The book Dark Hills Divide, written by Patrick Carman, is about a twelve-year-old girl called Alexa. There are walls there to protect everyone and Alexa but she can't overcome her curosity. As the person who built the walls, Warvold, dies Alexa is left with a whole lot of mysteries she has to solve.
The characters excluding Alexa and Warvold are James Daley, Ganesh, Grayson, and Nicholas. These are peole living inside the walls. The animals friends of Alexa are Ander, Murphy, Darius, Malcom and the forest council.
The things I liked about the book were the characters and the unpredictable mysteries. I liked the book and there was nothing that made me dislike it. Overall, I thought the book was fantastic and I recommend it to students in school and you can try reading it to!
