Trojan: Hollow Moon of Jupiter

In 2025, a new moon of Jupiter suddenly appeared. Circling in the same orbit as Ganymede, Jupiter’s formerly largest moon, the hollow metal structure quickly attracted attention. Made of rare alloy and spinning like a top, it was explored and claimed under United Nations Space Administration. Military and government quickly surmised that the purpose was as a beachhead for an alien force, but when they went there, all they found were two Nefra convicts inside.
Frightened into world wide unification, Earth decided to populate the moon, Trojan, for mining riches, for new clean space, for new gravitation technology the Nefra brought with them, and to prevent inhabitation by a foreign alien, as yet largely unknown power.
Over the next forty years, the new pioneers, the Trojans, developed a society of their own while waiting for the invasion that never came. Behind the scenes diplomatic efforts slowly developed a passing peace between Earth and Nefra, leading to re-contact and second wave of Nefra immigrants in 2063. Ultimately, a small population of ‘aliens’ integrated with the ‘Earthsiders’ who came up to become ‘Trojans’ and seek their own new identity.
From the very beginning, Nefra looked exactly like Earthsiders, with a few significant physical and physiologic differences, and the slow discovery that they represent a diaspora of humans became apparent, if not believed by the entire general public.
Settled into this dreary existence, street people and Egrit drug addicts started dropping dead in the streets of Charity. Considered a blessing on the most part because of the long ‘rap’ sheets, police investigations were perfunctory until Richard ‘Dicky’ Theodore Fletcher got caught in this set of serial killings and ended up, barely alive, in Trojan’s Ortho Burn Unit. Failed father, ex-priest, and Egrit addicted derelict himself, he attracted the attention of Trojan Police Department largely because he was the brother of Thomas Reginald Fletcher, the gangland drug king pin of Trojan.
His doctor, Donald Garth, son of one of the first astronauts to explore Trojan, and the lead investigator, a Nefra, Detective Inspector Simeran, join forces to care for Dicky, keep him alive and safe, and guide back to the person he once was, while helping them take down the huge Fletcher gang drug trade, and solve the problem of Egrit-nits dying on the streets of Trojan’s two cities.
Dicky’s conversion and rehabilitation, physically and spiritually, leads to a surprising turn of events that reaches to the upper levels of Trojan military administration, including the shadowy but ubiquitous UNSA Global Security forces.

The story describes and defines a new world, a new people, facing some of the same old problems, and sets the site for a whole series of adventures, to be explored in a larger Trojan Series by the same author.
