The book series, Alien Hunters, is a futuristic science-fiction story.
Earth is about to be conquered by an evil alien race that has already destroyed numerous planets. The only hope for our planet is a magical alien. However, that magical alien is being hunted and must be rescued.
Two brothers from Earth go on a quest to save the magical alien. They encounter numinous obstacles and must risk their life on more than one occasion.
The plot is interesting, but some of the sciences and characters are to silly to feel realistic. All in all, I would say the book series is fair.
