The Raevnir, once dragons, now rule as kings. When King Raelith dies, his eldest son, Kassian, is named heir-strong, just, and everything a ruler should be. But his younger brother, Eryx, refuses to be forgotten. Born in Kassian's shadow, Eryx is cruel, reckless, and desperate to claim power for himself. When an ancient god whispers promises of a throne that must be taken, not given, Eryx listens.
Beneath them, Veranis, their bastard half-brother, suffers in silence. Born to be a whipping boy, his silver wings are broken more often than they fly. He has spent his life bleeding for Eryx, but as war looms, he must make a choice-remain a pawn, or carve his own path in the ashes. As the battle for the throne begins, brother will rise against brother, betrayal will stain the sky, and the Black Sun will never set.
