"With this book, Sally Horner takes precedence. Like the butterflies that Vladimir Nabokov so loved, she emerges from the cage of both fiction and fact, ready to fly free."

When I started this book I had never heard of Sally Horners case, nor have I read Lolita. 
This book was split into incredibly sad and incredibly frustrating.
Learning about Sally's case and her life afterwards was devastating. She lead a short life so full of sorrow, it was difficult to get through. 
The parts about Nabokov were more frustrating to me. It held alot about how he wrote and his life but it seemed like alot of fluff, or not extremely necessary to the story.  Chapter 18, When Nabokov (really) learned about Sally, really got into the bones of wether or not he knew of Sally horners case while he was writing Lolita. 
This book made some interesting connections from Sally's case to the book Lolita. While no one can say true or false expect for Nabokov, it was interesting to read about. 

"Sally Horner can't be cast aside so easily.....A girl immortalized, and forever trapped, in the pages of a classic novel of satire and sadness, like a butterfly with wings damaged before ever having the chance to fly."
