Twenty-two-year-old Tia Moreno never expected her first job as a robotics technician on Unity, a city-sized space station, to turn into a deadly game of cat and mouse. But when strange vibrations lead to the discovery of a serial killer lurking among the station's residents, Tia must use her knowledge of robots to track down the elusive murderer. As the killer's body count rises, Tia realizes she may be the only one who can stop him before he destroys everything she's come to love. With the help of the station AI and her new friend Minji, Tia races against time to catch the killer before he strikes again.
Fans of sci-fi thrillers will be on the edge of their seats as Tia fights to save Unity from a seemingly unstoppable villain. Readers who enjoyed Andy Weir's Project Hail Mary will be hooked by the high-stakes action and futuristic setting of Critical Balance.
