In this remarkable memoir, one of Scientology's highest-ranking defectors exposes the powerful cult's secret inner workings. Raised in Scientology, Mike Rinder became the organization's international spokesperson and head of its powerful Office of Special Affairs. He negotiated Scientology's pivotal IRS tax exemption and engaged with prominent celebrity members, including Tom Cruise, Lisa Marie Presley, and John Travolta. Yet Rinder couldn't shake a nagging feeling that something was amiss-founder L. Ron Hubbard's promises remained unfulfilled, and his successor, David Miscavige, was ruthless and vindictive, unhesitant to confine many top Scientologists, Mike among them, to a makeshift prison known as the Hole. In 2007, Rinder finally escaped. Overnight, he became one of Scientology's biggest public enemies, subject to a relentless campaign of harassing and intimidation. Determined not to back down, Rinder continues to help people break free to this day. In A Billion Years, the dark, dystopian truth about Scientology is revealed from an insider's perspective as never before. Rinder's life story is harrowing and also one of remarkable personal resilience.
