Nearly 20 years ago, “Bones” premiered on Fox. Now it’s time to go back and dig deeper! (Unlike the forensic excavation on the show, we don’t mean this literally.) Stars Emily Deschanel and Carla Gallo are taking you on a behind-the-scenes tour of the murders, the characters, the sometimes-grisly bodies, and everything else you never knew about the show. Launching September 18, from Lemonada Media.
