Faery Sovereign

When ancient evil threatens the heart of all magic, Kevin joins the battle...

Magic's secret heart hides in the depths of the Faery realm, protected for millennia by mystery and shadow. Until the most powerful enemy the realm has ever faced invades. And Kevin becomes the only one strong enough to lead the fight.
He must find a way to save the faery princess Silver and square off against assassins and friends-turned-rivals to reach magic's heart before the invader strikes. But winning the race isn't the only thing that matters.

The more magic Kevin uses, the more he risks destroying everything that makes him human. And the enemy? She's a Horseman of the Apocalypse...
Failure is not an option. Kevin will win-or die trying.
