Ruthless Obsession: RBMC

Rate this book
I'm Mavis Ruthless Marticon, a lethal enforcer for the Royal Bastards MC Chicago chapter.

If you cross my brothers, you'll never see another sunrise on these unforgiving streets. While tracking down the latest asshole who dared to cross us, I stumble upon an unexpected a woman who greets me in a way no woman ever has, with her fist. Feisty Sophie is nothing like I anticipated.

Instead of cowering, she challenges me at every turn fiery, stubborn, and utterly unafraid of the rough biker who's taken her captive. I meant to use her as leverage while I hunted down the weasel who betrayed her, but fate had other plans. Now, she's not just a tool; she's a dangerous temptation. I’m supposed to be focused on vengeance, but every moment with Sophie chips away at my cold, hardened heart. I want to shatter her innocence, claim her completely, even as I try to ignore the burgeoning desire that defies everything I stand for. I'm not a man who falls in love. I'm the one who breaks hearts.

But as our paths dangerously intertwine, I find myself not fighting the urge to let her go.

I'll risk it all.

Magnificent

This story is really very enjoyable. The couple is compelling and very loveable. Ruthless aka Mavis is a CEO of the company he is absolutely sexy and good-looking. Sophie is a fiesty and independent even in her personal life. Their relationship will have you engage from the beginning. The romance is so captivating with their antics and witty banter. I enjoyed the feel of their chemistry and sizzling hot passion. The characters are awesome and their sexyness just burns up the pages. Sophie is a fighter and funny and is the kind of person you can identify with. I really enjoy this MC vibe it gives you extraordinary experience that I definitely enjoy reading. This couple romantic relationship is delicious and I want to read it more than once. It's a great love affair that makes you smile. I really enjoyed this story so much I didn't want it to end. It's filled with action and vengeance this story was great I would have enjoyed it to be longer but as always good things must come to a end. The story is worth more than five stars to me. Happy Reading

Yess!!!

I know you said that this is a standalone book but I really hope you change your mind .Ruthless was just that and he didn't sly away from it when it can to what he considered his Sophie .It's been a long time since I read a book from cover to end and I did with this .I really wish Toby torture last longer but it didn't that was to good to a end for him .I have to say I really need to get prez back story and meet the woman that tames him.It was good to see past characters show up but I really still do want Hayden and Lydia follow up as well as more Sebastian and Sydney.But as always Posey great job as please give us more MC books

Mavis Ruthless Marticon sees something or someone he wants, and what do you think happens. Yep, that's right, I'm not going to tell you. Sophie thinks she has the perfect boyfriend in Toby. But does she?That is the million dollar question, or maybe it's more. I liked Mavis he really is Ruthless and a bit unhinged, but it was fun to watch him in action. Unfortunately, Sophie got on my nerves a bit at times. I wish we got to see more of Mavis being Ruthless on certain people. You'll understand that when you read the book. This was my first time reading this author, but it won't be the last time.

Ruthless (Mavis) is a top-tier alpha male who is both ruthless, s#$y-as sin, and loving. I adored Ruthless and Sophie's story, which is packed with twists, turns, drama, suspense, and steamy scenes. Don't hesitate to add this book to your e-reader right away. Ms. Posey has outdone herself once again!

Action Pack

Ms. Posey you did it again. You know how I love a strong female character that can hold her own. Sophie and Mavis were perfect for each other. I did want Toby to sit in the torture chair. That man was too much. I would definitely like to read another about Sophie and Mavis.

RBMC Chicago

The title perfectly reflects this story! A fine example of "don't judge a book by its cover" as Ruthless is so much more than the MC! I can't wait to see who's next!
