DECOHERENCE

Sebastian Shockley lost his mother to cancer and his father to suicide, but he's just struck lucky, because he's just written a best-seller. His success is short-lived, though, because he's then diagnosed with an untreatable brain tumour that gives him vivid, macabre hallucinations. When he's contacted to take part in a study of an experimental cure, he his given some hope but maybe the cure is worse than the disease; or maybe there isn't a cure at all. As the study proceeds, he begins to believe that there are secrets all around him and he starts to wonder if there's something terribly wrong with the reality in which finds himself; if, in fact, reality has no existence for him any more.
