Heading out for a week of camping in the Australian bush, Ellie and her friends have no idea that there will be nothing to return home to. Fixated on roughing it, gossiping, and various teen intrigues, the kids are shocked to discover their home deserted and their families missing when they get back. In this dystopian, post-apocalyptic young adult novel, the safety and security of home completely disappears after invaders take over and hold the town hostage. Giving themselves up, or returning to the outback and fighting are their choices, and the kids decide that guerilla warfare is the only answer. This is the first book in the wildly popular Tomorrow series.
