Theodosia is a brand new fantasy adventure that's just arrived on HBO Max. Set in 1906, the series follows Theo, a clever youngster who's obsessed with everything to do with Ancient Egypt and is based on the Theodosia series of childrens' novels by Robin L. LaFevers.

The new family-friendly series sees Theo discovering that Egyptian curses and magic are not simply myths but very real indeed, and this shocking revelation ends up thrusting her and her friends into a battle with a secretive society bent on destroying the world as it currently stands.

What is Theodosia about?

The official synopsis for Theodosia reads: 

"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."

Frankie Minchella plays Theo's younger brother, Henry, with Come Away's Nana Agyeman-Bediako featuring as Will and Yasmina El-Abd (Finding Ola) rounding out the gang as Egyptian Princess, Safiya.
