Cissy Houston, mother of Whitney Houston, has signed a deal with HarperCollins to tell the story of her megastar daughter’s life. The currently untitled book, which is described as the late singer’s “unabridged and unbelievable story,” is slated for February 2013.

“When I lost my daughter Nippy [Whitney Houston’s nickname], the world lost one of the most beautiful voices and an extraordinarily beautiful and charitable woman,” Cissy Houston said in a statement. “In sharing our story in this book, I hope to give her fans something to treasure, the way we all treasured Whitney. We are still receiving thousands of letters each day from her fans, and I hope reading this book will provide a deeper understanding into my daughter’s true story.” According to the press release from HarperCollins, the memoir won’t shy away from the darker aspects of Whitney Houston’s life, including her turbulent marriage to Bobby Brown and her drug use.

While the financial terms of the book deal have not been made public, some of the proceeds will go to the New Hope Baptist Church in Newark, N.J., where Whitney grew up singing in the choir and her funeral was held.
