The Radiant King

The first installment of USA Today bestseller David Dalglish's latest epic fantasy trilogy about immortal demigods, civil wars, and ancient evil will be irresistible to classic fantasy fans and will appeal to readers of James Islington and Anthony Ryan.​
Six immortal siblings. Five sworn to peace. One demands a throne.
Radiance, the mysterious power of life and creation, is theirs to command. Death cannot claim them. For hundreds of years, the ever-living ruled with ease. Yet when the world is nearly broken beneath their reign, the humbled six swear a vow: They will sit upon no thrones, wear no crowns, and no longer teach humanity the gifts of radiance.
But after centuries of peace, Eder rejects their vow, anoints himself Voice of Father, and spreads a new, cruel faith across the land.
Faron cannot allow such indiscretion. Returning from a self-imposed exile, he swears to crush Eder’s kingdom, and he will not do so alone—Sariel, their cold and calculating brother, knows all too well that an ever-living’s dominion is bound for brutality and destruction. But to overthrow a nation, they will need more than each other. They will need an army and a ruler who can take the throne their own vow forbids. And so, they pledge themselves to the fanatical Bastard Princess, a woman with incredible powers she insists were given to her by the goddess Leliel.
But Eder’s conquest is not what it seems, and it will take more than a holy war to stop an immortal who has heard the desperate plea of a god.
