My terribble stepbrother

Description of book "My terribble stepbrother"

"Get out of my bedroom!". The stepbrother is not thinking of leaving.
"There is nothing in this house that belongs to you or your mother, I advise you to remember that!". He does not hide his contempt for me.
"Our parents are married..."
"I will fix it soon", instead of a smile on his lips now a predatory grin. He no longer intends to keep our secret.
"Do not do it..."
"It will cost you dearly..."
"What do you want for silence?"
"Soon you will find out", his smile makes me feel cold. Nothing good is waiting for me.
