Among the Imposters is the second book in the series called "Shadow children." In this book Luke sees a shadow from the kitchen window. He decides to take a risk and go to that house to see what it is. He hopes it is also another third child like him. He meets a girl named Jen . They get along great until he finds out that she wants to protest in front of the government building. Jen has something unexpected happen to her at the end. I would recommend this book because it has a lot of unexpected twists and turns as you read.
