Bullied by my Stepbrother

"Kai, please," Jenna tried one last time, grabbing at his arm. "Please don't hurt him. If you want to punish someone, it should be me."
"Foolish girl." Kai laughed. "I AM punishing you."
As he strode off in Jacob's direction, she could only watch helplessly.
Starting at a new school halfway through the year isn't easy, but it's a lot worse when the only person you know is your evil stepbrother. He's sadistically cruel - the worst kind of bully - and he's determined to make Jenna suffer.
When Jenna goes to school with him, she sees him bully a gorgeous guy called Jacob who she immediately has a crush on. In order to stop Kai from bully Jacob she agrees to do what he wants...
She wishes she could stand up to him, the only problem is, she finds herself falling for him despite all his torture.
Can she find a way to melt his cold heart, or will she be crushed by Kai or one of his numerous enemies before she can get the chance?
