This is the second book in the Tomorrow series. It's more violent and more adventurous than the first. They kill more soldiers and there are more attacks. Because of this, Ellie feels guilty and feels 'shadows' following her. 'I live in the light, but carry my dark with me' is how she describes what she is feeling. The group continuously change from young and naive teenagers to more experienced and strategic people. They are more careful and aware of the situation that they are in. They are already giving each other advise on how to keep calm when they are attacking and aren't as clueless as they were in the start of the first book. 'When you're scared you can either give in to the panic and let your mind fall apart, or you can take charge of your mind and think brave.'
