Lethal trust

My name is Mercal grey the odd girl out at school I train to fight because I feel like I will need to know for later in life, but nothing prepared me for this.

Mercal is your everyday ordinary girl,
with a lot to hide. She's stronger then she seem in mind and body
And is always ready for what is to come
So what happens when her parents secret comes out and a strange man declares to be her real farther, and men keep coming after her, for the good or bad, and who will be there to help her.

Then there's Alex, who knows
What's going on inside his head,
He also seems to know more about Mercal then she knows of her self.

So how will this story end
