Midnight Rider [EPUB ebook] 

Rikki is generally content with his life and the world in which he lives. That is until the day a mysterious big cat emerges from living underground and reveals the hideous truth about Rikki’s society. While Rikki trains his fire-breathing horse for a community event, the confused teenager must navigate a dark path of twisting and evolving morals. When the previously helpful cat suddenly becomes a violent predator, Rikki must either act in line with his own morals or witness his town succumb to the wrath of the beast.
