In 2004, almost 20 years after the fatal bombing of an Air India flight from Vancouver, two suspects--finally--are on trial for the crime. Ashwin Rao, an Indian psychologist trained in Canada, comes back to do a "study of comparative grief," interviewing people who lost loved ones in the attack. What he neglects to mention is that he, too, had family members who died on the plane. Then, to his delight and fear, he becomes embroiled in the lives of one family caught in the undertow of the tragedy, and privy to their secrets. This surprising emotional connection sparks him to confront his own losses.
