“Tomorrow, When the War Began” is a book about a group of teenagers who go camping and come back to find their country has been invaded by a mysterious country. All their family members are being held in the fair grounds. They return to their camp site where they plan what to do. This story is packed with action, adventure and drama. I liked this book a lot because of all the action plus it was a fast paced book. I think any high school student who wants to read a book with non stop adventure and action would enjoy this book.
