ABOUT THE BOOK:
In this dark fantasy adventure, journey to the Skovos Isles and uncover their mysteries: a lost expedition of mages, a dangerous monster, and a boiling political conflict—the official prequel to Diablo IV: Lord of Hatred.
An ancient brotherhood of mages and wizards sworn to defend humanity against evil is on the brink of destruction.
Their last good chance at survival is to journey to the far-off Skovos Isles and uncover the fate of a long-lost expedition sent to unlock a vault hidden deep within its lands.
But what awaits them is more than they bargained for. The Amazon warriors who call Skovos home face two dangerous threats: the rumblings of a disquieted public, and an undead creature attacking them from all sides.
The leader of the mages, Lorath, and Captain Adreona of the Amazons must band together in an unlikely alliance to unlock these mysteries . . . or else the mortal realm may be in terrible danger.
