My whole class wrote expert books. I wrote about guitar. we started out by picking a topic. Picking a topic for me was semi-hard. My first topic was skateboarding, but I changed it to guitar. We started doing boxes and bullets. Then we organized our chapters. Then came the writing, I had to change many things before I perfected it. After that we typed it on to the computer. Next we added pictures, captions and all that stuff that makes it look good.
