Sentinel Station by Brittany Rose

Maya Adams is a professor of linguistics and ancient languages at Harvard University. She isn’t well liked by most of her older colleagues, mostly because her doctoral dissertation invalidated much of their earlier career conclusions and papers. Her relative youth and exotic beauty further served to draw lightning to her career by her backstabbing colleagues with unfounded rumors.
Her life changes on the night the vast alien space station appeared in the sky, visible in orbit to the naked eye. To the world’s surprise, the station is discovered to be completely abandoned. Except, the teams boarding the station can’t read the language, and she’s called on to assist, reluctantly.
She agrees, only to find out things aren’t what they appear to be, and the stakes are nothing less than the future of humanity, and the Earth itself. If she can figure it out in time, and if she could convince the people around her of the truth, which wouldn’t be easy.
