A Guardian Pick for 'Best Memoirs and Biographies of 2025'
A New York Times Book Review Podcast's 'Books We're Excited About in Early 2025'

Rosemary Woodruff Leary has been known only as the wife of Timothy Leary, the Harvard professor-turned-psychedelic high priest, whose jailbreak captivated the counterculture and whose life on the run with Rosemary inflamed the U.S. government. But Rosemary was more than a mere accessory. She was a beatnik, a psychonaut and a true believer who tested the limits of her mind and the expectations for women of her time.

Long overlooked by those who have venerated her husband, Rosemary spent her life on the forefront of the counterculture, working with Leary on his books and speeches, sewing his clothing and shaping - for better and for worse - the media's narrative about LSD. Ultimately, Rosemary sacrificed everything for the safety of her fellow psychedelic pioneers and the preservation of her husband's legacy.

Drawing from a wealth of interviews, diaries, archives and unpublished sources, Susannah Cahalan writes the definitive portrait of Rosemary Woodruff Leary, reclaiming her narrative and her voice from those who dismissed her. Page-turning, revelatory and utterly compelling, The Acid Queen shines an overdue spotlight on a pioneering psychedelic seeker.
