I don’t see how she and her publisher won’t avoid a slander suit.
The charges weren’t just dropped; they were exonerated, they were declared innocent by a court opinion.
Easy. She will not repeat any charges against any individual, describe her "ordeal" only in the most general terms in Chapter 3.
Outline
Chapter 1: Her early life, family, school, hopes and disappointments.
Chapter 2: Her gradual slide into drugs, stripping, etc.
Chapter 3: Her "ordeal". Don't expect any specifics. Not one name, not even Duke or the word "lacross".
Chapter 4: The initial investigation, her story rejected by the police.
Chapter 5: Mike Nyfong, man of vision, takes up her cause.
Chapter 6: The media begin to notice. She and her case become a case celeb.
Chapter 7: The Empire Strikes Back. The dark forces of the internet and vast right wing noise machine conspire to crush her and preserve white privilege.
Chapters 8-11: More of the same. Mary Mapesque whining and "explanations. Yada yada yada
Chapter 12: The Aftermath. How this ordeal has ruined her life, causing her to relapse into drugs and alcohol, just when she was turning her life around.
Chapter 13: The future. Plans to sue ... someone. Struggling to recover from the drug and alcohol adiction caused by the stress of her "ordeal". Will fight to reveal the truth. Yada yada yada.
It's an easy boilerplate, it actually writes itself. By keeping it general, the ghost writer can save dough on fact checkers, investigators and researchers. (This will be a pretty fact free effort. Call it a guess.)
The most difficult part writing this book will be keeping the subject/author sober enough to provide even the most sketchy details.
