Theodosia and the Serpents of Chaos

Theodosia Throckmorton, a clever and shrewd girl of sorts, has the harrowing and busy work of nullifying curses in her father's museum, where the darkest spells abound. However, it is delicate work, and time is running out for her to set things right. A crate arrives from Theo's mother in Egypt, which contains a cursed statue of Bastet. While transferring the curse from the statue to a wax figure, she becomes distracted and redirects it into her cat, Isis. Her hands are full enough when her mother returns from the tombs of Egypt, bringing countless cursed valuables and antiquities with her. While picking her mother up at the train station, Theodosia catches a street urchin named Sticky Will trying to pick her father's pocket. He informs her that someone is following her mother. Theo tells him she will be at the station tomorrow and he can tell her more about the man then. Back at the museum, they unload Theo's mother's trunks. Theo senses the curses on the artifacts. The most powerful is a gem called the Heart of Egypt, with the power to topple the whole of Great Britain and the entire British Empire.

The next day, her brother Henry returns from boarding school. The Heart of Egypt is stolen, and Theo suspects someone from the British Museum and investigates, Henry tagging along without her consent. A Mr. Tetley is acting suspiciously, and they decide to follow him. While traveling through the Seven Dials, they meet Will and witness a man taking the Heart from Tetley, then the same man is stabbed in a churchyard. Theodosia hears the man mumble "Som set hoo", or "Somerset House". He tells Theo to speak to Wigmere, only Wigmere. She sends Henry and Will to Somerset House while she struggles to keep the man alive using her amulets. Will and Henry bring help, and Theo is introduced to Lord Wigmere, head of the Antiquarian Society and The Brotherhood of Chosen Keepers, a group dedicated to nullifying curses. Theodosia is relieved to know there are others like her, but disturbed that no one else can sense the curses the way she can. Henry and Will are not told the true nature of the Keepers, although Will is taken on as a message boy later on. Theo is also angry that Wigmere may suspect her mother of stealing the Heart of Egypt, as she works closely with Count Von Braggenchnot, head of the Serpents of Chaos who will do anything to rain plague and pestilence down on England.

After Theodosia escapes, she sneaks onto a ship on which her mother and father are traveling to go to Egypt. While in Egypt, Theodosia finds a hidden part of a pyramid. She discovers that the First Assistant Curator, Nigel Bollingsworth, is the traitor. Theodosia is very clever, and uses the Egyptian version of voodoo dolls to hurt Tetley. She reaches into the pocket of her pinafore and throws sand from the tomb at Nigel, the left side of his face dissolving. Clever Theo finds another tomb and returns the Heart of Egypt to its rightful place. Theodosia finds an important artifact—the Was scepter—and hits Nigel on the head with it.

Theo is rescued by her parents and Nabir, her mother's dragoman. They return home, where Wigmere gives Theodosia a ring, and Theo becomes an official member of the Brotherhood of the Chosen Keepers.
