Yōko(Pianist) Tanaka

Twelve-year-old Theo uses arcane knowledge and her own special talent when she encounters two secret societies, one sworn to protect the world from ancient Egyptian magic and one planning to harness it to bring chaos to the world, both of which want a valuable artifact stolen from the London museum for which her parents work.

When mummies go missing all over London, eleven-year-old Theodosia puts aside her fight against the Serpents of Chaos to save her father, who is suspected in the thefts, all the while avoiding a string of new governesses.

When a boy loses his beloved blanket and bear, they travel a great distance to make their way back to him.
