DESTROYER: The Santini Assassins, Book Three

by Stoni Alexander

THEODORE SANTINI
They call me the boogeyman for a reason.

I operate in the shadows, eliminate threats before they surface, and do the kind of work no one can afford to acknowledge. As a Santini, power runs in my blood. But I wield it quietly, lethally, and without mercy.

Family comes first. Always.

Love?
That was never part of the equation.
Until she comes back.

She’s brilliant, fearless, and every bit as dangerous as the BLACK OPS world we move through. She doesn’t need saving. She’s a badass, a deadly weapon in her own right. From the moment she steps back into my life, I’m compromised in ways no enemy has ever managed.

Our chemistry is explosive.
Our history is unfinished.
But the timing couldn’t be worse.

As I take command of ALPHA’s most critical mission yet, a global terror cell sets its sights on my team… and on her. Every instinct tells me to lock her away somewhere safe. Every truth I know says she belongs by my side.

This mission demands sacrifice.
Because if I fail, innocent lives will be lost.
And if I succeed, I may lose the one woman who finally makes the darkness bearable.

I don’t make empty threats.
If I say I’m coming for you, I am.
And when I find you, there will be no way to stop me.

Whew! Is it hot in here or just me? This story had it all! Suspense, murder, bad guys, chemistry and an all-around great read! I was very quickly sucked in to Teddy’s story. Sydney gave him a run for his money. They made a good match and the chemistry between them was palpable. I couldn’t read this book fast enough! I enjoyed how part of this story line continued through all three books in this series. Make sure you don’t let this book pass you by!

Stoni writes books that a highly suspenseful, spicy and very complex - a winning combination for me!

I love how she always surprises me with a twist or direction where I’m always left wondering if what I’m sensing is where she’s taking the story, sometimes I’m right and sometimes I’m blindsided with a jaw dropping plot twist. I love the extra suspense and intensity it brings to reading her book.

From start to finish this book held my attention and had me addicted in wondering what’s next.

Both Teddy and Sydney were intriguing secondary characters in the previous book as their siblings fell in love with each other it was obvious sparks were igniting between these two. These two are perfect for each other and able to seamlessly work closely together professionally while they are also exploring an intense physical connection. Teddy is calmed by Sydney’s presence and she feels seen and supported by him. Loved these together.

There is so much story to enjoy and it will keep you glued to the page or your screen. Stoni is an author that is not just a ‘one-click’ for me, but she’s a make sure I clear my schedule so I can dive right in and not be interrupted while I live vicariously in her amazing world. Her books are a guaranteed 5+ star reading experience for me.

I received a free ARC from the author; and I am voluntarily leaving an unbiased review.

Destroyer is the perfect ending for The Santini Assassins series (although I am sorry it's the last.) Two assassins, each with their own assignments/agendas team up to deliver the ultimate endings for their targets. To Teddy "Tank" Santini, Sydney Austin was the one that "got away." He was enthralled from their first meeting. As was she but he had no idea. Finding her again, he vows not to let her slip away again. Together they burn hotter than an erupting volvano. Both at work and in the bedroom. Joining the Black OPS team temporarily allows her to show her invaluable shooting prowess to the team. The Day of Destruction mission ramps up to an international level and surprisingly dovetails into her old assignment. Ms Alexander knows how to ramp up the suspense, intrigue, danger, drama and spice into a tale that captures and holds your interest and attention from page one. I'm looking forward to the next series she hints at ind Destroyer's final pages.

In the third and final installment of the Day of Destruction series, Stoni Alexander is her usual self: Brilliant! She is an accomplished author who creates her own stories and does not rely on AI to do it for her. Letting her imagination soar results in the best books. This one is no exception.

The characters of Tank aka Teddy Santini and Sydney Austin are two sides of the same coin. Both are charming, justice driven, hot, sensual personalities. And hired assassins.

If you have read other Stoni Alexander books, you will be familiar with the secondary characters that appear in Destroyer. Comrades who have each other’s backs.

Stoni’s books are well constructed, with intricate twists and turns, and hot, hot, hot sensuality.

Read this book! And you will become a dedicated fan like I am!

A highly intense wild ride
Destroyer (Santini Assassins Book 3) by Stoni Alexander is one of those books you just don’t want to put down. Teddy is the hero made of dreams and Sydney is his perfect match.
The intrigue is intense as Teddy, Sydney, and the super secret group maneuver through clues and running down leads. While the danger is high, their skills see them to success.
I truly adore Teddy and Sydney together. I felt bad for Sydney’s loss, but Teddy was there for her so perfectly. While I started falling for Teddy in the first book, he really stole my heart in this book.
Overall, Destroyer destroyed the villains with Sydney’s help and I absolutely recommend this rip-roaring ride and love story to HEA.
I read an ARC of this book and voluntarily share my review.

Factory Reset Please

Is it me? This didn’t flow like the others or maybe it did and I forgot somehow.

It was flat almost. Yes it had some “action” but the story fell flat. Most of the book seemed to be the I love you’s (too damn fast), the comfort and “relations”; I just wanted it to be over.

Next book is Gabriel and he’ll likely fall in love with a rivals daughter which is the trouble he brought to the dinner. I’m almost deterred from reading it but I need to see this to the end.

Wow! A-M-A-Z-I-N-G! Destroyer is an action packed thriller from start to finish. Tank and Sydney have a chemistry that could start a fire. Tank and Sydney are a true power couple in more ways than one. Once you pick this book up, you won't be able to set it down until it is finished. If they are not going after the terrorists, they are going after traffickers. There is so much action going on in this exciting story. There are so many twists and turns, you can't see them coming. Stoni Alexander never disappoints!

Perfect Pair

Sydney is amazing. Everything she can do and who she is as a person. Loved her character. She wasn't going to let anything stop her on her mission.
Teddy is someone who knows what he wants and he's going to do everything he possibly can to make sure he achieves it.
The two of them together are unstoppable. They push each other to be better.
I have loved the Santini's and cannot wait for Gabriel!

Another great book in The Santini Assassins!

What a fantastic read The Destroyer was, Teddy and Sydneys love story was filled with action and passion yet quite a few twists and turns. I loved every page in this book and highly recommend it !❤️🔥

[Elayne Mayes]

Loved this series!

I am biased since I am Italian, a Navy family, and think these brothers are so handsome. Sydney is the coolest bad ass! Love her. Looking forward to Gabriel’s story.

[Diana Lepine]

Wow! What a great story. Mystery, intrigue, and love all rolled into one book. The characters are admirably written, tough but human with guilt feelings. They can live with it because what they do is for the greater good. Masterful writing by the author. This is a must read series! No regrets!
