Action, Mystery, and Supernatural Adventures Await with the Original New Series, "Theodosia," Premiering Thursday, March 10 on HBO Max

Theodosia, an action-adventure HBO Max Original, is based on the critically acclaimed four-book series by bestselling author Robin L. LaFevers (published by Clarion Books, an imprint of HarperCollins Children's Books), and will begin streaming Thursday, March 10. Set in 1906, the series centers on Theo as she gathers an eclectic team that includes her younger brother Henry, along with friends Will and Egyptian Princess, Safiya, to fight a powerful secret society bent on destroying the world with ancient Egyptian dark magic.

Theodosia follows 14-year-old Theodosia Throckmorton, aka Theo, a smart, witty, supernaturally gifted teen girl who just wants to fit in and have a normal life. Theo's life is anything but normal though. The daughter of two intrepid Egyptologists excavating in the Valley of the Kings, Theo lives in the world-famous Museum of Legends and Antiquities in the heart of Edwardian London. When you live in a museum filled with cursed Egyptian artifacts, things can get weird and you just have to learn to roll with it. Theo, Henry, Will, and Safiya battle with ancient forces, dark magic, and comic chaos, all while trying to survive teenage life, get through school and save the world.

Theodosia stars Eloise Little (His Dark Materials) as Theodosia, newcomer Frankie Minchella as Henry, Nana Agyeman-Bediako (The State) as Will, and Yasmina El-Abd (Daughters of Abdul-Rahman) as Princess Safiya. Theodosia is produced by Cottonwood Media and leading broadcasters ZDF, ZDF Enterprises, HBO Max and Globo.
