌𝐢𝐧𝐞, I liked it a little bit less than the second, because we had less FBI and more romance, and it’s totally okay (because we read why choose for the spicy scenes and romance lol😁). Still, it delves deeper into Freya’s trauma and her journey toward trust and love. And the relationships with the guys became deeper and more meaningful, so I really enjoyed the love plot.

When I found out I was getting this arc, I screamed. Thank you to Grey’s promotions and Alexis for this honor.

The pain, the raw emotions, the happiness that radiated of these pages, changed me forever. Freya, Jude, Eli, Oz and River have a permanent spot in my heart. With some books I notice every page I turn, how much time I spend reading them, but with this book, all that disappeared. There’s just me, and the story, I flew through the pages and everything else just vanished. I did want to put my book (read: phone) in the freezer at some point, but all’s well that ends well.

This series is now one of my favorite series of all time 🖤

Emotional ending!
What a rollercoaster these books have been 😅 I have really enjoyed the premise of this trilogy with our FMC being the daughter of a serial killer with her fighting the way she was raised and training to be a good person! Honestly Freya is one of the strongest FMCs I have ever come across 🥰 she’s selfless beyond belief and will do anything to keep her loved ones safe! You see her learn more of her past in this one (please check your TWs!) especially with the new murderous relation Freya has uncovered and his unnatural obsession with her 😖 it twists her and you see her go through that journey to find herself again 😫 on top of that her men each have to deal with the fallout from her sacrifice and it’s not pretty! There’s a lot of tension and angst there to work through for River and Jude, whereas Oz is grateful and Eli has a lightness that must just be the only thing keeping them grounded 😱 although an emotional one there are spicy scenes between them, and they definitely pick up in spice in this one! In terms of pacing i felt the ending seemed to go very quickly compared to the majority of the book but other than that all the loose ends were tied up well with a heartfelt HEA to this great dark RH trilogy 😌

I was fortunate enough to be an ARC reader for this release.

I have been looking forward to the last installment in this series, and I think Alexis Grace did a great job in how it was ended.

This book was packed with emotion and suspense, and I think AG did a great job guiding us through a roller coaster, while allowing us to experience every emotion alongside the characters.

The plot was good, and the development of the story and characters felt natural and effortless. Alexis Grace did a great job in writing a satisfying and realistic ending, while typing up all the lose ends in a believable way.

What an ending to a perfect series! We left off on a major cliffhanger from Secrets of Mine and Darkness of Mine pretty much picks up right where we left off. Where did Freya go? What is Zach going to do next? Will she ever reunite with the guys?

I’m not going to spoil it for you, but it’s a romance so there is a HEA.

I loved diving into some of the guys past traumas to help explore what made them them, and how they work through healing. We also saw some more Carmon and I have a sneaky suspicion she’s getting her own story with Jack and Reaper.

I laughed. I raged. I loved. I cried.

This is a Roman Empire series. Please, I beg, read this and thank me later.

OMG!!! What a bittersweet ending to an amazing trilogy. It has EVERYTHING. Mystery element, new found family, a badass FMC trying to overcome her trauma, and SPICEY 😂❤️ I would’ve finished it in a day if my adult life wasn’t getting in the way. Book was the perfect length and I’m truly sad it’s over.

This was an incredible conclusion to this series! I’ve been anticipating this since the diabolical cliffhanger we got at the end of book 2, and it did not disappoint!

If you’re a fan of Criminal Minds and why choose romance this is the perfect series for you! This book was spicier than the first 2 books but still maintained that good plot to spice ratio. This whole series was action packed from the first book to the last, and made them all so easily binge-able.

This conclusion was emotional, and the character development throughout the entire series was phenomenal. Freya’s growth especially, every character brought their own trauma to the table and grew through it. I did see we’re getting a spin off, and I have an idea of who it may be about, and I’m so excited for it!

Thank you so much to Alexis Grace and Grey’s promotion for allowing me to read this pre-release in exchange for my honest review.

I reckon I had high expectations. And they were not met. Freya was a mess, River was unbelievably controlling (to the point that I firmly believe they’d break up in less than a year). The other guys were meh. The plot with the brother and the cult didn’t really develop. And I knew something would happen to Allie, I just knew.

🎶 “And the last thing you wanted.Is the first thing I do. I tell you my problems. You tell me the truth” 🎶

Freya (h) should finally be safe - but safety is an illusion, and the Cross-Cut Killer isn’t finished with her yet. Forced into hiding and torn from the men she loves, she’s unraveling under the weight of trauma and secrets. But River, Jude, Eli, and Oz (H) refuse to stay away—especially when a little girl’s life is now at stake. The killer is still hunting, and Freya is done running. To stop him, she’ll have to face the darkness head-on… even if it destroys her.

Thank you to Valentine PR for the ARC in exchange for an honest review.

[River]

River definitely went to some extremes in this one to keep her safe. Some of the things he did might come off as over-the-top or even controlling, but you can tell it all came from a place of love and concern. One of his choices, while intense, actually ended up being super helpful in the end. He didn’t really see the issue at first, but once the others called him out, he started to get it. Overall, his heart was in the right place, even if his approach was a little much.

[Jude]

Jude had a major shift from the first book to now. He went from being the sweet, sunshiney one to a lot more guarded and moody. But honestly, it all came down to feeling hurt and abandoned when she left. He didn’t fully understand why at the time, and it definitely changed how he treated her. Things didn’t really start to turn around until they had a really emotional moment that brought everything to the surface. After that, he started to open up more, admitted some of his mistakes, and finally began to see things from her side. It was a big moment for his growth.

[Eli]

Eli had some of the best character growth in this book. He went through a major turning point that completely changed his vibe - and honestly, it was so refreshing to see. After carrying a lot of heavy stuff from his past, something finally clicked for him, and it was like a weight had been lifted. From that moment on, he had this playful, carefree energy that totally lit up every scene he was in. He went from intense to golden retriever puppy energy, and it was everything. Funny, chaotic, and just a joy to read—he really became the heart of the group in a way I didn’t expect.

[Oz]

Oz had a really honest and kind of unexpected moment in this book. He straight-up said he didn’t blame her for leaving (book 2), because she did it to protect someone he loved and that really said a lot about him. Even though he’s usually more reserved, it showed how deeply he still cared. He was totally on board with some of the more protective (borderline intense) decisions being made, but it wasn’t about control—it was about love and worry. You could tell how much he felt for her in the way he always wanted to make sure she was safe. It was actually really sweet in a rough-around-the-edges kind of way.

— ⋆。゚☁︎。⋆。 ゚☾ ゚。⋆ OVERALL⋆。゚☁︎。⋆。 ゚☾ ゚。⋆—

Overall, I really enjoyed this book because of how protective the guys were. Their loyalty stood out -they cared deeply for her and never gave up, no matter how many times she tried to push them away. They just wanted to keep her safe, even if it meant taking extreme measures. That kind of devotion really hit me, and it was clear they were in it for the long haul. That said, the story itself felt a little all over the place. The emotional stakes were high in the previous book, but this one lost some of that momentum. The plot kept shifting directions, and I found myself less invested in the new conflicts. It just didn’t have the same impact, and by the end, I wasn’t sure what the main focus was supposed to be.

Warning: This review may contain spoilers for the first two novels in the Of Mine Trilogy

Darkness of Mine continues the saga of Freya (identical twin and tortured / tormented daughter of the recently vanquished Cross-Cut Serial Killer) and her reverse harem FBI team (the steely and staid River, gentle-hearted hacker Oz, brilliant and introspective genius Jude, and brash, impulsive, wise-cracking, cowboy, Eli) as they face off against their final enemy: Freya's older half-brother and son of a cult leader, Zach, a pedophile, who briefly masqueraded as a cop, is fixated on Freya, and has taken to kidnapping young girls who look just like Freya to taunt her.

When the novel begins, Freya has left her men in favor of her friend Carmen's safe house, in hopes that doing so will protect them from Zach's wrath. This causes the FBI team to go to controversially extreme measures to get her back into their waiting arms, and keep her there, even potentially against her will.

Will Freya and her men be able to heal their individual wounds, as well as those newly formed by her recent departure and forced return? Will the FBI Team be able to track down Zach and rescue his young captive before he strikes again?

On a positive end, having not read Book 2 in this series in quite some time, I appreciated how surprisingly well this novel functioned as a standalone. With the Big Bad from the first two books off the board, Darkness of Mine essentially functions as its own procedural novel, with helpful expositional dumps along the way to reorient readers, and keep them from getting too "lost in the sauce" narratively speaking.

I also appreciated Darkness of Mine as a character study. Free from the heavy plot / mystery building of the first two novels, Book 3 is able to really settle in and delve into the hearts, idiosyncrasies and hangups of our five main characters. Freya, River, Eli, Jude and Oz are all a bit broken and traumatized by their pasts when the novel begins. Throughout Darkness of Mine we get to see each character grapple with their past traumas and work toward healing.

In addition to giving each character their own journey and arc, Grace also takes time to explore Freya's distinct relationships with each of the men, healing those as well, following the damage her departure caused to them. Yes, a lot of that is done through some fairly creative sex scenes. But I did appreciate how Grace managed to create separate emotional and intellectual connections between these characters too. As a result, each of the five pair-relationships felt fully realized by the end of the series.

I found the final climactic battle scene and its heartbreaking aftermath to be genuinely effective too. This portion of the novel kept my interest, and ultimately provided me with solid closure to this series.

I eventually settled on the 3.5 star rating, because, while I appreciated these aforementioned aspects of the tale, I didn't entirely feel this novel was necessary to the series as a whole. The Zach character felt a bit like an afterthought following the intrigue, complexity and terror presented by Freya's father and twin sister. With the team very slowly tracking down one man, who kidnapped one girl, the stakes definitely felt much lower in this story than in the prior two. This resulted in a lot of wheel spinning and surprisingly little plot.

I feel as though Grace may have killed off Freya's father too fast. Had his arc been extended to the third book, I feel as though the same character beats and ultimate climax could have still been utilized here, with the plot, tension, horror, and high stakes more evenly spread out across the three novels.

That said, I'd be willing to give another Grace series a try, particularly, if she opts to further explore the Carmen, Jack, and Reaper characters, who were set up so nicely here as a future throuple!

This trilogy has been such a strange reading experience for me, because I’ve consistently had two very different reactions happening at once.

The murder mystery / serial killer / investigative chaos of the first two books were full-on five-star levels of addictive for me. The mind games, the pacing, the reveals, the constant sense that something uglier was waiting under the floorboards…that part of the first two books absolutely worked.

The reverse harem romance? Much more miss than hit. Honestly, closer to two stars for me at times.

So going into Darkness of Mine, especially after that huge cliffhanger, I expected the mystery side to go fully feral. I expected the finale to be the most twisted, high-octane, mindfuckery-heavy part of the whole trilogy. And weirdly, that’s not quite what happened.😂

For me, the murder mystery was actually the part that fell a little flatter here.

Not badly. Just flatter compared to the first two books. The previous books had this propulsive “what the hell is happening?” energy that kept surprising me. This one still has danger, still has missing girls, trauma, cult threads, family horror, and a finale with real stakes. But the investigative tension did not feel quite as sharp. It felt more clear-cut, more emotionally focused, and less twisty than I expected from the final book.

At the same time, this is also the first book where the romance side finally settled enough for me to connect with it more.

Still not perfectly. This is not my favourite RH dynamic, and I do think the individual relationships could have used more depth. River, Eli, Oz, and Jude all have their roles, their wounds, their specific connection to Freya, but I still sometimes wanted more emotional specificity between each pairing.

But this time, the group dynamic made more sense to me. Freya’s absence creates a genuine emotional rupture. The guys are not just possessive shadows orbiting her; they are angry, scared, spiralling, and forced to confront what loving her actually means when control is not the same as safety. The book even makes River’s darker need for control part of the conflict instead of pretending it is automatically romantic, and that helped a lot.

Freya was easily the strongest part of this book for me. I liked that the book gave her space away from the men, because she needed to exist outside their orbit for a while. The therapy angle, Carmen’s hideout, Rebekah and Samuel, the baking, the ugly coping mechanisms, etc. all of that made her feel more like a person trying to survive herself, not just the centre of a murder plot and four men’s obsession. I needed to see this!

And I think that’s why this is the strongest book of the trilogy for me, even though the mystery was not the strongest. It finally balances the two halves a little better.

A messy but satisfying finale, and definitely my favourite of the three.

With Darkness of Mine being the final book in the series and me absolutely loving the first two books, I went in with pretty high expectations. I really wanted to love this one, but unfortunately it just didn’t hit the same way for me. 😭

What I loved about the earlier books were the intense plot twists, the gripping storyline and the way everything constantly had me on edge. Those moments had me shocked, invested and completely hooked. In this Darkness of Mine it felt like the plot took more of a backseat and the story leaned heavily into the spice. Don’t get me wrong.. I enjoy some smut in my books but here it felt a bit overdone and at times like it replaced the depth and tension I loved before. 🥹

I also think my expectations played a big role. The first two books ended on major cliffhangers, so I was really hoping for a powerful, explosive conclusion. Sadly it didn’t quite deliver that “big bang” feeling for me.

That said, it wasn’t all bad. I still love the characters and the “world”, which is why this wasn’t a lower rating. I just wish the balance between plot and romance had been closer to what made the earlier books stand out to me.

⚠️SPOILER WARNING BELOW⚠️

There were a couple of scenes that really didn’t sit right with me:

1. The moment where River (I think it was him, but I might be wrong) finally finds Freya after searching for so long. I understood his anger, but instead of any emotional reunion, the scene immediately turns physical in a very abrupt and rough way. He bends her over and just takes her? No lube, no warming up, no foreplay. It felt if I have to be honest uncomfortable. 😳

2. The scene where Jude comes back from the hospital and finds Freya asleep in his bed and then puts his 🍆 in her while she’s still sleeping because he “wants to be close to her.” That just didn’t work for me at all and really took me out of the story.

Overall I’m sad this didn’t live up to what I’d hoped for, especially as the finale to a series I’ve really enjoyed. Still I’m glad I read it and got closure on the characters journeys even if it wasn’t quite the ending I was looking for.

But with all of that being said, I’m excited to see what Alexis Grace has for us in the future. 🖤

This book absolutely blew me away.

Going in, I already knew it was going to be fantastic (it’s Alexis, how could it not be?), but this? I wasn’t ready. The suspense, the pacing, the emotional punches, everything hit just right. There wasn’t a single moment that dragged. Instead, it kept me flipping pages like my life depended on it.

And let me tell you, I felt a lot while reading this book. I laughed, I got all hot and bothered (👀🔥), and yes… I cried. More than once. It takes a special kind of author to pull all that out of me in one story.

Let’s talk characters in DOM:
• River… oh, I wanted to strangle you at first (seriously), but you redeemed yourself and then some.
• Eli, baby, you’ve changed, and I’m SO here for it.
• Jude… we got you. We love you. Protect Jude at all costs.
• Oz, sweet Oz. That heart of gold… and that mouth of his 👀🔥.
• And Freya. Oh, Freya Darling (/ Kitten / Mo Leannan / Angel), you’re a straight-up badass, especially by the end. I want to be you (okay, maybe not everything you went through, but still).

This finale was everything I wanted and more. Alexis truly delivered a powerful, unforgettable end to an incredible trilogy. I’m honestly obsessed.

I will forever recommend these books to everyone. Try and stop me.

Auch. Decir adiós a esta gente ha dolido.

Sigo llorando porque ha habido un giro que no he visto venir que ha ido directo al corazón como una puñalada. Y aunque ha sido el más apurado de los tres creo que en conjunto toda la trilogía es maravillosa.

El viaje que hacen estas cinco personas. Como Freya se va abriendo a los chicos, dejándoles ver sus inseguridades y miedos y como ellos cada uno a su manera la ayudan a salir de esa espiral en la que estaba y a verse como la guerrera y superviviente que es… es que eran almas destinadas a encontrarse.

Ojalá hubieran más epílogos para verlos en el futuro eso si ahora necesito también la historia de Carmen.

Estos cinco agentes del FBI siempre tendrán mi ♥️ Nunca me cansaré de recomendarlos.

Saying goodbye to these people was like being stabbed in the heart. What a trilogy, and how beautiful it was to see how River, Oz, Jude, Eli, & Freya were destined to be together. How they love, care for, and protect each other. Thanks so much for the ARC, they'll always be my protégés

"I may collar you, but you have my heart on a leash."

Okay. So. I have not been breathing for majority of the last 20% of this book. I have been sobbing like a baby though.

This book was the perfect end to this rollercoaster of a trilogy. So much heartbreak, love, devastation and insanity all wrapped up nicely with a bow of twists and turns.

I was once again not prepared for where this book took me but I enjoyed every second of it. The story evolved insanely with some great plottwists and surprises and I wish I could reread the series right away.

Freya, Allie, Jude, Oz, Eli, River and even Carmen will hold a special place in my heart ✨🤍

The guys are an absolute WRECK with Freya being gone and it just shows how down bad they were for her. “Don’t worry darling, you will” oh man this line gave me SHIVERS 🙂‍↕️

Freya really pissed me off in this book. In Killer of Mine she was a super strong fmc and I feel like as the series continues on she was becoming less of a badass. Common sense? GONE. Survival instincts? YEAH NAH. Her love declaration for the last guy (I don’t want to spoil who it is) felt so forced I feel like she could’ve done so much better. How was he last to get one? 😭💔

I was super close to DNF-ing but because it was an ARC, I pushed through. I’m glad I did. This book shows that all the characters have flaws and how important it is to heal from trauma.
Also a book with short chapters is seriously under appreciated. This book was fast paced and I never felt bored. The date night scene at the table was STEAMY I loved it omg 🥵🔥 And the little plot twist?? Oh my god was my heart was racing like crazy in this book.

I really recommend the series. It’s thrilling, gripping, bloody, dark, and spicy. Romance did take a little step back and the guys did kind of blur together in this book, but overall it was a satisfying (but sad) ending to the series.

Thank you so much Alexis Grace and Greys Promotions for this ARC

This was a satisfying end book. I liked how this wrapped up and it did make me cry because a certain part was just so sad. The reason why it’s not a full five stars is because I thought there was too much focus on River and not on some of the other love interests. Like I think Jude deserved more page time. Also I just did not like how River was acting. There’s so incredibly dark themes throughout so just read the trigger warnings.
