Imogen's Quest - John Rees Campbell

On Anseris, Imogen having a short hairstyle and wearing a chunky wristwatch would once have been serious crimes. The long line of autocratic rulers of the planet Anseris wanted to keep it as a stagnant copy of Europe's Middle Ages.

Imogen was once Princess Louise and should have been the next autocratic ruler of the planet. If fate, in the shape of an invasion from a rogue human civilization from beyond the stars, had not intervened. Sent on a mission to gain assistance from other humans, she finds herself and her cousin Anita trapped like a fly in amber. During their sleep, they fall under the influence of the digital ghost of Queen Kathyren, the insane architect of Anserian society.

Safely home, but long forgotten. With a false set of implanted memories, she became Imogen, reduced to Princess Anita's maid, her aristocratic voice replaced by a broad lower-class country accent.

When she becomes Dame Imogen, the Royal Goose-keeper, and secretly regains her memories she finds herself on a quest-using the pseudonym Johanna. She must destroy Queen Kathyren to rescue her cousin and then become the reforming Queen Anseris desperately needs.

This novel is based on The Goose Girl, a version of a folktale saved from obscurity by the Brothers Grimm. Once again retold for a new generation.
