The Struggle - Demon Land, #1

The angels that ruled the world are long dead, and tomorrow belongs to the demons. Splinter, a young, wingless demon aristocrat, has a choice: accept his place in the empire, inheriting a castle and a magic sword, or place his trust in his human girlfriend and their sorcery tutor, joining a terrorist plot that may spill more blood and bring more misery than the brutal wars of centuries past. "The Struggle" is the first book in the saga of Demon Land, the continent where the desperate Empire of Apollyon strives to invade, infest, and infect, the world of Erde.
