Some final words from the late Mexican-American singer and TV star Jenni Rivera will be out this summer.

Atria Books announced Monday that it will publishing a memoir by the multimillion-selling artist, who died in a plane crash in December at age 43.

"Unbreakable" is scheduled to come out in July, in English and Spanish language editions. It has been authorized by Rivera's family.

Rivera (shown here at an August 2012 press conference) had been working on "Unbreakable" for several years. Atria says "Unbreakable" will reveal the "heart and soul" of Rivera, a mother of five and grandmother of two known for her frank talk about her life. Born in Long Beach, Calif., Rivera went on to sell more than 15 million copies of her 12 major-label albums.
