Light of the Radiant — Matthew Ward

Arrogance is more dangerous than a sword.At long last, there is peace between the Tressian Republic and the Hadari Empire. But it is not welcomed by all. Leaders from both realms watch their counterparts with suspicion, expecting the swift return of the centuries-long war. But mortals are not the only ones readying for strife. Deep below the Contested Lands, cultists labour to rouse ancient evils from slumber. In the skies above, the legendary serathi, handmaidens of the Radiant, have at last returned from their self-imposed exile. But why now?Once again, it falls to Edric Saran and his allies to unravel the mystery before it's too late. The Light of the Radiant has the power to change everything, but at what cost?
