If you are looking for some good books to read I would recommend the Tomorrow series. I was reading one book a day I couldn't put them down. The movie just doesn't give them justice.
The Tomorrow series is a series of seven young adult invasion novels written by Australian writer John Marsden, detailing a high-intensity invasion and occupation of Australia by a foreign power. The novels are related from thefirst person perspective by the main character, Ellie Linton, a part of a small band of teenagers waging a guerrillawar on the enemy soldiers in the region around their fictional home town of Wirrawee. The name of the series is derived from the title of the first book, Tomorrow, When The War Began.
