The Science Fiction and Fantasy Writers of America is holding its Nebula Awards conference in Los Angeles this weekend, and tonight, the group announced the winners of the 2019 Nebula Awards, which honor the best science fiction and fantasy writing from 2018.

Mary Robinette Kowal’s The Calculating Stars, the first installment of her Lady Astronaut series, took home the top honor. The novel (and its companion, The Fated Sky) are set in an alternate history in which an asteroid landed off the coast of North America in 1953, setting off a climate catastrophe. To prevent the extinction of the human race, various nations around the world kick-start an alternate space race to colonize the Solar System before it’s too late.

The book’s central character, Emma York, is a former WASP who served during World War II and finds herself — and her fellow female pilots — shut out of the selection process to become an astronaut, and fights to ensure that they’ll be part of the space program. In addition to last year’s The Fated Sky, Kowal has added to the world with a number of short stories — “The Lady Astronaut of Mars” (which won the 2014 Hugo Award), “We Interrupt This Broadcast,” “Rocket’s Red,” “The Phobos Experience,” and “Articulated Restraint.” Fans of the series can also expect two additional Lady Astronaut novels in the near future: The Relentless Moon will come out in 2020, while The Derivative Base will arrive in 2022.

Other winners tonight were Aliette de Bodard for her novella The Tea Master and the Detective; Brooke Bolander for her novelette The Only Harmless Great Thing; and Phenderson Djèlí Clark for his short story “The Secret Lives of the Nine Negro Teeth of George Washington.”
