Gorp: Dungeon Overlord [EPUB ebook] 

Gorp the goblin through a series of unlikely events finds himself in charge of Ye Olde Dungeon as the new Dungeon Overlord. Gorp has made great improvements and increased the efficiency of dungeon operations, but a new threat from the west brings an unwelcome change to the realm in the form of an orc invasion. Not only is the dungeon in trouble of being overrun by orcs, but King Gilden blames Ye Olde Dungeon as the cause of the invasion. That is until the Fae Kingdom offers an alliance after Gorp helps rescue the fairy princess who has been lost in the City of Tents to the south after a bad break up.
