Shadowstorm

Surrounded by evil on all sides, Erevis Cale and his comrades continue their fight against the Shar in this second adventure in the Twilight War series
 
The Archwizards of Shade Enclave have emerged from the desert with a message of peace and an act of war. Split by petty disputes and causeless feuds, the merchant realm of Sembia is wide open for invasion.
 
With many Sembians more than happy to sell out to the Shadovar, can only one man do anything to stop it? Erevis Cale is more than willing to try, though he must make a deal with a devil along the way—a deal that will tear a friend’s soul in two but is key to preventing the realms from being torn asunder by the Shadowstorm.
