The Mastermind is a real page turner

I enjoyed reading this book a lot. Kept my interest could not put it down. If your looking for a new author? Brian O’Sullivan won’t disappoint! I hope they make a movie out of this book. It would be a first class movie.

DNF

Just wasn’t interesting at all

The blured line between mastermind and serial killer.

Mr. O'Sullivan keeps you turning the pages as the narrative changes point of view, as a Jack Reacher sized villan developes a taste for murder and revenge.

I really liked this book. I’ve read most of Brian’s books, and all are good. This one has a great detective and an evil villain. I like how it has the initial story, then branches out to another. I can’t wait until Brian comes out with a new novel.

Great writer

This Is one of those authors that you can't get enough of. I am pissed that I have to wait for him to write a sequel as I AM hanging over the edge of the abyss. Please, Sir, finish the Mastermind!
Every one of Mr. O'Sullivan books are those you cannot put down! What a gifted writer!

OMG...why aren't more people talking about this book? This was a masterful read! One twist after another! This book has it all and I couldn't stop reading it- so much action, fabulous characters, fast-paced, such fun! And a return of Noble Dunn from a previous book - a character that I just loved makes a reappearance as the lead detective trying to solve the string of murders. This book has it all, but be prepared because you won't be able to put it down! Thanks for another fabulous read Brian O'Sullivan!

"The Mastermind" is Brian O'Sullivan's 11th novel, and just like the previous 10, this book was absolutely amazing. "The Mastermind"is a thrill ride that will not allow you to put this book down. One of Brian's other books "The Bartender" was my favorite of all of his books, but "The Mastermind" has now taken the top spot. If you are not familiar with this author, you are missing out. I cannot wait to read his next book.

Just when I think each book by Brian O'Sullivan is my favorite, he does it again! The Mastermind is several stories with in a story that eventually all tie together. The main them is greed and what a person will allow for the big payoff. Sadly it never ends profitable.
This book will definately keep your attention because you never know what may happen next. I will recommend The Mastermind to all my fellow reading friends.

The Mastermind.

This was an amazing read. It kept my attention the entire time, and I'm mad about the cliffhanger at the end. I'm not sure who exactly to give the title of mastermind to because Roger executed everything perfectly in this book, but Brian, the author, had to put it to paper, and it was amazing.

I thoroughly enjoyed this story. It had great characters and lots of intricate plot details. There was no points where the story dragged at all, it moved fast. When I got to the end, my first thought was "it needs a sequel". I hope we get a continuation of the chase at some point in the future. I love this author's books and his writing style.

I love Brian’s twisty stories with multiple narrators, giving you insight on all major characters. What I don’t love is the writing, the typos; it distracts me from the book. Every character’s narration is the same style, every dialogue is forced, to be sure you grasp the goal of the narrative. I’d love to edit a book of Brian’s!

Nice twists

I was surprised by this book. So different from what I’ve read so far. I think I like it the best of all your books. Things kept surprising me all along. Can’t wait for another book!

Tense and Terrifying

Once you've finished this roller coaster of a thriller, you'll find yourself hard pressed to decide who's the bigger mastermind, the killer, or Brian O'Sullivan, for creating a truly evil psychotic who has dubbed HIMSELF "The Mastermind"?

[Mary · Rating 4 out of 5]

O'Sullivan has become a favorite of mine. He really brings all of his characters to life and his stories just flow. I loved how he incorporated elements of The Bartender in this one even though it is a stand alone. I cannot wait to read what happens to Noble next!

[Ashley Dublin · Rating 5 out of 5]

Great quick read!

From the beginning the mastermind was a page turner! 5 murders and the book was only half way through. Was a very quick read and loved that there was a cliff hanger at the end!

[Tara Leighton · Rating 5 out of 5]

Another excellent thriller from Brian O’Sullivan! The back of the book tells you to “be prepared for mayhem”… And mayhem it is! Who can be trusted? Who is lying!? This multi narrative thriller will have you questioning everything!! It’s a five star must read!!

[Lucia Antocci · Rating 3 out of 5]

The writing was ok but I just didn’t love the topic. The story wasn’t one I would typically read, so if you like that kind of story, you might give it more stars. I’m still willing to check out his other books.

[Yvonne Hoover · Rating 4 out of 5]

This is his 4th book I’ve read. Lots of twists right from the start. Just when I thought the book was over there was a part 2 with even more excitement. I did the audiobook on Audible and each character had their own voice which brought the book to life

[Donna Bogan · Rating 5 out of 5]

Great read!

Liked the characters and the twists and turns. Had already read the predecessor book “The Bartender” and this was a good follow-up.

[Raymond Longaray · Rating 5 out of 5]

Excellent and well written very interesting and original. Great characters

[Heather Williams · Rating 4 out of 5]

Not as good as the Bartender but still a fun read.

[Jan Glover · Rating 5 out of 5]

Love the pov ! Each victim tells about their own demise.. surprises at every corner.. and a cliffhanger to keep you mystified..

[Richard Haynes · Rating 5 out of 5]

Well done Brian O'Sullivan. Another 5 star, the hits just keep coming.

[Elizabeth Zak · Rating 5 out of 5]

Another great book by O'Sullivan! One where you truly don't know what will happen until the end! Can't wait to read the rest of his work.

[Anita · Rating 5 out of 5]

My first Brian O' Sullivan book and I really loved it. I loved the short chapters and the multi narrative of the characters. The characters kept me engrossed in the storyline. Highly recommend.

[Jane Dougherty · Rating 5 out of 5]

The Mastermind was such a great book. Wow! I wish there was a sequel. I loved The Bartender and The Photo Album too!!! I'm hooked for sure. They would make fantastic movies.

[Azfa Yazrin · Rating 3 out of 5]

A standalone

[Hilary O'Malley · Rating 5 out of 5]

Another great one

Another great book by Brian O'Sullivan. This book was action packed and quick packed. Hopefully we'll get another follow-up in Roger and Noble.

[Rebecca Dulac · Rating 5 out of 5]

All I can say is WOW!!! I can't even pull all my different thoughts together to calm my brain down! What a doozy! An amazing story with such great twists!

[Sam Kelly · Rating 2 out of 5]

SO MANY POVS just write in third person at that point
