Luna is set in the year 2110 on the moon, which over the previous 60 years has been colonized and industrialized. It is controlled by five powerful, highly competitive dynastic corporate families (known as the Five Dragons) who run their various business enterprises with an iron fist in a near-feudal society. The moon, under the control of the Five Dragons, is a lucrative source of valuable resources such as Helium-3, carbon, water ice and rare metals, which are exported back to Earth for huge profits.
Forty years ago, Adriana wrested control of the moon's lucrative Helium-3 industry from the powerful Mackenzie Metal corporation. Now, in the twilight of her life, Adriana finds her corporation, Corta Helio, surrounded by the many enemies she made during her meteoric rise. If the Corta family is to survive, Adriana's five children must defend their mother's empire from her many enemies… and each other.
