One of the most respected writers of hard SF, it has been more than ten years since Joan Slonczewski's last novel. Now she returns with a spectacular tour de force of the college of the future, in orbit. Jennifer Ramos Kennedy, a girl from a rich and politically influential family (a distant relation descended from the famous Kennedy clan), whose twin brother has died in an accident and left her bereft, is about to enter her freshman year at Frontera College. Frontera is an exciting school built with media money, and a bit from tribal casinos too, dedicated to educating the best and brightest of this future world. We accompany Jenny as she proceeds through her early days at school, encountering surprises and wonders and some unpleasant problems. The Earth is altered by global warming, and an invasive alien species called ultraphytes threatens the surviving ecosystem. Jenny is being raised for great things, but while she's in school she just wants to do her homework, go on a few dates, and get by. The world that Jenny is living in is one of the most fascinating and creative in contemporary SF, and the problems Jenny faces will involve every reader, young and old.

Gay characters, diverse cast

A Door into Ocean is the novel upon which the author's reputation as an important SF writer principally rests. A ground-breaking work both of feminist SF and of world-building hard SF, it concerns the Sharers of Shora, a nation of women on a distant moon in the far future who are pacifists, highly advanced in biological sciences, and who reproduce by parthenogenesis--there are no males--and tells of the conflicts that erupt when a neighboring civilization decides to develop their ocean world, and send in an army.

all-female world

The pristine city of Elysium floats on the water world of Shora, inhabited by 'immortals' who have succeeded in unlocking the secrets of life. Outsider Blackbear Windclan wants to share the secret of immortality with his own people, but can he, and the City of Elysium, survive the corruption and decadence that immortality has bred into the ageless society. And what of the consciousness of self-aware nano-sentient servitors and their quest for vengence?

Multiple cultures: one matriarchal (with corresponding language) and non-white, one is the all-female Sharers from A Door Into Ocean, and the other accepts same-sex relations freely.
