The JAMES TIPTREE JR AWARD-winning novel.

Change or die. These are the only options available on the planet Jeep. Centuries earlier, a deadly virus shattered the original colony, killing the men and forever altering the few surviving women. Now, generations after the colony has lost touch with the rest of humanity, anthropologist Marghe Taishan arrives to test a new vaccine. As she risks death to uncover the women's biological secret, she finds that she, too, is changing - and realises that not only has she found a home on Jeep, but that she alone carries the seeds of its destruction . . .
