Jenni Rivera's fans will get an unexpected gift this summer, when the late singer's memoir is published in both English and Spanish by Simon & Schuster, according to the Associated Press. Rivera completed the book shortly before her tragic death at the age of just 43, in a plane crash last December.

The Mexican-American singer's sister Rosie Rivera said the memoir captures the true essence of her sister's indomitable spirit. "I miss my sister every moment, but on days that I want to feel her close, I open her book written in her own words, and feel her right next to me," she said in a statement from Atria. She added that the book - entitled Unbreakable - will allow fans to "enjoy her as we have." The publisher behind the book describes it as "an intimate look into the heart and soul of this self-made woman, who ascended to the top of the charts against all odds, becoming a legend in a completely male dominated music category."

Born in Los Angeles, the Latin star started her career selling cassette tapes at flea markets before going on to sell over 15 million albums worldwide. She was noted for her work in the largely male dominated grupera genre - a type of Mexican folk music.

Rivera died along with six others following a plane crash near Iturbide, Nuevo León, México, on December 9, 2012.
