Terrible book. It for sure can’t take place in USA. It is like a 19th century story. Who would allow their in laws to treat you as slave and make you sleep in the Garden. Run from it.
IDK collect the dragon balls I guess? Nah, but if you want to get better at writing, you just need to put in the effort. The more you do it, the better you get, playing word games and reading works pretty well too.
