Ambassador 1

24 October 2114: the day that shocked the world.
Young diplomat Cory Wilson narrowly escapes death in the assassination of President Sirkonen. No one claims responsibility but there is no doubt that the attack is extraterrestrial.
Cory was meant to start work as a representative to Gamra, the alien organisation that governs the FTL transport network, but now his new job may well be scrapped in anger.
Worse, as Earth uses military force to stop any extraterrestrials coming or leaving, as 200,000 extraterrestrial humans are trapped on Earth, as the largest army in the galaxy prepares to free them by force, only Cory has the experience, language skills and contacts to solve the crime.
But he's broke, out of a job and a long way from Earth.
