The Pigman's Legacy (The Sequel to The Pigman) (Paul Zindel Classic Novels)

Four months after the Pigman died, John and Lorraine are passing by their old friend's empty house when they receive the shock of their lives: An elderly man has taken up residence in the abandoned home. Convinced this down-and-out recluse is a sign from beyond the grave, John and Lorraine decide they've been given a chance to make up for what happened to the Pigman -- a chance to make things right, once and for all.
