—ADMIRAL—
When asked to help with the investigation into the murder of a colleague, I know I’ll have to recuse myself as mounting evidence is discovered that suggests my own cousin is the main suspect. Then, I meet Alice Gordon—brilliant, beautiful, and determined to avenge that colleague’s death, who I learn was her sister. As we uncover a web of corruption that reaches from organized crime to the highest levels of government, I find myself falling for the one woman who couldn’t be less “my type.” With enemies closing in and trust in short supply, we'll have to decide if the truth is worth dying for—and if love can bloom in the shadow of betrayal at the hands of those we believed we were closest to.
—ALICE—
My sister's death was no accident. As a hacker who exposes corporate corruption, I know how to uncover secrets—but nothing prepared me for discovering Sarah's connection to the FBI and the dangerous game she was playing. Now, with help from Agent Pershing Kane, aka Admiral, I'm diving deeper into a conspiracy that threatens everything we hold dear. He's everything I never knew I needed—strong, protective, and willing to break the rules to find justice. But with corrupt agents gunning for us and a criminal empire that wants us silenced, our growing feelings could either be our greatest vulnerability or our salvation.

I dedicated my life to bringing down my brother’s criminal empire, sacrificing everything to expose the corruption that ran through my family name. The last thing I expected was to fall for Lark Gregory—the granddaughter of a woman whose family mine had destroyed generations ago. But from the moment I saw her at that coffee shop, I knew she was different. Now, as threats close in from all sides and long-buried secrets surface, I’ll do whatever it takes to protect her. Even if it means facing my own brother and uncovering truths that could destroy us all.
—LARK—
I was raised on stories of how the Castellanos destroyed my family’s legacy. The last person I should trust is Alessandro Castellano—no matter how much he claims to be different from his criminal family. But as danger circles closer and my grandmother’s closely-guarded secrets begin to unravel, I find myself turning to the one man I was taught to hate. Now, with both our mothers’ disappearances somehow connected and old vendettas threatening to tear us apart, I have to decide if love really can overcome generations of hatred.

She spent her life in hiding, protected by secrets.

an attraction that could destroy them both.

I've spent my career taking down corrupt organizations, but protecting Chiara Castellano is testing every ounce of my control. She might be Alessandro's sister, but she's nothing like the hardened criminals I'm used to dealing with. She's brilliant, beautiful, and determined to help bring down the Belcastro family—even if it means putting herself in danger. My job is to keep her safe, not fantasize about crossing every professional line I've ever drawn. But in the shadows of a Manhattan safe house, with a hit squad closing in, those lines are starting to blur...
—CHIARA—
Everyone thinks they know who I am—the sheltered Castellano sister, raised in hiding, too innocent to understand the dangerous world I was born into. But they're wrong. I know exactly what I want, and right now that's helping Grit investigate the family threatening everything we've built. He thinks he needs to protect me, but I've spent my whole life being protected. What I need is for him to see me as more than just another person to guard. When we end up trapped together, all those careful barriers he's built start to crumble. Now I just have to convince him that some risks are worth taking.
