Seventeen-year-old Samantha knows she will never be more than who she is(i read this a few times but still didn't understand it), it wouldn’t be fair to others(how? is she a magician?). Society’s rules to be equal are simple, share everything and everyone(<--start the query from here). Government is abolished, technology is sparse, and emotions are limited. If you can’t accept equality, you are given a choice: death or exile to the South- a barren wasteland in which few survive. Almost everyone chooses death.
But the one thing Samantha refuses to share are her lifelike dreams of Hawke(what's this?). When the young man(I thought Samantha was a woman) visits her dreams, he stirs up emotions she has never felt, and in a world where nothing is hers, she wants to keep him for herself. He makes her feel more, want to be more…until it’s revealed by Headquarters that Hawke is real and he is extremely dangerous(put this in active voice). Confused and afraid, she reluctantly looks for clues as to why she dreamt of him in the South, only to land in the arms of Hawke himself. But the wasteland she dreaded is nothing like the thriving city below its surface. Not only does she find answers, but the true meaning of sacrifice. Samantha knows that Headquarters will do anything to keep Hawke, and those fighting for the South a secret…even if it means their death. She must decide if she will stay in the safety of the South, or risk everything and go back to the society she knows to save the ones she has grown to love(is this: to save the ones she has grown to love, she will go back to society
or is it
she will go to the society that is known to save the ones...).
I suggest breaking this in 3 paragraphs. That would help to read it. Maybe remove words like: 'only to land in the arms' and 'is nothing like' 'true meaning' 'do anything'
They're too cliche and act as fillers. JMO.
