The Stars Are Calling (Aphelion Worlds)

Out in the aphelion worlds, fifteen lightyears past nowhere, two law officers stand for justice in a system where avarice and graft are the law of the land. They’re sent on a mission to investigate the wreckage of a postal carrier. What they find there will throw them into the center of a plot to overthrow the Grand Premiere, leader of the Colonial Federation. But with trust long gone and friends and foes flip flopping between sides saving the Grand Premiere won't be easy. In the end, will they serve justice or her sighted sister avarice?
