AceShowbiz - Elizabeth Anne Hanks, the daughter of beloved actor Tom Hanks, is sharing the unvarnished truth about her childhood in her emotionally charged memoir, "The 10: A Memoir of Family and the Open Road."

The book, set to be released on April 8 by Simon & Schuster, retraces her solo, cross-country journey and uncovers startling details about the past, primarily focusing on the abuse perpetrated by her late mother, Susan Dillingham.

Dillingham, who acted under the name Samantha Lewes, was married to Tom Hanks for nine years before their divorce in 1987. They had two children, E.A. and Colin Hanks.

As Elizabeth reveals, her childhood was marked by violence and instability, exacerbated by her mother's mental illness and addiction. Dillingham's struggle culminated in her death from lung cancer in 2002 at age 49.

Through her mother's diaries and family history, Hanks confronts the "darker and more violent" aspects of her upbringing, memories she had long suppressed.

Describing her home life with her mother, she wrote, "As the years went on, the backyard became so full of dog s*** that you couldn't walk around it, the house stank of smoke. The fridge was bare or full of expired food more often than not, and my mother spent more and more time in her big four-poster bed, poring over the Bible."

Eventually, her mother's emotional abuse turned physical, prompting Elizabeth to move in with her father and stepmother in Los Angeles, midway through seventh grade.

Tom Hanks, according to Elizabeth, experienced his own trauma during his childhood, which was marked by his parents' divorce and a revolving door of stepparents and siblings.

Despite the tumultuous past, he now supports his daughter's candid storytelling. Elizabeth says, "I'm equally my father's daughter because he taught me to tell the truth and move forward."

Through this journey, she realized that "the stories we tell about where we are from cannot be divided from the stories we tell about who we are."
