Jack and the Beanstalk [SF YA]

This is the first novel I completed. I am trying to decide what to do with it. It is rough; it is 20 years old. If nothing else, it may show what someone can learn about writing by practicing regularly for a long time! ;-) Please, let me know what you think. I plan on uploading every Friday about 1500-2000 word sections until it's done.

Please let me know what you think.

Thanks.
Rob
