Bosch: Legacy fans are preparing to bid an abrupt farewell to Harry Bosch's solo stories after the third and final season airs in March 2025. A petition to Save Bosch: Legacy was launched on change.org in the aftermath of the cancelation, and it has garnered nearly 4000 signatures already. Now, the author of the books and executive producer on the show, Michael Connelly, has acknowledged the fans' efforts and this could really help the Save Bosch: Legacy petition in the long run.
