She’s running? Senator Kamala Harris, Democrat of California, has not officially entered the presidential race for 2020, but a new piece of publishing news strongly suggests she might.

Penguin Press has announced it will publish Ms. Harris’s “The Truths We Hold: An American Journey,” in January 2019. The memoir and current-events primer, in a mixture well-known to campaign books, will include sketches of both Ms. Harris’s upbringing and her governing principles.

Ms. Harris grew up in Oakland, Calif., raised by immigrant parents, her father from Jamaica and her mother from India. She was the top law enforcement official in the state of California before becoming a United States senator.

Scott Moyers, the vice president and publisher of Penguin Press, praised Ms. Harris’s “authentic” voice, and said her back story was especially compelling, including her “fascinating and formidable” mother, the first person in her family to leave India.
