The Wolf's Call: Book One of Raven's Blade

Anthony Ryan's Raven's Shadow trilogy took the fantasy world by storm. Now he returns to the world of this acclaimed series with The Wolf's Call, an action-packed new adventure featuring fan-favourite Vaelin Al-Sorna.
A STORM IS COMING
Vaelin Al Sorna is a living legend. It was his leadership that overthrew empires, his blade that won hard-fought battles, and his sacrifice that saved the Unified Realm from destruction. Yet Vaelin has turned his back on prestige and glory to live a quiet life in the Realm's northern reaches.
Now whispers have come across the sea of an army called the Steel Horde, let by a man who believes himself a god. Vaelin has no desire to fight another war, but when he learns that Sherin, the woman he lost long ago, has fallen into the Horde's grasp, he resolves to confront this powerful new threat.
To do so, Vaelin travels to the realms of the Merchant Kings, a land ruled by honour and intrigue. And as the drums of war echo across kingdoms riven by conflict, Vaelin learns that there are some battles even he cannot hope to win.
