Secrets and Lies by Rebecca Norinne

Blood is thicker than desire … or is it?
As the enforcer for my family’s crime syndicate, I’m no stranger to revenge.
Until the only woman I’ve ever loved becomes my twin brother’s next target.
He’s made himself clear: either I kill the daughter of our greatest rival or he kills me.
And since this isn’t the way my story ends, I know what I have to do.
So long brother.
