The 2nd in the 'Tomorrow Series'. Ellie and co are hiding out after the climax of book 1. Worried about their missing friends they sneak into Wirrawee to find out what has become of them. It is the start of a dangerous trek that that will see details about the invasion and colonization revealed, more survivors are found, there is betrayal and death.
This is good. I would prefer less scenes of them sitting around having discussions on the horrors of war though. I like these characters and hope to read books 3,4 and 6 soon.
