My Sunshine (book 1)

When Thomas and his twin sister Hannah wake up in the box together, they don't remember anything. They don't know where they are or how they got there. All they know is that they want to get away as soon as possible. Unfortunately, that's impossible. They are trapped with a bunch of other boys, much to Hannah's disliking, in the Glade. However, one glader catches her eye. Newt.
