Some final words from late Mexican-Am- erican singer/TV star Jenni Rivera will be out in summer.

Atria Books says it’s publishing a memoir by the multimillion-selling artist, who died in a plane crash in December at age 43. “Unbreakable,” coming out in English and Spanish, is scheduled for July and has been authorized by Rivera’s family.

Rosie Rivera, the late singer’s sister, said the family had decided to share Rivera’s book with her fans. Rivera had worked on “Unbreakable” for several years and completed it before her death, an Atria spokesman said. She had been in talks with Atria since 2011. Rivera sold more than 15 million copies of her 12 major-label albums.
