I'm scared of seeming paranoid. Idiotic. They know I'm paranoid... How does one make an accurate of somewhere they've never been? The psychiatric model holds no more water than the flat-earth theory: don't wander beyond the well-travelled routes, for there be monsters. Don't sail too close to the edge or you'll fall off. A wry take on the eighties counterculture and noughties support groups, HUM charts Skye's journey into insanity and back. A young Sydney art student, she falls for Zane, a healer, and joins his underground pagan cult. He promises Skye and he girlfriend shamanic initiation. Instead, sex, drugs, rivalries, betrayals and lies initiate Skye into psychosis. Two decades later, still recovering, Skye consults a qualified therapist. At first, Josh seems helpful, but he runs his own cult. When his unorthodox brand of group therapy steers her towards madness again, Skye must trust her own navigation.
