Family Matters by Rohinton Mistry

Nariman Vakeel, a seventy-nine-year-old Parsi widower, beset by Parkinson's disease and haunted by memories of the past, lives in a once-elegant apartment with his two middle-aged stepchildren. When his condition worsens he is forced to take up residence with Roxana, his own daughter, her husband, Yezad, and their two young sons. The effect of the new responsibility on Yezad, who is already besieged by financial worries, pushes him into a scheme of deception. This sets in motion a series of events - a great unravelling and a revelation of the family's lovetorn past - that leads to the narrative's final outcome.
