Hawkmoon: The Mad God's Amulet #2

Set in a post-apocalyptic age of primitive industrialist technology and futuristic dark magic, Europe has been conquered by the tyrannical Granbretan empire led by King-Emperor Huon. Dorian Hawkmoon faces a race against a ticking clock to gain control over the black jewel embedded in his head and his only hope comes in the form of a hermit mage in a distant land. It is up to the Duke and a few strange allies to thwart the cult’s twisted beliefs and find the mage to allow Dorian Hawkmoon to lead the fight against the Granbretan Empire.
