Sinner — Sara Douglass

The land of Tencendor has been united for more than forty years, thanks to Axis, who is the legendary Starman. He defeated Gorgrael and brought peace to the three races--and upon fulfilling his destiny, Axis and his consort Azhure retired to the ethereal sphere in the heavens, and ceded his authority to their son Caelum.

But the path of the son is not necessarily that of the father. Caelum is untried and has known nothing but peace during his lifetime. And while the three races seem to be at peace, there are undercurrents of jealousy and bitter memories buried just beneath the surface.

So when strange powers begin to manifest in their world, and threaten the destruction of all he holds dear, Caelum will have to find the strength to fight this threat--and to fight his mortal brother Drago, who is not as powerless as he appears to be. Something killed their sister, and Caelum knows Drago is the culprit--but the Supreme Ruler of the land must have proof, and Caelum has none.

Caelum desperately tries to juggle saving the world with proving his brother killed their sister, but time grows short and the demons are drawing near...
