Tanner Steele:

Sometimes I feel like my story is written in the lyrics of those sad, old country songs my mother used to sing to me on her "good" days. The boy from the wrong side of the tracks. A beat-up truck on the road to nowhere.
Fate intervened in the form of my best friend and his family.
The Whitlocks lived in a big house up on the hill that looked like a castle. I spent every minute I could there.
And, just like a real castle, there was a princess.

Sterling Whitlock, the girl I should have loved like a little sister. I thought I did. Until she turned eighteen, and looked at me with shining eyes, congratulating me on Kingmaker getting our first recording deal.
I was lost.

But she's my best friend's sister. The daughter of the people I owed my life to. So, I swore I'd never touch her. Never stain her perfect skin with whatever dirt I couldn't shake off when I left my old neighborhood. But on the night of her eighteenth birthday, I slipped and since then, I've stayed away.

I'm the lead singer of the biggest rock band in the world. Her brother doesn't know it, but every song I've ever written has been for her.
And now she's coming on tour with us.
Her mama's asked me to watch over her, but I don't think she meant it the way I do.
Obsessively.
I'm on a razor's edge and Sterling keeps pushing my control to its very limits.
