Dragon Unity

One herald has been stopped. Rob must progress to stop them all.
With the Eternal now captive, Rob wants answers. A greater danger is coming, and it's one he knows nothing about.
But the Eternal refuses to tell him anything.
Rob knows other heralds will come. As the borders of his realm are attacked, his mastery of unity is key to stopping them-only this time it's not strong enough.
He needs more power. He needs to progress.
But how can he progress when he doesn't know what comes next?
And can he do it before this overwhelming power reaches his land?
Dragon Unity is book 12 in an exciting progression fantasy series!
