Diane Keaton memoir an ode to her mom

Actress Diane Keaton explores the mother-daughter relationship in "Think Again," a memoir that hits store shelves today.

The book, published by Random House, juxtaposes entries from her mother's journal with reminiscences from her own life, when she was the same age or going through the same stage. It's clear from some of the entries that her relationship with her mother, whose maiden name - Keaton - she adopted as a screen name, was central to her life.

Dorothy Keaton was 86 when she died in 2008 after a 10-year struggle with Alzheimer's disease. Her Oscar-winning daughter, a single mother who adopted two children in her 50s, is 65.

Though their lives couldn't have been more different, their perspective in many cases was similar.

This is not the gossip-filled memoir that some readers like to get from stars. Keaton does talk about the leading men in her life - Woody Allen, Al Pacino and Warren Beatty. But she also talks about a lot more: fame, fashion, seeking the spotlight, motherhood and the empty nest.
