Frostborn: Excalibur (Frostborn #13)

Ridmark Arban is the Gray Knight, leading the defense of Andomhaim from the brutal Frostborn.

Yet the realm of Andomhaim is riven with civil war. The false king Tarrabus has usurped the crown in the name of the shadow of Incariel, and the loyal lords must fight the ruthless rebels.

Unless Ridmark can defeat Tarrabus and reunify Andomhaim, the Frostborn will prevail.

But Tarrabus Carhaine, deadly and wicked, will not be defeated without terrible cost...
