Change or die!

Centuries ago, on planet Jeep, a deadly virus killed the men and forever altered the few surviving women. Now, generations after the colony lost touch with humanity, a corporation arrives to exploit Jeep's resources - and its forces find themselves fighting for their lives.

Anthropologist Marghe Taishan arrives to test a new vaccine. She risks death to uncover the native women's biological secret, and finds that she is changing too. Marghe realises that not only has she found a home on Jeep, but she alone carries the seeds of its destruction.

Ammonite is an unforgettable novel that questions the very meaning of gender and humanity. As readers share in a journey through an alien world, they too embark on a parallel journey of fascinating self-exploration.
