“Fear the Walking Dead” has tapped Maggie Grace for Season 4 of the AMC series.

According to Deadline, Grace will appear as a series regular in the next season of the zombie drama. Details about her role are being kept under wraps.

Shortly after her casting was announced, Grace took to Instagram to thank the show’s cast and crew for giving her a warm welcome. “Much thanks to the wonderful cast & crew for the gracious welcome!” the 34-year-old actress wrote. “What an impressive team! We really hit the ground running :)”

Grace, who is best known for her role as Shannon Rutherford on the ABC adventure drama series “Lost,” is the latest addition to the growing Season 4 cast of “Fear the Walking Dead.” The actress joins previously announced series newcomers Garret Gillahunt, Jenna Elfman  and Lennie James, who is reprising his “The Walking Dead” role, Morgan Jones.

The destruction of the Gonzalez dam in the Season 3 finale put the fate of every major character on the show up in the air, except for Madison (Kim Dickens), who was seen to have survived the incident at the end of the episode. But earlier this week, AMC released a photo from the set confirming that Frank Dillane, Alycia Debnam-Carey and Colman Domingo are reprising their roles as Nick, Alicia and Strand, respectively. The Hollywood Reporter also reported that Danay Garcia will return as Luciana in the upcoming season.

The addition of new faces to the show isn’t that surprising as the series looks to repopulate its world after Season 3 saw the deaths of series regulars Travis Manawa (Cliff Curtis), Ofelia Salazar (Mercedes Mason) Jeremiah Otto (Dayton Callie), Jake Otto (Sam Underwood), Troy Otto (Daniel Sharman) and Lola Guerrero (Lisandra Tena).

Aside from new characters, “Fear the Walking Dead” Season 4 will also feature a new location. As confirmed in last week’s episode of “The Walking Dead,” the series moved its production to Austin, Texas. The change of filming location was teased in the Season 3 finale, in which new villain Proctor John (Ray McKinnon) mentioned that he’s planning to set sail for “what’s left of Houston.”

“Fear the Walking Dead” Season 4 premieres in 2018 on AMC.​
