How do you like the biginning of my book? small expert!!?

You know i think it would be better if you did like a summary of the book. You know like the ones you read on the inside of the book flap or the back, because then you would get a better gist of the book and see if it really does catch your interest. I'm only saying because when i read the excerpt I was kind of confused, but of course that's just me. I do want to know why he or she was screaming. So you could say that it did catch my interest somewhat.^-^
