The first book I would recommend is the Hunger games by Susan Collins. The novel is about a teenage girl who is forced to participate in the Hunger games. This is an event in which one boy representative and one girl representative from every district to fight in a game to the death in which the winner gets a great reward. This also introduces a love interest to katniss everdeen the main character.
Now I would like to recommend a film called Red Dawn. Red Dawn follows an extremely similar story line to Tomorrow when the war began. It starts of when a small town is invaded and a small group of teenagers escape. These teenagers work together to rebel against the invaders and form a group called the wolverines. I would highly recommend this movie as it also stars some great actors such as Josh Peck and Chris Hemsworth.
Well that's it from me viewers thanks for reading and I hope you enjoyed the review.
