Light of the Realm - Robert Ryan - Bog

The final battle approaches, and the threads of prophecy tighten...
Gil has not discovered how to defeat the sorceress who threatens the realm. And time has run out. Ginsar commands not only blood magic, nor just the terrifying Horsemen, but also a vast army - and it is massed mere days away.
But Gil's people will not cower behind walls of stone. No enemy has ever breached the city defenses, but aided by sorcery this one will. So, Gil leads the army on a sudden march to take the fight to Ginsar before she is ready. It is a desperate gamble, and one that could turn to ruin and despair.
Strategies come to fruition, ploys unfold and traps are set. Prophecies for the future vie with secrets hidden in the past. It is a time of turmoil, a time of chaos, and a time where gambles could triumph - or destroy worlds. Gil is at its heart, ready to be king, but perhaps fated to see all that he loves burn to ash and smoke...
This is the final book of the Son of Sorcery trilogy.
