Whistling Past the Graveyard: Prequel to the Saga of Shadows - Kevin J. Anderson

In the prequel to the Saga of Shadows trilogy and Hugo Award nominee The Dark Between the Stars, humanity recovers from war as new threats loom.
Nine years have passed since the end of the titanic Elemental War, and the human race is still picking up the pieces. The Terran Hanseatic League has become the Confederation, and King Peter and Queen Estarra work to heal wounds among the factions of humanity, as well as with the alien Ildiran Empire.
Trade Minister Rlinda Kett seeks to reestablish contact with lost human colonies that have vanished in the chaos, and she travels to a planet called Happiness, site of an isolated neo-Amish colony where the treacherous Prince Daniel was exiled. As a civil war brews among the Roamer clans over the old ways versus new business methods, some brave clans venture back to skymining again, harvesting the restless clouds of huge gas giant planets-where the threat of the devastating hydrogue aliens always looms . . .
"A setting so rich and detailed that the reader will suspend disbelief and actually be there." -R. A. Salvatore
