Eclipse of the Sun — Matthew Allen Dickerson

The spirit of a murdered princess is in need of noble warriors to free the cursed soul of her father. An ancient sorcerer seeks aid in stopping his son who is determined to exterminate all sentient life. What they find is Nathaniel and Sebastian, a pair of con artists and thieves, that wants nothing to do with acts of heroism. Did destiny make a mistake in choosing these two? Probably, but it's too late now.
