Callie Jensen has led a life that would send most adults running and hiding under their beds. From a young age, she was kidnapped and forced to use her considerable skills for bad. Betrayed by her own family in the worst of ways, she's all but lost hope of being rescued in this cruel world.


Knowing her odds, she does something reckless knowing she probably won't survive much longer anyway--she gathers everything she has and cracks open the case on one of the most dangerous, ruthless criminals in the world. Because if she's going to die, she wants to take Nikolai Ivanov down with her.

Except, a team from a secret government sect throws a wrench in that plan. 

It's a race against the clock to stay one step ahead of a man with unlimited reach and resources--one that now has a very personal vendetta against Callie.

Callie is temporarily with the Cardinals while she tries to figure out what it is that she wants from life. Her childhood was dictated and decided without her, and now she has to learn whom she is as a person without someone telling her what to do. On top of that, her captor is still out there, running free and--if she knows him like she thinks she does--he won't be happy until he has killed her, or worse. It's a good thing that she has so many Delta people looking out for her.

Red Cardinal

Release Date: August 30, 2019


Callie Jensen has always been a little bit different. She was made fun of for being a math-whiz in school up until she was kidnapped. Growing up in the crime world from a young age, she was turned into a language savant and a hacker-expert. 


A secret government organization comes for her. She finally has some allies in the form of several muscular, irresistibly handsome and talented guys. Callie wonders if she'll be able to find peace, but the struggles only keep piling up as she is shuffled around, wondering when or even if she will ever find somewhere she feels is safe.


People whom she thought were safe might not be. And not only that, but her kidnapper is not willing to give her up without a fight, and he shows her all too well that he will go to some very dangerous lengths to get her back.
