Theodosia Throckmorton Books in Order

The Theodosia Throckmorton books are part museum mystery, part historical fantasy, and part supernatural cleanup job. Theodosia is an eleven-year-old girl living in early twentieth-century London, where her parents run the Museum of Legends and Antiquities. The problem is that Theo can see the curses still clinging to the Egyptian objects in the collection, and almost no one else can.

That means she spends a lot of time doing secret repair work while the adults around her blunder ahead. She studies old texts, makes protective charms, and tries to keep one nasty artifact from poisoning the next person who touches it. Her cat Isis, her friend Sticky Will, and her brother Henry all help shape the feel of the series, but Theo is very much the engine. She is smart, funny, impatient, and usually the only person in the room taking the danger seriously.

Her parents are not villains, just distracted archaeologists, and that gap between what the adults think is valuable and what Theo knows is dangerous drives a lot of the comedy. It also helps the books stay lively rather than grim. Theo is often annoyed, sometimes frightened, and nearly always busy, which makes her a very easy narrator to follow.

The setting matters a lot. These books use the Edwardian fascination with Egypt, museums, spiritualism, and secret societies to make Theo's world feel busy and a little off-kilter even before the magic shows up. London is full of shadowy groups, dubious magicians, academic pride, and adults with too much confidence. At the same time, trips into tombs, storage rooms, and crowded streets give the series a strong sense of movement.

Theo would really like the grown-ups to be useful, but that rarely happens.

Across the four books, the main thread is Theo's fight against cursed objects and the people who want to use them, especially the Serpents of Chaos. There is also a quieter mystery around her unusual gifts and her connection to Egypt. The books balance spooky material with humor, quick plotting, and a first-person voice that keeps everything brisk.

Read the series in order, starting with Theodosia and the Serpents of Chaos. The magic, friendships, and rival secret societies all build on one another, and later books open the world up in satisfying ways. If you like clever child narrators, Egyptian lore, and adventures where brains matter more than brute force, Theodosia is very easy to settle into.
