The Fixers [EPUB ebook] 

The stakes are higher than ever in this action-packed continuation of Zane’s story.

Zane Noman had graduated from his level one lessons. This was a huge feat for a fatherless boy trapped within the confines of ECHO, the Ecological Colonies Habitat Organization, which kept him and several thousand others alive on an uninhabitable planet called Amara.

Now that his first level classes are completed, he returns to his home hub, the Pipes, for his break. He once again finds himself having adventures and hiding from dangers that will haunt him throughout his level two year of training.
