As someone who has read the entire series, I thought "Light" by Michael Grant was great and full of action. It was a great way to end the "Gone" series and I would recommend it to anyone who is reading the series. The book had many great fight scenes and depicted the imagery in a way that you could almost feel yourself in the story. Their was enough blood and gore to combat even "Hansel and Gretel: Witch Hunters". There is also a fair amount of romance and drama. Their is a lot of suspense as the characters are constantly alert, watching out for the evil being known Gaia who's main goal is to rule the world. This book is perfect for anyone who is looking for a read that you will not want to put away.. 
 The book tends to be a little repetitive and sometimes boring because of the repeated parts so that is why I am giving it four stars instead of 5 but if you read through it then it will get much more exciting. 
 It is a book with excitement at every turn of the page!
