This three-book bundle is a spinoff from the uber-popular K19 Security Solutions Teams One and Two series and takes listeners into the darker depths of security and espionage.

K19 Allied Intelligence, a covert paramilitary operations unit, is the world’s most secretive, deadly, and lowest profile special ops organization. When innocent lives are threatened, this team has the strength and intelligence to save them. As the K19 Allied Intelligence Team One agents gear up for counterattacks, the war on trafficking ignites. Come hell or high water, these agents will take down the enemy one by one.

Introducing the daring and dangerous private intelligence agency, K19 Security Solutions. In this four-book boxed set, these men will battle external enemies and internal passions to protect each other—and the women they love.

When security and intelligence is threatened, the partners of the Invincible Intelligence and Security Group come to the rescue. They save lives. They challenge each other. And they protect the strong women they fall for. The men and women of the Invincibles get the job done.

To the public, they’re winemakers—each a billionaire in his own right. However, there’s far more to these men than meets the eye. Their membership in the secret society known as Los Caballeros has been handed down to them from their fathers and grandfathers for generations. Their vow? To come to the aid of the innocent and less fortunate, offering protection and safety, even when it means putting their own lives on the line.

Owen Cullen was a dream. Not a dream come true though, because I’d never dared to dream. He was my wildest fantasy, a hallucination, a delusion. The handsome man who’d saved my life—twice. He was a real-life hero, and I was...what was I? Filth, that was what I was.

For Tate Vickers, becoming a GHOST operative was inevitable. Being raised by GHOST operatives, he and his coworkers played rescue games as children. When he’s tasked to run the elite group’s satellite location in Kentucky, he jumps at the chance and brings his friends along. But Glen Hollow, Kentucky isn’t what it seems. There’s a dark secret living in the hills and a war is about to erupt.

Will this growly protector break her book-loving heart...or become her second chance at love? Savanna Vasquez lost her Navy SEAL husband years ago to terrorists, and she doesn’t think she’s capable of falling in love again. Then came Griffin. The inexplicable connection between them has them both wondering if maybe they were brought together for another reason. And as Griffin does everything in his power to save Savanna, he discovers there’s a chance she just might save him, too.

I've been dreading this for a year. Okay, that's a lie. I've been dreading this reunion since we graduated high school 10 years ago. So why am I here, standing outside the door like the eternal wallflower I am? I'd say it's because my younger sister browbeat me into it, but the truth is, I'm tired of being a nobody. Of never taking a risk with myself and my life. And...well...maybe I'm also hoping to see him. The tall, insanely gorgeous man walking my way now. Oliver Fritz is regarded as one of Boston's sexiest doctors. I know him as the former god of our school.

Museum curator Haven McKinney has sworn off men. All of them. Totally. She’s recently escaped a bad ex and started a new life for herself in San Francisco. She loves her job at the Hutton Museum, likes her new boss, and has made best friends with his feisty sister. Haven’s also desperately trying not to notice their brother: hotshot investigator Rhys Norcross. And she’s really trying not to notice his muscular body, sexy tattoos, and charming smile.

Brady Hewitt was all too familiar with the horrors of war. They clung to him, or maybe he clung to them, using the nightmares as an excuse to keep others at bay—especially his boss’ daughter, Hadley Walker. Beautiful, sexy, ambitious, and forbidden. Not just because the former Special Forces soldier respected her father and liked his job, she was too good for him—all sunshine and smiles while he was darkness and filth.

Magnus arrives in the Artic for severe-weather training, overseen by an international joint task force, but run by military brass. With multiple countries involved and multiple divisions of the military, it’s a wide-open mix of potential trouble. And trouble is what he’s here to find. Not to create. However, after meeting the one and only doctor on-site, a female member of the British team, Magnus knows that she needs his help to keep her safe. Yet she can’t be his main interest, not when something is seriously wrong at the compound. Too bad his heart wasn’t listening....

 Brooke Sullivan’s carefully ordered existence is spiraling out of control. Two years ago, she was violently abducted by a terrorist group and nearly killed. She’s worked hard to get her life back on track—moving to a new house, changing careers, going on a couple of dates. When she witnesses a murder, she’s plunged into a new nightmare. And as the past threatens to repeat itself, she’s not sure she’ll survive this time.   

The Stealth Ops Series Box Set includes the following three Navy SEAL romantic suspense titles by Brittney Sahin: Finding His Mark (She's crashed the biggest party of her life, and she's about to pay the price), Finding Justice (They say the truth will set you free - if it doesn't bury you first), and Finding the Fight (Their well-kept secrets are about to unravel). 

He’s the billionaire Beast of Calico Cove, and I’m his sacrificial lamb…I mean, his new employee. Malcolm Bettencourt is a recluse with a nasty scar across his face and a bad attitude. He has a bone to pick with my family over a loan my dad can't pay back, so to save our lobster business, I agree to be his live-in housekeeper and cook. We have nothing in common, and there’s no reason to think he would want anything to do with someone like me. Except I can’t stop thinking about him, and he can’t stop looking at me.
