Vintage Treasures: A Door Into Ocean by Joan Slonczewski
A Door Into Ocean (Avon, February 1987). Cover by Line
Joan Slonczewski’s first novel, Still Forms on Foxfield, was published in 1980, but it was their second novel, A Door Into Ocean, which made a real splash, winning the John W. Campbell Memorial Award for Best Science Fiction Novel (not to be confused with the old Campbell Award for Best New Writer, now called the Astounding Award, on account of Campbell being a racist goofball.)
Slonczewski is referred to as ‘she’ and ‘her’ on virtually every bio and interview I’ve found on the web — including the Kenyon College faculty page where Slonczewski is a Chair of Biology — but their website and Wikipedia page give their pronouns as they, them, theirs, so that’s what I’ll use here.
A Door Into Ocean was the book that made readers sit up and take notice of Slonczewski. They followed it with three more books in what became known as the Elysium Cycle: Daughter of Elysium (1993), The Children Star (1998), and Brain Plague (2000). Often compared to Le Guin’s The Left Hand of Darkness, A Door into Ocean explores a colony planet covered entirely by water, occupied by an all-female offshoot of humanity who have become skilled genetic engineers.
