Sullivan, Michael J., 1961- Legends of the First Empire #1

"Michael J. Sullivan's trailblazing career began with the breakout success of his Riyria series: full-bodied, spellbinding fantasy adventures whose imaginative scope and sympathetic characters won a devoted readership and comparisons to fantasy masters Brandon Sanderson, Scott Lynch, and J.R.R. Tolkien himself. Now, Sullivan's stunning hardcover debut, Age of Myth, inaugurates an original five-book series--and one of fantasy's finest next-generation storytellers continues to break new ground. Since time immemorial, humans have worshipped the gods they call Fhrey, truly a race apart: invincible in battle, masters of magic, and seemingly immortal. But when a god falls to a human blade, the balance of power between humans and the those they thought were gods changes forever. Now only a few stand between humankind and annihilation: Raithe, reluctant to embrace his destiny as the God Killer. Suri, a young seer burdened by signs of impending doom. And Persephone, who must overcome personal tragedy to lead her people. The Age of Myth is over. The time of rebellion has begun"--

"A new series set in the world of the Riyria Chronicles. In the land of the Rhune, trees can tell the future and the gods are beyond reproach. But when Raithe's father is slain, he does the unthinkable--he kills a god. From this act, rises the legend of the God Killer, the seeds of a rebellion, and the question of whether the gods are really immortal after all"--
