The Author was trying to tell us how hard it was to work, move, and make a dollar. The author tells us about making a cent and a half for 1 pound of cotton. He also tells us that his family has to move year round to make money and he didn't like that because he wanted to go to school and stay with his friends, but his brother and his father had to get better jobs to support them.
Francisco reminds me of my grandma because she had to cross the border and had to work when she got older. It also reminds me of the first time I moved because I was really sad and I had to leave my friends, but he moved so much I couldn't even imagine how hard it was for him to keep making new friends and adapting to a new place.
[/spoiler] The part that got me to really like the book was the ending when he got caught by the border patrol in his classroom in front of his friends. It was really a cliff hanger at the end. The reason why I a going to read the next book is because I want to find out what happens.
