Only the Devil

Pretending to be her boyfriend was supposed to be simple.

Then I watched her walk straight into danger—and realized I couldn’t stop caring.

The assignment seemed straightforward: pose as a dutiful boyfriend while she infiltrates a finance mogul’s operation. Keep her safe. Keep my distance. Get the evidence and get out.

Simple, until the mogul hired me as his personal security.

Now I have a front-row seat to his empire of greed—and his predatory interest in the brilliant woman I'm supposed to be pretending to love. Every day I watch him dangle millions in front of her like bait, testing her limits, pushing her boundaries.

The problem? My feelings for Daisy stopped being pretend the moment she treated me like I was more than just another soldier following orders.

She thinks she can handle Sterling's world. She thinks she can resist the temptation of life-changing money. But I don’t trust wealth and power. And when bodies start dropping and cryptocurrency millions vanish overnight, I realize we're not just hunting a white-collar criminal.

We're trapped in his web.

Daisy's got secrets she won't share and a past that makes her desperate enough to risk everything for justice. Sterling's got enough money to buy loyalty, silence, and alibis. And me? I've got a heart condition that ended my military career and feelings for a woman who might be playing a deeper game than either of us signed up for.

Only the Devil is the second standalone novel in the explosive Sinful State series, where wealth, power, and desire collide in the shadows. Return to the world of the elite KOAN Security Group in this romantic suspense thriller that proves not all fortunes are made in heaven.
