His Red Carnation by Cassandra Vega

Sloane:
I’m the President’s daughter. He’s my new bodyguard. He’s a man—a real man—and he’s older. Much older. But that only makes me want him more.
From the moment we met, there was an undeniable attraction, something magnetic that pulled us together.
But he sees things differently: I’m young, too off-limits, and the biggest flaw? I’m his best friend’s daughter.
He pushes. And I pull. But I always get what I want, and what I want is him. And I’ll do everything I can to show him I’m worth it.

Callan:
She’s smart, witty, and the most beautiful thing I’ve ever seen. But there’s a problem. Actually, there are several: I’m her bodyguard. I’m supposed to protect her, to keep her safe. Her father, my best friend, trusted me to look after her. I wasn’t supposed to fall for her, but from the first glance, it was out of my control. I’ve fought wars and won, but this was a battle I was destined to lose from the start.
I know exactly what’s at stake, but none of it matters. Because I know she’s worth it.
