ZeRo Method - A brief novel about liberation from suffering? Or a manual to reset your damn head?

ZeRo Method.  A brief novel about liberation from suffering?  Or a manual to reset one's fucked-up head?  Francesco, the protagonist of this tale, will soon realize it at his own expense, or rather at the expense of his poor ego.  Poor Francesco, overwhelmed by the useless problems of an ordinary man, will randomly encounter the mentor of his life, who will adopt a strange method of liberation from the problems of everyday life: a method made of paradoxes, ambushes, renunciations, macabre contemplations, internal struggles against his own brain, fake funerals, outings in the afterlife.  In the end, Francesco will find himself retracing his life once more, but this time he will do so backward, all the way back to point zero.
