Hidden

by Ruby Wolff

He was never just watching.

Sadie Elliot wanted a clean start a gymnastics scholarship, a quiet dorm, a life that finally belonged to her. What she got instead was a stalker who left violets, knew her secrets, and never looked away.

By day he is Miles controlled, brilliant, dangerous in ways she can’t yet see. By night, he is the man she invites into her bed with a mask still on her Ghost. She thinks she is choosing the stranger. She has no idea they are the same man.

Miles has spent years hunting a network that steals girls and sells them into silence. He never expected the next name on their list to be the one woman he can’t stay away from. When Sadie is taken, the carefully separated halves of his life collide and the only way to get her back is to burn everything down.

Some men protect what they love.

Miles claims it.

Some obsessions protect.

Some destroy.

His might do both.

Miles my computer genius has found him a obsession and her name is Sadie. He was obsessed from the moment he laid eyes on her. And Sadie she thinks Miles is hot! Sadie is sweet girl who puts her family before herself. Miles is Miles. I can’t tell you much without giving things away. I will say there is surveillance, mask, flowers and so much more. The book is more plot than spice. If you’ve read the previous books of this series then you know the brothers are apart of the “family business”. And that business called upon Miles and got to hacking. Miles and Sadie’s love story is complicated, how they began is very unconventional. I love how Ruby’s books are a story within a story. What I mean by that is you have the relationship evolving between Miles and Sadie and then you have another plot line of family business. Eventually these two things merge. I love how when a brother finds him a girl, once she says she’s in the family protects her like their own. Now let me tell you about the stress Ruby put me through the last 12% of the book. I’m sweating and stressing. I’m going through it. I was on the edge of my seat. The first half of the book was ok but the last half was something else. I definitely enjoyed this book. It was great. I love Ruby’s writing it so engaging. One of my favorite parts of the book didn’t involve the couple, it was Mason and his bat IYKYK. And that makes me even more excited for the his book(which is next)! Well done Ruby, I’m excited for what’s next!

What I love about Ruby Wolff is that just when you think you have a favorite male character, she manages to change your opinion by writing another one who completely conquers your heart—making you question if you should let your old favorite go and make this new one #1. That being said, after being fully invested in Olivia and Hayden's story, Miles and Sadie came in and took over my top spot, because honestly, who doesn't want an obsessed man/stalker?

What I especially liked is that the author didn't focus the love story just on Ghost and Sadie, but also on the connection between Miles and her. Add to this the mystery involving Miles's missions, Sadie's journey from carrying the weight of saving her brother to finding herself surrounded by friends and a found family, plus the perfect amount of spice, and this is it!

"I made a promise to save my brother, not knowing what it would cost me, but it cost me nothing because now after everything I’ve been through in my life, this is the way I dreamed my life would end up. Happy, a group of friends, and a man who loves me more than anything in the world."

Now I am DEFINITELY ready for Mason Crawford's story and at this point, I'm officially giving up on trying to choose a favorite because Ruby Wolff clearly isn't going to let me keep one anyway!

Thank you, Ruby, for this great, great story!!!

The Crawford family is an extremely tight and lethal one. They perform justice where the legal system fail. They’ll die for each other if they have to. HIDDEN is book 4 of this amazing series and an exact description of Miles Crawford as he’s a GHOST in his human form as well as his ONLINE FORM. An extremely talented hacker Miles stops at nothing to protect the ones he loves. After setting eyes on Sadie Elliot new student and now attending the same college as Miles , he has made her his very personal mission. He has his eyes on her everywhere she goes and becomes obsessed with her enough so that he stalkers her without her knowledge but also protects her . He’s given a mission from a family member where girls are mysteriously disappearing in different states with a precise pattern that lead to a sex trafficker who’s selling girls at auctions. Sadie has been targeted and Miles is the only one who can save her. This very explosive book has all the action, chemistry, twists and turns you don’t see coming but mostly the addictions you crave when reading a Ruby Wolff book. This one is no exception and you’ll crave the Crawfords’ more than you’ll want. A highly recommended reading.

Hidden ( Crawford Brothers Book 4 ) Dark , Steamy , Emotionally Charged and just utterly addictive) that’s exactly what this entire series is . Because guys , words cannot describe how obsessed I am with it . I have to say , I was not prepared for the crazy and wild ride I was just taken on . Sadie and Miles captivated me from the very beginning. All the layers to their characters and the complexities in their story . If you love morally grey MMC’s then your going to love Miles - A hacker at the top of his game , a Ghost who becomes completely obsessed with Sadie from the moment he sets his eyes on her and is determined to make her his . I don’t want to go into to much detail about how this incredible story progresses and comes together- because trust me when I say you need to experience it all for yourself. What I will say is if you love morally grey and dark romances , if you love secrets and intrigue and mystery and suspense, if you love stories that willl keep you guys whe whole way through and will absolutely stir so many unexpected emotions in you . Then you absolutely need to read this book .

Miles is obsessed with Sadie. He stalks her, hacks her and becomes everything she needs. Sadie had grow up fast because of her brother's poor choices. While hiding his identity he becomes the person who tries to take care of her. Sadie tries to fight it but she lost that battle. Things take a turn when a hack job is flipped and the hunter becomes the prey and now Sadie is caught in the middle. True to Miles word, he did everything to protect her. Miles and Sadie's story is done but I'm wondering if the plot continues with Mason? Guess we'll just have to wait and see!

This was easily a 5-star read for me. I was hooked from the very first chapter and honestly did not want to put it down. I loved meeting Sadie and Miles, and I found myself completely pulled into their story right away.

Miles was intense, mysterious, protective, and so much more than just someone watching from the shadows. The chemistry between him and Sadie was steamy, addictive, and full of tension, but the suspense is what really kept me on the edge of my seat. Every time I thought I knew where the story was going, something pulled me in even deeper.

I loved how dark, emotional, and exciting this book felt without losing the connection between the characters. Sadie’s story made me want to keep reading, and Miles had me completely intrigued from the start. This book gave me the steam, suspense, and obsession I was hoping for, and I enjoyed every minute of it.

Sadie is starting fresh at college. Making new friends and meeting new people. She catches the eye of Miles, who is captivated by her. His stalking, spying, bringing her flowers and her favorite coffee while she's sleeping is sweet. haha But she feels the same. She likes being cared for. Miles, one of the many Crawford brothers is the hacker of the crew and what a handsome crew it is. He knows pretty much everything about her and every move she makes.

While keeping an eye on her, he's given a job, the case consumes him which brings chaos to their door. The danger and suspense towards the end keep you on the edge of your seat. I loved watching Miles and Sadie's relationship develop and seeing the brothers in action to protect their family. Can't wait so see what's next with Mason, I love his crazy.

[Karen Boozer · Rating 5 out of 5]

All I have to say is I am a little shocked with what we finally see from Miles! This book had quite a few twists and turns with both Sadie and MIles. There are some dark parts of the book so if you have triggers, please read them ahead of time.

They are actually quite a cute couple when we get to see them as Miles and Sadie. You get to see them as individuals as well as the mystery romance that is there but once Miles comes clean and Sadie realizes you really see who they are. I am not sure I would have been as understanding as Sadie with all the subterfuge.

This book is not without the intrigue and mystery of the previous books although I have only read one other. The first 2 are on my TBR. You don't have to read the previous books to understand this one but it helps with the other characters. I cannot wait for the next one in the series.

[De Smith · Rating 5 out of 5]

This book had me so feral for it from the very beginning. I was fully hooked on this story from start to finish. Sadie and miles were amazing together. I couldn’t get enough. Miles is so obsessive and protective. And I was absolutely here for it. Sadie is so sweet and loving. These two shouldn’t work at all but they do so perfectly. Their connection and chemistry were intense and utterly insane. And the heated moments between them are hot enough to melt a volcano. But this book was more than just these two. The overarching story had me so invested too. I was on the edge of my seat all while blushing so hard it hurt. Especially towards the very end. I was having palpitations and nervous twitching. And I adored every second. I wouldn’t change a single thing.

I finished reading this book in one day! Once I began Sadie and Miles' story, I couldn't stop.
I felt like we almost got two different stories inside one.
I loved how Sadie and Miles relationship evolved. Both were a little shy, but behind the screen they are little bolder.
Then we have the side story of what Miles is investigating. Of course, the author does a brilliant job of tying both together.

This book had secrets, a bit of drama, emotional moments, and spice. We also got a bit of danger and action in the end.
All in all, this was a fantastic read!
I look forward tp Mason's story!

Ruby Wolff did it again!!😮‍💨🔥

Hidden is Book 4 of the Crawford Brothers. This is a dark romance! This series is absolutely binge worthy! These Crawford men are downright drool worthy 🤤😍 Miles(MMC) my god!! That man is really really morally grey and the way the dynamics work with Sadie(FMC) just draws you in from start! Miles is a hacker and he becomes obsessed with Sadie, who is a gymnast. HOLY MACARONI!! The ride I went with these two…FIRE!!! This is a hell yes for me for this book! ⭐️⭐️⭐️⭐️⭐️

[readersinthedark_ · Rating 4 out of 5]

I love how obsessed Miles is with Sadie. Stalks, hacks and everything becomes my love language. Need this type of love because WHAT IS RED FLAGS? LOL. Sadie is Mile's "the one". He takes care of her and he never stops! True love! Something happened that I do not want to spoil it and this really shows the determination of their true loves. I love the setting of the book and the characters. Ruby Wolff's writing is addicting that will want you to keep flipping the pages and find out what happened. Love the plots, the characters and their chemistry and the side characters. Amazing!

[Victoria Wyatt · Rating 5 out of 5]

Ruby did a great job with this one. The suspense, intensity and obsession not to mention the secrets. Miles and Sadie relationship really developed into something special as the story progresses. The way she became a part of his world and protectiveness that came with that. Especially when towards the end. The examination scene was heart warming. The found family she became a part of unexpectedly. The story was intriguing and addictive.

[Linda · Rating 5 out of 5]

Wowza!

I certainly would want Miles in my corner!
Yeah, I know…keeping his eyes on Sadie…without her knowing!
Well!

Dark romance.
Morally gray MMC!
Obsession.
Protection.
Masked man.

What's not to love!?

Ms. Wolff kept me captivated for several hours.
I'm betting she'll keep you totally occupied too!

If you haven't started...you should!
This is FIVE definite stars!

[Tina LeJeune · Rating 4 out of 5]

Miles and Sadie had me hooked! Miles is brilliant, obsessive, protective, and just the right amount of unhinged. I loved the whole Ghost/masked stalker element and watching their relationship unfold while the darker family-business storyline built around them.

The last part had me STRESSED and completely glued to the page. Dark, suspenseful, sexy, and addictive—I’m definitely ready for Mason’s book!

[Steph · Rating 5 out of 5]

Wow...just wow. I wasn't sure how Ruby was going to write Miles' story, but it was so much better than I imagined! It has the perfect amount of darkness and light, spiciness and cute.
Sadie was such a strong FMC. There was never a moment where she was whiny or annoying or gave up fighting. Miles is a strong MMC that protects and loves Sadie with everything he has. My favorite Crawford brother was Declan but Miles may have just taken that spot. Can't wait for Mason's book!

[Elesha's book fun gossip · Rating 5 out of 5]

I love this series and this book was definitely different from the others. It had to duelling side to the MMC which was captivating. Miles is quiet but stealthy in his way. And ghost is his crazy side come out to play (stalking). I loved that Sadie took the crazy in her stride and want something for herself. This was not your typical love story, with emotional pain, danger, and high intensity action. It was a page turner in all the right ways. That I was on the edge of my seat at parts. Highly recommend read
