NEW YORK (AP) - In a newly published memoir, Jaycee Dugard
recounts in wrenching detail the rapes, isolation and heartbreak
she endured during 18 years as a kidnap victim twice impregnated by
her captor.

Dugard says she had two primary motives for writing the book, titled "A Stolen Life."

She wants to give a precise account of the ordeals that Phillip and Nancy Garrido inflicted on her. And she also hopes that her story might be of help to people facing crises of their own.

"You can endure tough situations and survive," she writes.

Dugard was kidnapped near her California home in 1991, when she
was 11, then sexually abused and held captive for 18 years. The
couple pleaded guilty earlier this year and received lengthy prison
sentences.

Now, Dugard is sharing the secrets she harbored for decades, including what happened the day she was kidnapped.

Dugard was kidnapped while walking to her Tahoe, Calif., school in June of 1991 by the Garrido couple.

She was then just an 11-year-old girl who loved her mom, her baby sister, the family cat.

Now, she's a survivor and mom who has endured the cruelty of a man that kidnapped, handcuffed, raped and imprisoned her in a backyard compound. Dugard gave birth to two girls while held captive in the backyard.

The sounds of the locking doors at the compound still haunt her and she can still remember the day her life changed forever.

On June 10, 1991, as Dugard left her home wearing all pink and a kitty shirt, and thinking about her mom -- who was running late that morning and didn't kiss her goodbye, she was taken.

Garrido used a stun gun to shock Dugard. She tried to scoot into the bushes.

The last thing she remembers touching was something sticky.

After she and her daughters were freed and reunited with her family in 2009, Dugard began asking people to bring her pinecones, not realizing that it was the same sticky thing she clung to trying to maintain her freedom.

"Back then [the pinecone] was the last thing I touched. You know, the last grip on me. Now, it's—it's a symbol of hope and new beginnings. And that—there is life after something tragic," Dugard said.

Dugard wears around her neck a small symbol of a pinecone to symbolize her new life and the hope she held onto during her imprisonment. Dugard said that during her ordeal, she constantly thought of her mother and hoped to see her again one day.
