Vicious (Sinners of Saint #1) by L.J. Shen

This is a great story of growth, understand, faith, and forgiveness. Vicious was exactly what his nickname implied. He was a vicious and vindictive, he only thought of himself and no one else. Or did he? He told everyone including himself he hated her from the minute they met, but he was so stubborn it took him years to listen to his heart.
Emilia moved into his family home when her parents got a job there, they were the same age and she wanted nothing to do with him. She agrees that his name fits him to a T and everything he does is to make someone else mad. But years down the road when they meet again, she can't deny the feelings she has for him. She can't get him out of her head or her heart.
