The Final Fury: Shadow Sisters Book Three

Rate this book
A trail of victims. One terrifying madman. And the echoes of an evil that took everything.

On a forgotten farm in Buffalo, Wyoming, the body of a young woman is found slumped over a pig trough, her throat slit, an unfamiliar symbol burned into her forehead.
Nearby, a set of rosary beads dangled from a fencepost—the signature calling card of a vicious serial killer known only as 'the Apostle'.
His mission is simple—to claim his seat at the table of God. But to prove his worth, he must first offer seven sacrifices.
Seven sinners, seven deadly sins, seven consequences.
The Apostle is on the hunt for the wicked among us. And he's just getting started.

Two sisters faced down a killer. Only one made it out alive.

Haunted by the ghosts of the past and ravaged by scars that refuse to heal, one woman must learn to trust her psychic abilities to stop a serial killer before he strikes again.
But it won't be easy. Because the Apostle is evolving, meticulously preparing for his greatest role yet.
The role of a lifetime.
He isn't killing for the Messiah, he's killing to become Him.

BRAVO BRAVO!!! Quinn Noll has just released the EPIC conclusion to her Shadow Sisters Trilogy! This is the final installment and must be read after Book 1 - Apostle’s Fury and Book 2 - Disciple’s Fury.

In this story the villain we’ve all learned to hate so hard is at it again! This time he’s ticking off the seven deadly sins in order to achieve absolution and become the Messiah. I really can’t say too much because I don’t want to give away ANY spoilers but this is an absolute must read!!!

If you’re reading this and haven’t heard of book 1 or book 2, let me run it down for you quick:

Book 1 - Katie Callahan is a professor and anthropologist who is an extreme empath and clairvoyant. She also volunteers her time and talents with her cadaver dog, searching the mountainside for human remains. She’s helping the FBI when she meets the dreamy agent Jake Deauvereaux. Together they realize there’s a serial killer targeting everyone Katie loves and adores. It’s a race to stop this maniac before more people find themselves tortured and dumped.

Book 2 - Ms. Callahan picks up and moves to Wyoming where more bodies turn up. The Apostle has found a partner, the “Disciple.” Investigators, police and friends team up with the Callahan family to answer the question if these new bodies are related to the Apostle murders or could it be a copy cat? They collect clues and uncover secrets along the way. There’s murder and secrets and confessions OH MY!

This trilogy is an absolute must read. Easy 5 stars from me!!! If you love mystery, thriller, romance - this book has it all and so much more I don’t want to say. This is a SPOILER FREE REVIEW and my honest opinion of Final Fury by Quinn Noll.

Good golly Quinn!! Spent my whole day reading with a few work interruptions here and there. My heart was ripped out and shattered with book 1, my eyes couldn't read fast enough with book 2 and the insanity in book 3 had my heart rate elevated.. Every single one of these novels you could envision page after page, scene after scene. The descriptions, charismatic characters, the laughter and verbage, witty comments and jokes, Quinn did her research for this trilogy and personally I feel her hard work paid off. I will recommend and gift this trilogy whenever I can! Thank you so much Quinn for this amazing trilogy that has your heart pounding edge of your seat gripping page turner.

I have loved this trilogy SO much! This book had me on the edge of my seat from the very beginning! Gabriel is even more twisted in this one which I didn't think was possible. 😁 I both couldn't wait to see how it all ends but also didn't want it to end!
I can't wait to see what Quinn Noll writes next!

i took way longer this time to finish this book, only because i was nervous of how it was all going to end. or scared if there would be loose ends that would irritate me but it actually all tied together VERY nicely !
i will miss the characters and wonder if we might revisit them in a spin off later on? 🤭😉
either way this book and series as a whole was awesome! so glad i took a chance and read something a little different from my norm. it was well worth it






**i hated simon so much but the wood chipper though?! 😂oooof.

Great conclusion to the series

Quinn Bill does it again. This was another great book and wrapped up the series quite nicely. I'm kinda sad that there may not be any more Shadow Sisters books. I throughly enjoyed this series.

The Final Fury is the third installment of the Shadow Sisters series following the Callaghan/Deveroux families and their hunt for the serial killer known as the Apostle. This is a dark psychological, paranormal, crime thriller with a romantic subplot. Some content/trigger warnings include depictions of violence, religious fanaticism, and gore.

4.5/5 - Quinn Noll knows how to write psychological. I really enjoyed the way the escalation and delusions of the Apostle was depicted. This book was a great close to several mysteries in the previous books that we get answers to in this one. Quinn Noll is great at planting red herrings and making you think one thing while finding out its not what you expect. As with the last books, I also greatly enjoyed the biblical references and personally find stories about the seven deadly sins to always be super interesting.

My review of The Final Fury by Quinn Noll. (I am not being compensated for this review).

This book series was one of the best I've read. Every character had their own moment, their own dynamics, and made me feel like each one was important in their own right. I felt that reading this book would be bittersweet since it was the final one in a series. I was right. But it was so worth it. The character arcs were completed perfectly. I didn't feel like anything was missing at all. I loved the relationship between Callie and Jake and seeing it develop throughout the pages. I'm not a fan of books that drag background scenes out unnecessarily, and luckily, this book doesn't do that. Background info stays in the background. I also do not believe in God, and as such, I don't like to read books with religious themes, however, the religious aspects of this book are integrated in a way that makes it entertaining without being preachy. The religious parts are used very well and only add to the good of the story. All in all, this was a very great read and perfect end to the series. I'll miss reading about these characters, but I look forward to the future books by this author.

Book 3 is as good as Books 1 & 2. Great read if you like fiction which I do. All 3 books had great storylines and some romance. I liked that the romance was there but it wasn’t the main part of the storyline. Kept my interest thru all 3 books. The only disappointment for me was the inaccuracy of the Bible related information. Quinn Noll has caught my interest as an Author and I cannot wait to read more from her.

I have read a lot of series in my life and very few can keep the tempo or in this case get better as they go. I am sad this is the last one. Some of the things that happen in this book are pure genius. There is nothing not to like about this book or the entire series. It's fast paced, great characters and character development and the ending was perfect!

Good Story

These books are very interesting. The characters are well developed and interesting,, as well. Several mysteries are intertwined throughout the books.
You do need to read them in order. The one thing I did not care for was the character of Katie dying in the first book. I would have enjoyed it better had the other twin died.
However, you will enjoy these books. Keep in mind, there are supernatural elements throughout.

Loved It!!

I just finished this 3rd book of The Shadow Sisters Series and it was as good as I figured it would be! Plenty of twists and turns, diabolical plots, and plenty of humor and love in between! I highly recommend any book this author writes!
