Mastered #3

Over The Line

Rate this book
Book Three in the Mastered series. He can't say he wasn't warned... From the moment he's cautioned to avoid the submissive who snares his attention, Dom Michael Dayton is intrigued. With her tight dress, flowing hair and honest dialogue, what could be more perfect than a few hours together? Sydney Wallace fears only one thing-being tied down. She lives for adventure and fun, including the occasional BDSM party. By always scening with different Doms, she avoids emotional entanglements that might complicate her life. A man who owns a ranch and has roots deep into the soil is definitely not the kind of Dom she wants to play with. Sydney has never met anyone as complex as Master Michael Dayton. From the moment he issues his first command, she knows he's different. He watches her reactions, sees what she wants, and unselfishly gives her what she needs. Getting involved with a man like him would be the biggest risk of her life, crossing over all of lines she's drawn to protect her way of life. After the first night together, Michael realises he should have heeded the warning. But it may already be too late...

Book 3 of the Master Series and Sierra Cartwright is my new favorite author.

This book doesn't waste anytime jumping into scene play! WOW! And some very hot scenes throughout the entire book.

I would have liked to have seen just a bit more character building in the beginning; a chance to get to know Master Michael and Syndey a bit better first, but Ms. Cartwright makes up for that in, and throughout, the book.

This entire series has captivated me, I love it, and I'm looking forward to the next book in August!

I highly recommend this entire series if this is a genre you're interested in.

Oh yeah, I really liked Master Michael. He knows what he wants and expects submission but likes a strong independent woman and still expects her to be her own person and to have her dreams fulfilled too...A perfect Dom!

The third book of Sierra Cartwright's series Mastered did not disappoint. Master Michael knew what he wanted and no one could deter him. He had been warned that Sydney was not a committed submissive. But Michael didn't care....Sydney intrigued him as well as turned him on. Sydney loved her kinky sex but she had great difficulty giving up her independence to be submissive with any Dom. Their relationship is frustrating and fulfilling at the same time. This story is fun, sexy, hot, and satisfying. Sierra is a talented and awesome author. She makes the reader want to partner with her very own Dom. I loved this book.

Net als deel 1 en 2 heb ik ook deel 3 weer beluisterd als luisterboek en ik word nog steeds vermaakt door de stem van Leo Barnabas. Per boek leeft hij steeds meer mee en ik ben nu best benieuwd wat hij naast het boeken inspreken allemaal doet. (Hij moet ergens zijn inspiratie vandaan halen?)

This is one of my favorite BDSM authors, and this book doesn't disappoint. It's a relatively short read but packed full of action. You get glimpses of each characters emotional back story, but not a lot. Non stop BDSM scenes, I wished there was more of the emotional view point during those, but other than that, great scenes. I've read all of this series & am looking forward to the next book, due in August.

Sydney is a manipulative brat. She thrives on her freedom, no strings attached sex and BDSM play. She's been burned in a relationship and wants no part of another one. Master Michael gets Sydney like no other Dom ever has. He plays her like a fine violin. He too has been burned in arelationship ans is definitely not looking for another. He just wants Sydney's submission and she is not giving it willingly.

Brilliant!

Sierra Cartwright's name on the front is enough to sell it to me anyway. Definitely not disappointed. The 'Mastered' series is just hot, and I loved this latest offering, Sierra at her butt-clenching best. Imaginative, creative, plenty of 'ouch!' and I can't wait for the next one

Another amazing book from Mastered Series now is a story about Sydney a sub who promised herself to not have anymore an exclusive Dom, after the really bad experience she had with an egotistical Dom she decided to not scene with the same Dom more than one time and be free. The experient Dom Michael Dayton also had a bad experience with his ex wife and almost lost his ranch, when those 02 meet sparks fly and their scene is something none of them had before, Michael realizes one scene and one night were not enough. Loved it.

Michael and Sydney have both experienced betrayal in past relationships and as a result are guarded when they scene. She likes her freedom and when Michael gets a taste of her he is determined to get her to commit to him. This BDSM story has intriguing twists and turns that kept me glued to the pages from start to finish.

If you like the bdsm trope, you will love this book. It’s all about it from start to finish. Sidney and Michael are perfect for each other. They had an instant, consuming dom/sub connection immediately. The story was tastefully done and well written. Chewie added a bit of humor to the intense story. What a delightful little character! This is an amazing, erotic romance and it was thoroughly enjoyable. *this was a complimentary copy and this is my honest review*

It was entertaining, I really loved Master Michael.

"I want to give you what you need, not what you want."

"- I don't snuggle.
+ Didn't. You didn't snuggle, now you do."

"- You don't ask for much.
+ Everything you have to give."

"He could wield a flogger and a spatula. Could anything be better?"

When Michael looks at Sydney and is told, 'She's trouble,' he knows it's time to play. What neither of them understand or want is relationship mixed in with some delicious BDSM. It's time to indulge yourself and enter their world in this 10-year anniversary edition. Like the heading says, second chances are the best.

Book 3
Master Michael is trying to avoid entanglements but after meeting the very strong minded, independent and lushest Sydney all bets are off.
I absolutely love when a Dom wants a willing sub but still have a strong independent character.
Sierra Cartwright writes the best BDSM and would definitely recommend this and all her other books.

Michael is a dominant but also wants a woman that is strong and has dreams of her own. Sydney does scenes with one sir and done. He will fight for her and make a life with her. I really loved how determined Michael was to win Sydney over and was not going to stop.

This is quite a good BDSM romance between Master Michael and Sydney. The sex is hot and frequent, the kink is very, very hot.

The goat is great.

The best part is the (with the ups and downs expected in the genre) path towards the compromises needed to make an actual relationship work. Since both characters are rather set in their ways, the path was, indeed, not an easy one.

Hot little Subbie

I loved how Master Michael just oozed dominance and knew everything she needed and how to push her beyond her comfort zone especially when it came to love and submission.
A love story with tons of heat!!!

BDSM done well

When Dom Michael sees Sub Sydney at a scene party, he's instantly attracted. Despite the warnings of several of his friends he has to have her. And not just for a night. Forever.

I enjoyed the other two books in this series, but I didn't like this one as much. Maybe it was I couldn't connect with the characters as much, but I was as in love with this book as much as the others.

That doesn't mean that the book wasn't good, it was, the sex is hot as always and again I like that the author is very honest about what BDSM is and isn't.

But because I didn't love the book or the characters I can only give this

Four stars.

Over The Line is the love story of Master Michael and Sydney who is determined to not belong to anyone. These two have incredible chemistry as well as tension, thanks to Sydney's need to not fully submit to Michael. I enjoyed their book immensely. Hot, hot, hot read!!

Everyone of the books in this series so far has had the same plot outline. Yea the characters names are different but the story is the exact same. I guess if you find a story that works just keep writing it over and over again.

There really wasn’t anything wrong with this book; it was just like book one (I gave 4 stars) and book two (I gave 4 stars) since this one is almost exactly the same, the author had no creativity I gave it three stars.
