"Drawing on evidence from trusted Houston family members, friends, and other inside sources, Halperin paints a portrait of Bobbi Kristina's downward spiral following her mother's death, including drug abuse and abusive relationships," the book's Amazon page promises.

"How did Bobbi Kristina end up facedown and unresponsive in a bathtub, almost exactly three years after her mother's mysterious death? What was her relationship with Nick Gordon really like?

"How did a childhood in the spotlight as the daughter of controversial pop royalty lead to her troubling fate? Halperin offers readers a fascinating and candid behind-the-scenes look at the glamorous world, personal demons, and never-before-told life of Bobbi Kristina Brown."
