Ethan of Athos
Lois McMaster Bujold
 It tells the story of Dr. Ethan Urquhart, Chief of Biology at the Severin District Reproduction Centre on the planet of Athos, and his quest to Kline Station to find out what happened to a shipment of vital ovarian tissue cultures. Athos was founded and maintained as an exclusively male-populated planetary colony, and a planetary religion and ideology supports this single-sex structure. Their continuing reproduction relies on uterine replicator technology and ovarian tissue cultures. However, after 200 years of service, the ovarian cultures introduced by the original colonists are deteriorating into senescence. The Population Council orders new ovarian cultures from another planet, Jackson's Whole, but upon delivery discover they have received an unusable mixture of dead and animal tissues. The Council appoints Ethan their planetary ambassador and sends him offworld in search of a fresh batch of tissue cultures, and (if possible) a refund from the original supplier, House Bharaputra. This is considered to be a very daring assignment as it means contact with women, who Athosians are taught are demonic and terrifying. This impression is only reinforced by the men who periodically move to their planet from the wider galaxy and report upon the horrors of womankind. Ethan's first encounter with a woman occurs when he asks directions from Commander Elli Quinn, a rather unorthodox intelligence officer with the Dendarii Free Mercenary Fleet, who is on home leave for the first time in ten years. Many men stare at Quinn, though the reasons why are a mystery to Ethan (it turns out that Quinn's face was surgically reconstructed to be extremely beautiful). Ethan learns that women in general are not the monsters he was taught they were; they are as varied as men and range from honorable to devious to helpful to selfish. Ethan quickly gets embroiled in some trouble: he is attacked by military agents from Cetaganda who are seeking the fugitive Terrence Cee as well as the lost tissue cultures, but Elli rescues him. Terrence, who approaches Ethan with a request for asylum, turns out to be the last surviving creation (originally labelled as L-X-10-Terran-C) of a Cetagandan genetic project to create telepaths. Although his telepathy is reliable, it has a small range and can only be triggered for a short amount of time by ingesting large doses of the amino acid tyramine. Terrance’s female counterpart, Janine (J-9-X-Ceta-G), was killed in their escape, but he managed to preserve her body and convey it to Jackson's Whole, where he bribed House Bharaputra to splice her genes into the ovarian cultures that were purchased by Athos. Terrence had intended to escort the cultures to their destination on Athos but was delayed on his way to Kline Station, and is now horrified to learn that the cultures were stolen and replaced by the useless material that ultimately arrived on Athos. After Terrence's departure from Jackson's Whole, the Cetagandans attacked House Bharaputra, killed the researchers who had worked with him, and destroyed their records. These Cetagandans then followed him to Kline Station, and are the same agents who attacked Ethan. In turn, the Bharaputrans hired Elli to track down the Cetagandan agents, although she is also gathering information for the Dendarii. It turns out that for petty personal reasons, a minor official on Kline Station "threw out" the Bharaputran tissue cultures that contained Janine's genes. Elli defeats the Cetagandans and attempts to recruit Terrence to the Dendarii, but he is far more attracted to the isolated, uncomplicated life on Athos. He does give Elli a small genetic sample to take back to the Dendarii, but not before Ethan asks her for (and receives) one of her ovaries to create a new tissue culture. After her departure, the original Bharaputran shipment unexpectedly turns up intact and usable, not destroyed. Ethan buys a new set of ovarian cultures anyway as a cover, uses their packaging to relabel the cultures with Janine's genes, and returns with them and Terrence to Athos. Elli's donated ovary culture is an additional, 451st culture. [Note: The events of the novel are obliquely referred to in the novels Cetaganda and Borders of Infinity.]
