Throughout the pages of “Walking Disaster,” Whibley describes a fraught and frightening relationship with Sum 41’s first manager, Greig Nori, whom the singer alleges groomed and sexually and verbally abused him for years, starting when he was 16 and Nori was 34.

Back in the pop-punk heyday of the early aughts, Sum 41 was one of the biggest bands on the planet. Deryck Whibley, its spiky-haired frontman, was known for destroying hotel rooms and dating fellow tabloid staples like Paris Hilton and Avril Lavigne.

The musician opens up for the first time about the alleged abuse and grooming in his new memoir, "Walking Disaster: My Life Through Heaven and Hell."
