Troubles of a teenage tyrant

The beginning (chapter One)

Jack wakes up in an alleyway.

"Where am I?" Jack was wondering aloud. Looking further, he noticed billboards and car's, bright lights and fancily dressed people. He sees sketchily dressed females approaching him. "Who are you?" 

"You already know who we are! Don't act like you don't recognise us!" The most outlandish one retorted.

Jack thought for a few seconds, "Do I? I don't recall anything." 

"Are you mocking us, kid?!" A shredded woman with a mohawk yelled.

Jack got into a fighting stance. "What am I doing?"  

"You going to fight us, huh?" They began to get into fighting stances too. Jack subconsciously noted that one of the three people had a shaky leg.

Before a fight could erupt, there was the screech as a brick hit the mohawk menace in the back of the head.

"Jack! Hurry up and run!" Standing there bewildered, Jack did, in fact, not run. That was until a girl about his age manhandled him and ran off with him.

"Who are you?" Jack asked politely.

"Don't be stupid; I am your sister!" The so-called sister yelled.

Jack was shocked. "I have one of those?".

"I will leave you back with those thugs." 

"I will be quiet now," Jack murmured in silence.

They arrive at their "house", and their "Mother" came out to greet them.

"You went missing again! What have I told you about going out there?! It's dangerous for a young boy like you. Do you not remember what happened in the war?!" 

"War?" He tilts his head.

"Don't joke with me, boy!" The mother yelled.

"I am serious. I don't know where I am. I don't even know who I am, and I don't know who you are or why I am here." Jack said truthfully.

"Do you have amnesia or something?" The sister asked.

"Perhaps, I don't know." Jack tried his hardest to remember and failed epically, looking like an Idiot.

His "father" chimes in. "My son, your name is Jack Serris, you are the same age as your sister Rachel here, sixteen. You are an intelligent young lad, but on occasion, you wander off as you did again. The 'war' your mother is referring to is the second great war, where most of the male populace was wiped out and female, through both evolution and need, became the dominant gender."

"I understand," Jack responded, not understanding anything. 

"I see the look on your face; you understand none of this. We are taking you to the doctors."

Jack understood what Doctor meant, and entirely on instinct, ran to his room.

"Why did I run here of all places? It looks so... Me who ever lived here but have an amazing sense of style." As he looks around, he sees several objects of note, A queen-sized bed, a desk with a small computer, And a bookshelf filled with different books. One book, on the other hand, looked very out of place. It was a large black book with odd inscriptions; carving's in another language, the book called him. Yet another book called to him, a much smaller one in coloured writing, it was a comic titled "The wonderful deeds of Supra man." 

His sister enters the room. 

"Jack, are you doing okay? It must be hard for you to understand everything going on."
