The Reaper [EPUB ebook] 

A sci-fi parable on the consequences of personal freedom taken to extremes.
Reece Pargeter is a normal seventeen-year-old schoolboy who has no real idea what he wants to do with his life. But that all changes when he has a consultation with a career advice counsellor and discovers that his destiny is already mapped out for him.. He is to become a Reaper, reporting to Mr Grimm.
Leaving the corporeal world behind for the ethereal Control, Reece learns how to reap and soon discovers he’s not best suited for the job. However, reaping isn’t the kind of job where a resignation letter is enough to be released from employment.
