On a good day, Hana Moss is 33.9 million miles from her hometown on Mars, but today is not a good day. Earth’s gravity weighs heavy on her, she’s lost in the sky-high labyrinth of Victoria City, and she has nowhere to sleep. When Hols Keller offers her a room to rent, Moss doesn’t ask too many questions. Within hours, she's in the middle of a crime scene, helping her new roommate investigate a murder. Who killed this retired colonial governor? How are cyborgs and AIs all over the city getting hacked when that shouldn’t be possible? Most who is Hols Keller really, and why is Moss ready to follow her anywhere? Sherlock Holmes meets the Murderbot Diaries in this queer sci-fi/mystery series.
