Do Not Resuscitate eBook

A dying man tells his great granddaughter that he has signed a Do Not Resuscitate document, giving instructions for medical personal to let him die if he's determined to be brain dead. He's invited on a long journey that he thinks is taking place in his subconscious mind as his body is being kept alive against his wishes. What unfolds before him may be an elaborate hallucination caused by the psychedelic effect of the anticholinergic drugs being pumped through his body, or are these strange and cathartic events actually happening?
