Book excerpt: Unflinching in his honesty and unabashed in his love for life, Eric Arauz first peels back the curtain on living with the trauma of severe child abuse, mental illness, and addiction to reveal the brutal truth about hopelessness and the so-called "fine line between madness and genius," and then lays out his Existential Cookbook and the literary ingredients he discovered on the road to living a joyous and hope-filled life.
