Rebel A Stepbrother Romance

I married my stepbrother. No one is more surprised than me. All I wanted was a quiet summer before starting college to catch up on my books and maybe get a summer job. Then he dropped into my life. His name is Gavin Caldwell and he's rich, cocky, arrogant and hot. He's parading around our bridal suite shirtless and pantless. He has no shame and I have to pretend to be in love with him when I hate him. So why can't I stop thinking about him?
