The decades-long manhunt for a serial killer takes a stunning turn in a haunting and harrowing true crime shocker by Gregg Olsen, the #1 New York Times bestselling author of If You Tell.

In 1990 in Washington state, the bodies of Yolanda Sapp, Nickie Lowe, and Kathy Brisbois were found on the banks of the Spokane River. They were part of a close-knit alliance of sex workers whose oath to protect each other was, in the end, hopeless. For twenty-two years their brutal murders went unsolved.

In 2012, a DNA cold hit pointed to Douglas Perry. A repeat assault offender, Douglas was currently incarcerated in Carswell, Texas. But there was a twist: The facility was for female prisoners. The man authorities hunted for decades was now Donna Perry. Her gender reassignment not only helped to mask the evil deeds of the past, it ended a life of childhood traumas and a pent-up rage unleashed on nearly thirty victims, according to Donna herself. Through total reinvention, she believed she’d finally slayed the monster within.

By the River’s Edge is the astonishing true story of an elusive serial killer, an escape plan like no other, and the women who lived and died on the fringes of the Lilac City for whom justice was at long last served.
