Live - stone Hunters. Return of the Gryphons, #3

Enemies within, monsters without. And the mages controlling the gryphons' are waiting to strike. To defeat the Khol-Reyne, Mark must convince the ancient Delven - carvers of the living stone beasts - to join the fight. But their mountain realm is treacherous, and old hatreds still fester among Mark's allies. Worse, a rogue mage with a vendetta is playing his own deadly game. He may be their best hope - or their final undoing.
As the gryphons grow stronger and strange new powers stir, Mark must make an impossible choice: risk everything on a desperate alliance, or let the Duchy crash into oblivion along with its allies. Live-Stone Hunters is a tale of ancient secrets, fractured trust, and beasts that remember their makers. The storm is coming. And everyone is hunting something.
