Strong Medicine is detective and mystery. Mark Latto travels to California to learn about a new medicine his friend, Deborah Spencer, is developing. When he arrives, he finds that Deborah is dead and the book that she was writing has disappeared. Deborah Spencer is a woman. She has enthusiasm to find new medicine which help for people who has difficult diseases. They are good relationship etch other. Medicine lead to happen unfortunate because it is so expensive and in demand.  People try to find new medicine to get much money. Most of chapter in this book is related with money and desire. I was realized that money is the root of the evil. No matter how people get money, they are willing to look for it. When I were reading it, I could obviously image story which is going on .This book was so reality by author. It’s difficult to find who murder is when I was reading this book. When I picked out this book at library, it seemed like understanding difficulty due to academic words and many character.  However, this book was more concreted  by the author. So, I could read it easily and feel fun. I really like studying English through reading English. When I finished reading it, I didn’t feel like solving a lot of question in a textbook. I want to keep improving English through reading English book. It is killing two birds and one stone.
