Meet Nic Sheff, the bestselling author of Tweak, an unforgettable memoir, who now delivers a gripping debut novel.

"As a teenager and young adult, I struggled with drug and alcohol addiction, as well as severe mental illness issues—bipolar disorder, depression, psychosis. My first two books were memoirs about my experience battling addiction. For my first novel, I wanted to continue my exploration of psychological issues within the framework of a thriller. When two of my family’s friends, both high-schoolers, were diagnosed with schizophrenia, I began researching the illness. Apparently this disease, which often lies dormant in teens, has been surfacing earlier and earlier in those with a genetic predisposition to the illness after these kids try smoking pot—because our pot is so much stronger than it ever has been. I wanted to examine what happens to someone who experiences the symptoms of schizophrenia while still a teenager, someone trying to balance the hardships of mental illness at such a fragile time of life—the everyday struggles of high school and relationships. Much of the novel is borrowed from my own experience, but it is also a departure. I hope it shows that mental illness is not a death sentence."
