The author of I Know What You Did Last Summer is Lois Duncan. This book is a very suspenseful mystery story about four teenagers. The main characters in the book are Julie, Helen, Barry, and Ray. Some of the major events in I Know What You Did Last Summer are when Julie gets a note about something that she and three of her friends did last summer, Helen gets a picture of a boy on his bicycle, and Ray gets an article that was cut out of the paper about the accident. Then, Barry gets shot by a mysterious person, Helen almost gets killed, and Julie almost dies.
I absolutely LOVE this book. It is so suspenseful and mysterious, and I like suspenseful things. It was especially suspenseful when someone said that they were going to get Julie, Helen, Ray, and Barry because of what they did. This book starts off interesting and exciting. I think it does because it was very mysterious. It was mysterious because someone that the four friends did not know about what, or who, was coming after them and sending things to them. I feel like I am right there in the book with the characters. This is most likely the most suspenseful that I have read in my whole life.
I think the theme in this book is "Count on your friends to help you." I think so because Barry and Julie think that there is no point in living and that this is the end for them. Then, amazingly, their friends Helen and Ray help them get through their stage. If you are a person who likes mysterious things in life, you should definitely read I Know What You Did Last Summer.
