My Stepbrother, The Billionaire

＂I want you, Kyra. With every fiber of my being. With every breath that I take, I want you. You have bewitched me as no other woman has and I am determined to get over you. To not feel this way. You will not ruin me.＂

MASON:
I had been burned enough times by women to know to not get involved seriously with any of them.
But one look at Kyra, my new stepsister, and all bets were off.
I didn’t want to be attracted to her, but I was.
When my father asked me to keep an eye on her for the summer, I couldn’t say no.
I would just need to fight my attraction to her.
You can imagine how well that will go.

KYRA:
I hadn’t known what it was like to have someone actually hate me.
But Mason did.
Which would be okay with me if he wasn’t so damn sexy.
I tried to be friends with him, and instead, he kisses me.
Rocks my world is more like it.
And I know I will never be the same.

This is a standalone romance with a guaranteed HEA and no cliffhanger or cheating
