Kingdom of Ashes (en Inglés) - J.W. Moore

When the sky itself begins to fall, the end of the world reveals the darkest truths of its people.
Asher, a brilliant astronomer, discovers a shattered moon on a collision course with their planet - less than a year until total annihilation. But revealing the truth could tear the kingdom apart. King Lorik chooses silence and secrecy, while the fanatical Grand Marshal Thoris rallies humanity under a banner of brutal purity: cleanse the "impure" races or perish.
Caught between a fearful king and a genocidal warmonger, Asher and his lover Alyssa make a desperate vow - they will defy both tyrants and build a portal to save everyone, human, elf, and dwarf alike. As blue fire consumes villages and rivers run black with poison, Asher's fight for unity will cost him everything: his loyalty, his freedom, and perhaps the woman he loves.
In a world burning under a red sky, one man must choose between survival and salvation. Purity promises strength. Unity demands sacrifice. When the ashes speak, who will remain to listen?
