I, Coriander is a 2005 young adult novel by Sally Gardner, a historical fantasy set in London at the time of the Puritan Commonwealth.

Coriander Hobie is born the daughter of a wealthy merchant living on the Thames a few years before the English Civil War.

She is happy until she receives a present of silver shoes which her mother forbids her to wear and stores above a wardrobe with a stuffed alligator which scares Coriander into leaving it alone for sometime.

The first time she wears them she experiences hallucinations and disappears on a bridge with the family servant only to reappear shaken minutes later.

While her father grieves it is hinted at that her mother may not have been from the human world, and possessed a magical fairy relic that might have saved her life.

The preacher and Maud continue to abuse Coriander and tell her she must take on a more Christian name, Ann.

The preacher (Arise Fell) and Maud unleash their fury and lock Coriander in a red chest in the hopes that she will suffocate.

Coriander decides she will not let Rosemore win, and must go back to the house to claim her mother's shadow that was rightfully hers.

She returns to the house in her disguise and finds that the stuffed alligator has come to life with her mother's magic and is guarding the shadow from the preacher and Maud.

She is there in the dead of winter now, and Tycho has become a fox, still on the run from the giants for refusing to marry Rosemore's daughter.
