From the back of the book: "Two centuries after a devastating interplanetary religious war, the galaxy is under the iron grip of the "Great Quartet" - four dieties who've outlawed all rival beliefs and unleashed the Divine Legions to crush dissent. But faith is resilient, and in the shadows of this cosmic tyranny, ancient alien religions survive through relics smuggled across star systems. Enter Xia, a fearless human relic hunter, and Little Mercur, her masked alien partner with secrets of his own. Together, they navigate the black-market underworld of outlawed artifacts, joined by Vitellius - a disgraced centurion turned rogue. Their latest mission? Retrieve a relic from a hostile planet where danger lurks in every crater and betrayal is just a warp jump away."
