Hornbacher plans to have her sixth book out in early 2019. In an interview in August 2015 conducted by Adam Walhberg of Minnpost, Hornbacher reveals more about the inspiration behind her book and the book itself. She speaks about "the new edition of DSM 5 (Diagnostic and Statistical Manual of Mental Disorders) was released and it created...an...uproar in psychiatry and brain science." In this book, she is writing profiles of 12 people who suffer with mental illness to explore these philosophical issues on a more human level.
