Lindsay Ellis is making her fiction debut! The Hugo-nominated critic, documentary film-maker, and YouTuber took to Twitter on Wednesday to announce the details of her first novel, an “alternate history first-contact adventure” called Axiom’s End.

Here’s the synopsis:

By the fall of 2007, the scandal over whether the U.S. government has been hiding living aliens has reached a fever pitch, and it is all Cora Sabino can do to avoid the whole mess. The force driving this controversy is Cora’s whistleblower father, and even though she hasn’t spoken to him in years, his celebrity has caught the attention of a furious government. But she neither knows nor cares whether her father’s leaks are a hoax, and wants nothing to do with him—until one of the aliens finds her.

To this creature, codenamed “Ampersand,” Cora, like all humans, is an object and nothing more. Desperate to locate his imprisoned fellows, Ampersand, unique in his ability to understand human language, abducts people with ties to the leaks, pumps them for information, and disposes of them—and Cora is next.
