Tomorrow When the War Began by Australian author John Marsden is the story of a group of Australian teenagers who go into the bush for a few days of camping and return to find their country invaded, their town captured and their families held as prisoners. They have a choice to either surrender, or flee back into the hills. I felt that the author was able to capture the bewilderment, suspense and adventure of this situation as we read of how these teenagers cope. As a group they work through the stress, terror and desperation. While there is plenty of action to be had, Tomorrow When the War Began strikes me as more of a character study. The author develops his characters throughout the book, and by the end, these are very different people then they were when they first started out on their camping trip. The book is presented as a journal written by the main character, Ellie. We see the events through her eyes, and the author never lets us forget these are teenagers, as her written account gives as much attention to the age old teen questions of "Who is interested in who", and "Does he/she like me?". As the account is written by Ellie, what we hear about is strictly what Ellie sees and knows. As she openly admits, she didn't take any interest in current affairs so we never learn why the country is invaded or even who the invaders are. By the end of the book, these eight teens have come to realize that their lives have changed, probably forever and they must make a final decision, do they hide or do they fight? As this is the first book in the series, everything is not neatly wrapped up but the author gives us a powerful, poignant ending. I am looking forward to the next book and continuing on with this adventure.
