maya chen is a cryptography researcher trapped in a locked-down facility. the only way out is through the terminal. you write real Go code to open doors, decode schedules, hijack comm relays, and fight your way past security systems. every chapter teaches new Go concepts. every line you write compiles on the real Go Playground. by the end, you know Go.
