Lacey Chu has always dreamed of working as an engineer for MONCHA, the biggest tech firm in the world and the company behind the "baku," a customizable "pet" with all the capabilities of a smartphone. But when Lacey is rejected by the elite academy that promises that future, she's crushed. One night, Lacey comes across the broken form of a highly advanced baku. After Lacey repairs it, the cat-shaped baku she calls Jinx opens its eyes and somehow gets her into her dream school. Jinx is definitely different than any other baku she's ever seen. He seems…real. Lacey settles into life at school, competing with the best students in a battle of the bakus that tests her abilities. But then she learns that Jinx is part of a dangerous secret. As she's drawn into a web of lies and drifts further away from her family and her old friends, can Lacey hold onto Jinx and her dreams for the future?
