Perfect for you if...

You enjoy sci-fi mysteries with genuinely funny banter and a protagonist who'd rather eat chocolate than deal with rich people's problems.
You like your detective stories grounded in character work rather than flashy action sequences.
You're looking for the first book in a completed series you can actually finish without waiting years for the next instalment.

Maybe not for you if...

You want hard sci-fi worldbuilding with extensive technical explanations of how space stations work.
You prefer your mysteries dark and gritty without comedic relief breaking the tension.
You need your protagonists to be confident heroes; watching someone reluctantly solve crimes whilst worrying about rent isn't your speed.

About this book

Triana is a bot-programmer on Station Kelly Kornienko who prefers to avoid the wealthy residents on the upper levels. Her priorities are staying under the radar and eating chocolate. When one of her cleaning bots discovers a dead body, her routine is disrupted. Security agent O'Neill approaches her with information about missing bodies and pressures her to cooperate with his investigation or risk losing her job. Triana agrees to help, using her programming expertise to assist O'Neill. Together they uncover additional victims and signs of a significant cover-up. Stopping the murders, protecting her employment, and ensuring her own survival will require Triana's technical skills, O'Neill's connections, and determination. This is the first book in a completed series.
