Winchester High…. There Will be Blood
Levi Darker is a new art and literature teacher at Winchester High. Set in the future -exactly 18 years from 2013 in a small town in Michigan- technology has advanced, and the old government of the United States of America has been eradicated and rebuilt. When a horrifying string of murders begins, Levi takes it upon himself to stop the murderer before all of his students are killed. Will he be able to save them in time, or will the killer get away with everything?
