Darkness in Hemingway family's struggles

Many people remember Mariel Hemingway best from her portrayal of the sweet teenager Tracy in Woody Allen's Manhattan, where she delivered film's uplifting closing line, a reminder, "You have to have a little faith in people".

But Hemingway herself, then only 16, was living a life with much darkness in it. Her family was plagued by alcoholism, drug addiction and mental illness. And suicide: Seven of her family members have taken their own lives, including her famous grandfather, Ernest Hemingway, in 1961, and sister Margaux, the former supermodel, in 1996.

Hemingway, now 53, has written two new memoirs, Out Came the Sun and a young-adult version, Invisible Girl, in which she frankly recounts her family's struggles.
