"Billy Halleck, good husband and loving father, is both beneficiary and victim of a nice family, and a rewarding career as a lawyer...but he is also fifty pounds overweight and edging into heart attack country.
Then, in a moment of carelessness, Billy sideswipes an old Gypsy woman as she is crossing the street--and her ancient father passes a bizarre and terrible judgment on him. 'Thinner,' the old Gypsy man whispers. Just one word...but six weeks later and niney-three pounds lighter, Billy Halleck is terrified. And desperate enough for one last gamble...that will lead him to a nightmare showdown with the forces of evil melting his flesh away."
TBR and released.

One of my favorites so far by King. AVL.
