Destiny — Sharon Green

The Six are stronger than the Five ...
But the darkness is most powerful of all

Naran's remarkable Sight magic completed the Blending and brought solidity to their rule. But even their combined elemental powers--Earth, Fire, Air Water, Spirit and Sight--will not turn back the dark clouds of destruction massing at Gandistra's border. For war is inevitable, as a horrific army led by a faceless malevolent entity sweeps relentlessly across the neighboring lands, enslaving, devouring, and destroying everything in its path. And fallen nobles closer to home implement dire schemes to unseat the reigning Six, intent on regaining the throne through the blackest of acts: mass murder. Only by developing new, untested abilities--and unearthing startling secrets buried centuries ago--can Lorand, Rion, Tamrissa, Valiant, Jovvi and Naran hope to prevail.

The hour of reckoning is finally at hand. All else was a mere training for a grim and terrible destiny that they cannot avoid.
