By Jessica Hulsey

"I’ve now worked to support those struggling with addiction for 28 years. This book by Jessica Hulsey is the most important guide to action I have ever read. Jess has a voice of enormous comprehension and compassion. She is the child of a multigenerational family savaged by chronic substance use disorders. A Princeton grad of courage and great leadership. This compelling and brilliantly written book is a guide not just to understanding the tragedy of SUD … but also a strategy for families to act."
