Into hard (biological) SF? Fancy an anthology with top name writers produced in collaboration with the European Astrobiology Institute? That’s your serious speculation on alien life right there. The only catch is that it is currently on Kickstarter, so it needs pledges in order to happen. But look, it will include stories by Mary Robinette Kowal, Peter Watts, Premee Mohamed, Gregory Benford, Tobias S. Buckell, Julie E. Czerneda, Malka Older, Stephen Baxter, Bogi Takács and many more. And it is co-edited by my good friend Julie Nováková. The title is Life Beyond Us, and you can back it here.
