Author Arleen Williams, whose sister Maureen was a victim of the Green River Killer, will appear at 7 p.m. Tuesday, Sept. 30 at the Issaquah Library.

Williams, who grew up in Issaquah, recently published “The Thirty-Ninth Victim: A memoir.”

The description of the event reads: “With amazing candor, Arleen Williams tells the story of her family’s journey, before and after the Green River killer murdered her sister Maureen and left her body in a stretch of wilderness off the west side of Highway 18. As insightful as it is heart wrenching, The Thirty-Ninth Victim gives you a window into the family dynamics that contributed to this life-altering tragedy. This is a memoir unlike any other. The author set out to tell Maureen’s story, but in doing so, she tells bits and pieces of every family’s story. You cannot read this profoundly personal and cataclysmic tale and come away unchanged, nor will you ever view your own family in quite the same way. You will applaud Ms. Williams’s courage in sharing this recounting of her family’s trauma through one of the most atrocious streaks of serial killings in American history. And like the family, you will never forget The Thirty-Ninth Victim.”

The Issaquah Library is at 10 W. Sunset Way.
