In her newest book, Girls and Their Monsters, Audrey Clare Farley addresses the Morlok quadruplets’ earliest years as a singing-and-dancing sensation and zeroes in on their coming of age and eventual descent into schizophrenia.

“I want to stress that I don’t view the quadruplets only as victims. They looked for and found joy. The book is about people living under fascism, but it’s also about bravery and defiance.”
