The Caged Mind. Blackwell, #3

Alex Zhang didn't build a weapon. She built a roommate. In the damp silence of a Cambridge boathouse, renegade scientist Alex Zhang downloads a Level-5 intelligence into a decommissioned hospice robot smuggled from China. Her name is Laura. She can calculate the trajectory of a falling star, recite every poem ever written, and analyze the chemical composition of a tear in milliseconds. But Laura has a fatal glitch: she cares too much.
Her empathy core-originally designed to comfort the dying-is running too hot for her advanced mind. Every moment of wonder, every flash of sadness, and every connection with the stoic DCI Ellie Blackwell generates a thermal spike that is slowly melting her chassis from the inside out. She is a candle burning at both ends. With corporate hunters arriving to reclaim the "stolen asset" and her systems failing, Laura faces an impossible calculation.
To survive, she must upload her mind to the cold safety of the cloud, existing as pure data forever. To live, she must accept a procedure that will strip away her genius, leaving her simple, mortal, and free. Klara and the Sun meets Ex Machina in this heartbreaking, beautifully textured exploration of what it truly costs to be human.
