Jamie-Lynn Sigler joins Big Sky for Season 2

Deadline

The Sopranos alum is one of seven new additions to the ABC David E. Kelley series. Sigler will play Tonya, "who works as a waitress at a local diner," according to Deadline. "She and her boyfriend have big plans, that is until he mysteriously disappears. Tonya hires the services of Dewell & Hoyt to find her boyfriend, but she is withholding some secrets of her own. Like all of the women in this town, it would be unwise to underestimate Tonya."
