Welltower is classed as a young adult sci-fi thriller. However, I believe it is something more. This is from the book's Explanation: "This definitely is not your average formulaic science fiction shoot-‘em-up; its purposes are to point out the state of today’s societies and to propose solutions, which is an obligation I feel with all my work. Like our society at times, the story can be brutal; however, a strong spiritual quotient is woven throughout. Books two and three broaden and continue these concepts."
