The Fall of Shaylar — River Fairchild

Prequel to the Jewels of Chandra series
Magic is real. So is betrayal.
One thousand years before the series Jewels of Chandra, the Kingdom of Shaylar plunged into chaos.
Before the fall, before the wizards interfered, before the Kingdom crumbled to dust, the highborn monarch of Shaylar ruled in peace.
Rivalry, jealousy, a desperate attempt to grab the magic of Shaylar -- all converge to bring about the end of the precarious balance between the Five Kingdoms.
As King Narmek and Queen Meelate celebrate the birth of their twin boys, the seeds of malice are sown. But the grab for power began with the wizards long before that.
