Taking a page from her mother, Bristol Palin is set to become an author.

The 20-year-old daughter of former Alaska governor Sarah Palin will release a memoir, titled Not Afraid of Life, this summer.

William Morrow, an imprint of HarperCollins, announced the project on Tuesday.

HarperCollins also published two bestselling books by the elder Palin, Going Rogue and America by Heart.

Rumours of a forthcoming book from the younger Palin, a former finalist on TV competition Dancing with the Stars, emerged in January when a listing for it briefly appeared on online retailer Amazon's website.

In the upcoming tome, "Bristol gives readers an intimate behind-the-scenes look at her life for the first time, from growing up in Alaska to coming-of-age amid the media and political frenzy surrounding her mother's political rise; from becoming a single mother while still a teenager to coping as her relationship with her baby's father crumbled publicly — not once, but twice," said a statement from the publisher.

"Plainspoken and disarmingly down to earth, Bristol offers new insight and understanding of who she is and what she values most."

Financial details of the book deal were not disclosed.

Bristol Palin first made headlines for her teen pregnancy during her mother's vice-presidential campaign in 2008. Interest in her continued through her troubled relationship with former partner Levi Johnston, the father of her son, Tripp.

She gained favour, however, with an engaging, girl-next-door turn on Dancing With the Stars in 2010. Palin also travels to offer motivational speeches about abstinence.
