Dangerous Devotion

The Crimson Brotherhood Series Book 1

About

Riley Thompson’s biggest problem used to be keeping O’Malley’s bar running while hiding her creative accounting from the IRS. But when four devastatingly attractive—and lethally dangerous—men make her an offer she literally can’t refuse, her life takes a turn straight into “what the hell am I doing?” territory.

Roman, Sebastian, Miles, and Kieran aren’t just the city’s most powerful crime lords—they’re the Crimson Brotherhood, and they’ve decided Riley’s particular talents make her the perfect addition to their organization. Between knife-fighting lessons that definitely aren’t OSHA-approved and trying to keep her growing feelings for more than one of the men under control (Spoiler alert: she fails spectacularly at that last part), Riley discovers her mysterious past might be exactly what painted a target on her back.

Now she’s juggling late-night distractions, crack-of-dawn workouts that feel suspiciously like torture, and a rival crime boss who thinks she’s the key to his empire. As if that wasn’t complicated enough, her heart seems determined to collect dangerous men like some people collect stamps.

When violence erupts and secrets start spilling like cheap beer, Riley must decide if she’s ready to embrace both the darkness and the light buried within her. Because in this game of shadows and steel, love might be the deadliest weapon of all. Sometimes the family you choose comes with throwing knives and questionable morals. And sometimes that is exactly the family you need.

Praise for this book

Dangerous Devotion is a story about a woman who forged her way as an orphan without her memories. She’s a bartender for her chosen family at their pub and has regulars she considers her close friends. Her boss is having a hard time paying for things while also funding his wife’s medical bills after a cancer diagnosis. So the bartender, Riley, has been cooking the books a bit to make ends meet and this attracts the attention of local illegal enterprise, the Crimson Brotherhood. The Crimson Brotherhood is made up of four found-brothers, Sebastian, Kieran, Miles and Roman. Each brother is hot, smart, strong. Will these brothers be the key to unlocking Riley’s hidden past and help her discover who she truly is?

Holy cannoli, I’m seriously in awe. I’m going to be honest, I was not eager to read this book. I committed a cardinal sin, I judged a book by its cover! Who does that!? I decided to give it a chance because the author was advertising the book, I love a why choose and I love a mafia story. My word am I impressed. Riley is such a carefully constructed character. She’s has real emotions. She’s not a manic pixie dream girl, she a truly relatable girl; well as much as you can relate to amnesiac-bartenders turned… well let’s not spoil it. But beyond that each of the brothers are truly unique. They all have wonderful and different qualities, with wonderful backgrounds. I’m now eager to read the next when she finishes it. I’m dying to know more about Miles. I’m desperate to learn more about Roman. Oh Roman 🥵. I’m hopeful about Kieran but most of all I’m dying to see things develop between Sebastian and Riley. This book ends on a cliffhanger, but it’s worth it. I will be on the lookout for the next book.

Dangerous Devotion by Sloane Castle~
♥️♥️♥️♥️♥️♥️💪🏼♥️♥️♥️♥️♥️♥️
In finding a new author, I found a book that was so riveting so positively sensual yet, volatile, I had to take breaks, and breathe, and then grab my Kindle to continue. That Sloan Castle has built a world where every detail of each character is mapped out so beautifully and cogently you feel as if you are in the room with them is enthralling. Her writing tight, cogent, and ethereal in so many ways. That every érötic scene is blessed with laughter, passion, and love seems impossible—yet it works so well that you wish you could be Riley in every way. Don’t get me wrong: from bartender waif to a goddess amongst vigilantes, Riley is perhaps every woman’s SHERO action figure. But I’ll stop there. You HAVE to read this brilliant book to feel all the feels!

Every man in this Crimson Brotherhood is unique in his own right: From the controlling and sensual Roman, to the lethal Viking that’s Kieran, to the OCD, and untrusting iceman, Sebastian, and the quiet, temperate book-loving Miles, you will feel envious that Riley gets to embrace each of their bodies, souls, hearts, and minds.

Castle has a gift. Her writing draws you in so easily time slips away! Her ability to insert classic books, quotes, into love making is an art form; her understanding of a man’s psyche is masterful; and her desire to show the strength women possess, powerful.

I am on pins and needles waiting for the next installment. Do yourself a favor and get this book immediately. You will not be disappointed!

Chills the ending left me with chills. I just gotta know how long is the wait for the next book? Wow I started this book yesterday and I could not put it down. The chemistry between Riley and each of the male main characters just explosive. She is truly the other half of each of them. This book was well written once the next one comes out I will be rereading this book again.

This story is captivating! The characters are so well written and their stories pour out so beautifully page after page. I'm chomping at the bit for the sequel! I'm not a fan of cliffhangers, but this one is so worth it! I think I have a new favorite author!!

Wow.. what a book! Just like the wolves.. I fell, and i fell deep! From the internal thoughts that we are privy to (strangely comforting that I have similar ones.. and similar sass) to the way Sloane describes just enough to keep you guessing but the perfect amount to get you hooked! Collectively, I spent about 3 days absolutely obsessed with this story! Between being a busy mum and doing the mundane tasks, my thoughts often drifted to what I'd read so far, what i expected to happen and expecting the unexpected.. let me tell you- my fragile little mind was blown by the end of this! I can not wait for the next installment of Riley, Kieran, Sebastian, Roman and... Miles' torturous masterpiece! I guess like those wolves of Rileys... I'll just have to wait and see!

Gripping, feisty, dark, sexy and utterly utterly wiked! Just a few carefully chosen words to exude this big book energy! What are you waiting for? Read the thing! You won't be disappointed!😉🫡
