Josh Anvil is a fantastic character. I liked him very much from the very first book. He is a smart and curious fourteen (almost fifteen) year old. Unfortunately, he doesn't see himself the same way. He has low self-esteem, which is caused by his dyslexia and being bullied at school. However, he is an excellent story teller and basketball player, has a vivid imagination and incredible powers thanks to the aliens that saved him after an accident in the swamp where he lives. The story continues from the end of the third book and sees Josh dealing with the aftermath of the battle with the clones, as well as still struggling to deal with the power given to him and this manifests in a most unusual way. He finds himself having to fight against his own fears which, because of his ability to imagine things into being, begin to eat away at his sanity and confidence and takes on a life of its own. However, that's not the only challenge he faces. He still has to stop the aliens from destroying the earth. Not an easy task by any means.

This story is just as fast paced and exciting as the first three books. There are several twists and turns, and a few surprises that kept me hooked from beginning to end. There is action, adventure and danger aplenty in this story and I found myself sitting on the edge of my seat during some scenes. This book took me on a roller coaster ride of emotion and when I reached the end of the story I felt sad, but this was only because I wanted to keep reading! The story does end in a small cliffhanger, although the story arc seems to be reaching its climax, so I am now looking forward to reading the next book in the series as soon as possible.
